KINSHASA, CONGO — Public health officials in Africa urged caution Thursday as Congo’s health minister said the government was on alert over a mystery flu-like disease that in recent weeks killed dozens of people.

Jean Kaseya, the head of Africa Centers for Disease Control and Prevention, told reporters that more details about the disease should be known in the next 48 hours as experts receive results from laboratory samples of infected people.

“First diagnostics are leading us to think it is a respiratory disease,” Kaseya said. “But we need to wait for the laboratory results.” He added that there are many things that are still unknown about the disease — including whether it is infectious and how it is transmitted.

Authorities in Congo have so far confirmed 71 deaths, including 27 people who died in hospitals and 44 in the community in the southern Kwango province, Health Minister Roger Kamba said.

“The Congolese government is on general alert regarding this disease,” Kamba said, without providing more details.

Of the victims at the hospitals, 10 died due to lack of blood transfusion and 17 because of respiratory problems, he said.

The deaths were recorded between November 10 and 25 in the Panzi health zone of Kwango province. There were around 380 cases, almost half of which were children under the age of 5, according to the minister.

The Africa CDC recorded slightly different numbers, with 376 cases and 79 deaths. The discrepancy was caused by problems with surveillance and case definition, Kaseya said.

Authorities have said that symptoms include fever, headache, cough and anemia. Epidemiological experts are in the region to take samples and investigate the disease, the minister said.

The Panzi health zone, located around 700 kilometers from the capital, Kinshasa, is a remote area of the Kwango province, making it hard to access.

The epidemiological experts took two days to arrive there, the minister said. Because of the lack of testing capacity, samples had to be taken to Kikwit, more than 500 kilometers away, said Dieudonne Mwamba, the head of the National Institute for Public Health.

“The health system is quite weak in our rural areas, but for certain types of care, the ministry has all the provisions, and we are waiting for the first results of the sample analysis to properly calibrate things,” Kaseya said.

Mwamba said that Panzi was already a “fragile” zone, with 40% of its residents experiencing malnutrition. It was also hit by an epidemic of typhoid fever two years ago, and there is currently a resurgence of seasonal flu across the country.

“We need to take into account all this as context,” Mwamba said.

A Panzi resident, Claude Niongo, said his wife and 7-year-old daughter died from the disease.

“We do not know the cause, but I only noticed high fevers, vomiting … and then death,” Niongo told The Associated Press over the phone. “Now, the authorities are talking to us about an epidemic, but in the meantime, there is a problem of care [and] people are dying.”

FREETOWN, SIERRA LEONE — Authorities in Sierra Leone on Thursday started a nationwide rollout of the single-dose Ebola vaccine, the first such campaign in West Africa, where a deadly outbreak 10 years ago resulted in the death of thousands.

The 2014 Ebola outbreak — the deadliest in history — was primarily in West Africa but affected Sierra Leone the most, with nearly 4,000 deaths out of the more than 11,000 recorded globally. The country also lost 7% of its health care workforce to the outbreak.

The nationwide vaccine campaign, implemented by the government in partnership with the global vaccine alliance Gavi, the World Health Organization and the United Nations children’s agency, will target 20,000 front-line workers across the country, officials said.

“This is an investment in the safety of our people and a healthier Sierra Leone,” Health Minister Austin Demby said.

There had been no approved vaccine at the time of the 2014 outbreak, which recorded up to 28,000 cases, starting in Guinea before spreading across land borders to Sierra Leone and Liberia, the other two countries affected the most.

Three years have passed since the last case was recorded in Guinea, although officials have spoken of remaining threats in endemic regions.

Among those killed by the disease during the 2014 outbreak were nine relatives of Hassan Kamara, a resident of Freetown. Of the 11 people he was living with at the time, only he and his baby daughter survived.

“They died in front of me,” he said. “I feel bad sometimes speaking about this because of what I went through.”

Thursday’s campaign, which launched in the capital, Freetown, was welcomed by health workers.

Collins Thomas, a community health worker in Freetown, remembers losing many colleagues in 2014 as they managed patients during the outbreak in Freetown.

“It was scary, because we knew nothing about the disease and learned along the line. With this vaccine, we know we are protected,” Thomas said.

Gavi Chief Executive Sania Nishtar said the organization is “incredibly proud” of how its support for timely and equitable access to vaccines has helped save lives and protect communities.

“To have the first nationwide preventive vaccination campaign take place in the country most deeply impacted by the 2014 outbreak makes this historic milestone even more meaningful,” he said.

WASHINGTON — The Supreme Court is hearing arguments Wednesday in just its second major transgender rights case, which is a challenge to a Tennessee law that bans gender-affirming health care for minors.

The justices’ decision, not expected for several months, could affect similar laws enacted by 25 other states and a range of efforts to regulate the lives of transgender people, including which sports competitions they can join and which bathrooms they can use.

The case is coming before a conservative-dominated court after a presidential election in which Donald Trump and his allies promised to roll back protections for transgender people.

There were dueling rallies outside the court in the hours before the arguments. Speeches and music filled the air on the sidewalk below the court’s marble steps. Advocates of the ban bore signs like “Champion God’s Design” and “Kids Health Matters,” while the other side proclaimed “Fight like a Mother for Trans Rights” and “Freedom to be Ourselves.”

Four years ago, the court ruled in favor of Aimee Stephens, who was fired by a Michigan funeral home after she informed its owner that she was a transgender woman. The court held that transgender people, as well as gay and lesbian people, are protected by a landmark federal civil rights law that prohibits sex discrimination in the workplace.

The Biden administration and the families and health care providers who challenged the Tennessee law are urging the justices to apply the same sort of analysis that the majority, made up of liberal and conservative justices, embraced in the case four years ago when it found that “sex plays an unmistakable role” in employers’ decisions to punish transgender people for traits and behavior they otherwise tolerate.

The issue in the Tennessee case is whether the law violates the equal protection clause of the 14th Amendment, which requires the government to treat similarly situated people the same.

Tennessee’s law bans puberty blockers and hormone treatments for transgender minors, but not “across the board,” lawyers for the families wrote in their Supreme Court brief. The lead lawyer, Chase Strangio of the American Civil Liberties Union, is the first openly transgender person to argue in front of the justices.

The administration argues there is no way to determine whether “treatments must be withheld from any particular minor” without considering the minor’s sex.

“That is sex discrimination,” Solicitor General Elizabeth Prelogar wrote in her main court filing.

The state acknowledges that the same treatments that are banned for transgender minors can be prescribed for other reasons. But it rejects the claim that it is discriminating on the basis of sex. Instead, it says lawmakers acted to protect minors from the risks of “life-altering gender-transition procedures.”

The law “draws a line between minors seeking drugs for gender transition and minors seeking drugs for other medical purposes. And boys and girls fall on both sides of that line,” Tennessee Attorney General Jonathan Skrmetti wrote in the state’s Supreme Court brief.

While the challengers invoke the 2020 ruling in Bostock v. Clayton County for support, Tennessee relies on the court’s precedent-shattering Dobbs decision in 2022 that ended nationwide protections for abortion and returned the issue to the states.

The two sides battled in their legal filings over the appropriate level of scrutiny the court should apply. It’s more than an academic exercise.

The lowest level is known as rational basis review and almost every law looked at that way is ultimately upheld. Indeed, the federal appeals court in Cincinnati that allowed the Tennessee law to be enforced held that lawmakers acted rationally to regulate medical procedures, well within their authority.

The appeals court reversed a trial court that employed a higher level of review, heightened scrutiny, that applies in cases of sex discrimination. Under this more searching examination, the state must identify an important objective and show that the law helps accomplish it.

If the justices opt for heightened scrutiny, they could return the case to the appeals court to apply it.

Gender-affirming care for youth is supported by every major medical organization, including the American Medical Association, the American Academy of Pediatrics and the American Psychiatric Association.

But Tennessee is pointing to health authorities in Sweden, Finland, Norway and the United Kingdom that found the medical treatments “pose significant risks with unproven benefits.”

None of those countries has adopted a ban like the one in Tennessee, and individuals can still obtain treatment, Prelogar wrote in response.

The Williams family of Nashville, Tennessee, are among those challenging the state law. Brian Williams said that because of puberty blockers and hormone treatments, his transgender daughter, L.W., is a “16-year-old planning for her future, making her own music and looking at colleges.”

But because of Tennessee’s ban, she has to travel to another state to receive the health care that “we and her doctors know is right for her.”

WASHINGTON — When the Supreme Court this week wades into the contentious issue of transgender rights, the justices will hear from an attorney with knowledge that runs deep.

Chase Strangio will be the first openly transgender attorney to argue before the nation’s highest court, representing families who say Tennessee’s ban on health care for transgender minors leaves their children terrified about the future.

Arguments in the case come amid heightened pushback to transgender rights, including a presidential campaign where Republican Donald Trumpput his fierce opposition front and center.

Strangio will bring months of intense legal preparation to the case as well as hard-won lessons from his own experience.

“I am able to do my job because I have had this health care that transformed and, frankly, saved my life,” he said. “I am a testament to the fact that we live among everyone.”

Strangio grew up outside of Boston and came out as trans when he was in law school. Now 42, he’s an American Civil Liberties Union attorney whose legal career has included representing former Army intelligence analyst Chelsea Manning, challenging a ban on transgender people serving in the military and helping win an LGBTQ+ worker-discrimination case at the Supreme Court. He’s also the father of a 12-year-old, the son of a father who supports Trump, and has a close relationship with his Army-veteran brother.

He’s also an advocate, speaking out as a series of U.S. states banned gender-affirming health care for transgender minors. The laws are part of a wave of restrictions on school sports participation and bathroom usage around the country. After the first openly transgender person was elected to Congress, Republican House Speaker Mike Johnson declared support for restricting bathroom use to sex assigned at birth.

Tennessee, meanwhile, will argue before the Supreme Court that treatments like puberty blockers and hormones carry risks for young people and that its law protects them from making treatment decisions prematurely.

“Tennessee, like many other states, acted to ensure that minors do not receive these treatments until they can fully understand the lifelong consequences or until the science is developed to the point that Tennessee might take a different view of their efficacy,” state attorneys wrote in court filings.

Arguing for Tennessee is state Solicitor General Matt Rice. He served in 2019 as a clerk for Justice Clarence Thomas, who dissented from the transgender worker-discrimination case Strangio worked on that term. The state attorney general’s office did not make Rice available for an interview ahead of arguments, but his background also includes a couple of years as a minor league baseball player for the Tampa Bay Rays before he earned his law degree from the University of California, Berkeley.

The Biden administration is supporting the challenge to Tennessee’s law, but the federal government’s position is expected to change after Trump takes office in January. 

Strangio said he’ll nevertheless keep advocating for transgender youth to access health care that wasn’t available when he was young.

“Many of us think about our childhood and young adulthood as lost years, when we were just simply disembodied from our core,” he said. Major medical groups, including the American Medical Association and the American Academy of Pediatrics, oppose the bans and have endorsed such care, saying it’s safe when administered properly. 

Strangio also pointed out that many medical interventions for young people, like gastric bypass surgeries for weight loss, carry some risk and it makes sense to inform families and let them decide.

“There is harm that is compounded when we are forcing young people to be denied care that their doctors and their parents and they themselves all agree they need,” he said.

The Supreme Court is expected to decide the case by the summer.

Washington — President Joe Biden on Sunday had the AIDS Memorial Quilt spread on the White House South Lawn for the first time in observance of World AIDS Day.

Gathered with the president and his wife, Jill, were survivors, family members and advocates to memorialize the lives lost to the epidemic. The president emphasized the federal government’s support for the 1.2 million people in the United States living with the human immunodeficiency virus (HIV), which can lead to AIDS.

“This movement is fully woven into the fabric and history of America,” Biden said. “For all the lives lost, for all those that are still alive, look at what you’ve already done to change the hearts and minds, to save lives across the country and around the world. That’s the power of this movement.”

There were 124 sections of the quilt on the lawn to commemorate people who died due to AIDS-related illnesses. Conceived in 1985, the quilt made its first public appearance in 1987. There was also a red ribbon, a symbol of support and awareness for those with HIV and AIDS, draped across the South Portico of the White House.

There are 40 million people around the world with HIV, according to the White House.

Introducing Biden was Jeanne White-Ginder, whose son, Ryan White, contracted AIDS through a tainted blood transfusion at the age of 13 and died in 1990 at the age of 18. She said her son’s experience taught America that “we needed to fight AIDS and not the people who have it.”

The Ryan White CARE Act became law in 1990, and White-Grinder recalled being at the U.S. Capitol to speak for the measure and met Biden when he was a senator from Delaware.

The president also saluted Dr. Anthony Fauci, the top U.S. infectious disease expert until leaving the government in 2022, Fauci was in attendance at the event as he worked to treat AIDS, though he’s known by much of the country for his efforts to address the coronavirus pandemic that made him a target of criticism by many Republican lawmakers.

The Biden administration has sought to make investments to stop the epidemic, and the stigmas attached to people with HIV. Among other steps, it has worked to expand access to PrEP, or the pre-exposure prophylaxis, which at-risk populations use to prevent HIV infections.

The Hague — The top United Nations court will take up the largest case in its history Monday, when it opens two weeks of hearings into what countries worldwide are legally required to do to combat climate change and help vulnerable nations fight its devastating impact.

After years of lobbying by island nations who fear they could simply disappear under rising sea waters, the U.N. General Assembly asked the International Court of Justice last year for an opinion on “the obligations of States in respect of climate change.”

“We want the court to confirm that the conduct that has wrecked the climate is unlawful,” Margaretha Wewerinke-Singh, who is leading the legal team for the Pacific island nation of Vanuatu, told The Associated Press.

In the decade up to 2023, sea levels have risen by a global average of around 4.3 centimeters (1.7 inches), with parts of the Pacific rising higher still. The world has also warmed 1.3 degrees Celsius (2.3 Fahrenheit) since pre-industrial times because of the burning of fossil fuels.

Vanuatu is one of a group of small states pushing for international legal intervention in the climate crisis.

“We live on the front lines of climate change impact. We are witnesses to the destruction of our lands, our livelihoods, our culture and our human rights,” Vanuatu’s climate change envoy Ralph Regenvanu told reporters ahead of the hearing.

Any decision by the court would be non-binding advice and unable to directly force wealthy nations into action to help struggling countries. Yet it would be more than just a powerful symbol since it could serve as the basis for other legal actions, including domestic lawsuits.

On Sunday, ahead of the hearing, advocacy groups will bring together environmental organizations from around the world. Pacific Islands Students Fighting Climate Change — who first developed the idea of requesting an advisory opinion — together with World Youth for Climate Justice plan an afternoon of speeches, music and discussions.

From Monday, the Hague-based court will hear from 99 countries and more than a dozen intergovernmental organizations over two weeks. It’s the largest lineup in the institution’s nearly 80-year history.

Last month at the United Nations’ annual climate meeting, countries cobbled together an agreement on how rich countries can support poor countries in the face of climate disasters. Wealthy countries have agreed to pool together at least $300 billion a year by 2035 but the total is short of the $1.3 trillion that experts, and threatened nations, said is needed.

“For our generation and for the Pacific Islands, the climate crisis is an existential threat. It is a matter of survival, and the world’s biggest economies are not taking this crisis seriously. We need the ICJ to protect the rights of people at the front lines,” Vishal Prasad, of Pacific Islands Students Fighting Climate Change, told reporters in a briefing.

Fifteen judges from around the world will seek to answer two questions: What are countries obliged to do under international law to protect the climate and environment from human-caused greenhouse gas emissions? And what are the legal consequences for governments where their acts, or lack of action, have significantly harmed the climate and environment?

The second question refers to “small island developing States” likely to be hardest hit by climate change and to “members of “the present and future generations affected by the adverse effects of climate change.”

The judges were even briefed on the science behind rising global temperatures by the U.N.’s climate change body, the Intergovernmental Panel on Climate Change, ahead of the hearings.

The case at the ICJ follows a number of rulings around the world ordering governments to do more to reduce greenhouse gas emissions.

In May, a U.N. tribunal on maritime law said that carbon emissions qualify as marine pollution, and countries must take steps to adapt to and mitigate their adverse effects.

That ruling came a month after Europe’s highest human rights court said that countries must better protect their people from the consequences of climate change, in a landmark judgment that could have implications across the continent.

The ICJ’s host country of The Netherlands made history when a court ruled in 2015 that protection from the potentially devastating effects of climate change is a human right and that the government has a duty to protect its citizens. The judgment was upheld in 2019 by the Dutch Supreme Court.

Mexico City — It’s been called the closest the world has ever come to a vaccine against the AIDS virus.

The twice-yearly shot was 100% effective in preventing HIV infections in a study of women, and results published Wednesday show it worked nearly as well in men.

Drugmaker Gilead said it will allow cheap, generic versions to be sold in 120 poor countries with high HIV rates — mostly in Africa, Southeast Asia and the Caribbean. But it has excluded nearly all of Latin America, where rates are far lower but increasing, sparking concern the world is missing a critical opportunity to stop the disease.

“This is so far superior to any other prevention method we have, that it’s unprecedented,” said Winnie Byanyima, executive director of UNAIDS. She credited Gilead for developing the drug but said the world’s ability to stop AIDS hinges on its use in at-risk countries.

In a report issued to mark World AIDS Day on Sunday, UNAIDS said that the number of AIDS death last year — an estimated 630,000 — was at its lowest since peaking in 2004, suggesting the world is now at “a historic crossroads” and has a chance to end the epidemic.

The drug called lenacapavir is already sold under the brand name Sunlenca to treat HIV infections in the U.S., Canada, Europe and elsewhere. The company plans to seek authorization soon for Sunlenca to be used for HIV prevention.

While there are other ways to guard against infection, like condoms, daily pills, vaginal rings and bi-monthly shots, experts say the Gilead twice-yearly shots would be particularly useful for marginalized people often fearful of seeking care, including gay men, sex workers and young women.

“It would be a miracle for these groups because it means they just have to show up twice a year at a clinic and then they’re protected,” said UNAIDS’ Byanyima.

Such was the case for Luis Ruvalcaba, a 32-year-old man in Guadalajara, Mexico, who participated in the latest published study. He said he was afraid to ask for the daily prevention pills provided by the government, fearing he would be discriminated against as a gay man. Because he took part in the study, he’ll continue to receive the shots for at least another year.

“In Latin American countries, there is still a lot of stigma; patients are ashamed to ask for the pills,” said Dr. Alma Minerva Pérez, who recruited and enrolled a dozen study volunteers at a private research center in Guadalajara.

How widely available the shots will be in Mexico through the country’s health care system isn’t yet known. Health officials declined to comment on any plans to buy Sunlenca for its citizens; daily pills to prevent HIV were made freely available via the country’s public health system in 2021.

“If the possibility of using generics has opened, I have faith that Mexico can join,” said Pérez.

Byanyima said other countries besides Mexico that took part in the research were also excluded from the generics deal, including Brazil, Peru and Argentina. “To now deny them that drug is unconscionable.” she said.

In a statement, Gilead said it has “an ongoing commitment to helping enable access to HIV prevention and treatment options where the need is the greatest.” Among the 120 countries eligible for generic version are 18 mostly African countries that comprise 70% of the world’s HIV burden.

The drugmaker said it is also working on establishing “fast, efficient pathways to reach all people who need or want lenacapavir for HIV prevention.”

On Thursday, 15 advocacy groups in Peru, Argentina, Ecuador, Chile, Guatemala and Colombia wrote to Gilead, asking for generic Sunlenca to be made available in Latin America, citing the “alarming” inequity in access to new HIV prevention tools while infection rates were rising.

While countries including Norway, France, Spain and the United States have paid more than $40,000 per year for Sunlenca, experts have calculated it could be produced for as little as $40 per treatment once generic production expands to cover 10 million people.

Dr. Chris Beyrer, director of the Global Health Institute at Duke University, said it will be enormously useful to have Sunlenca available in the hardest-hit countries in Africa and Asia. But he said the rising HIV rates among groups including gay men and transgender populations constituted “a public health emergency” in Latin America.

Hannya Danielle Torres, a 30-year-old trans woman and artist who was in the Sunlenca study in Mexico, said she hoped the government would find a way to provide the shots. “Mexico may have some of the richest people in the world but it also has some of the most vulnerable people living in extreme poverty and violence,” Torres said.

Another drugmaker, Viiv Healthcare, also left out most of Latin America when it allowed generics of its HIV prevention shot in about 90 countries. Sold as Apretude, the bi-monthly shots are about 80% to 90% effective in preventing HIV. They cost about $1,500 a year in middle-income countries, beyond what most can afford to pay.

Asia Russell, executive director of the advocacy group Health Gap, said that with more than 1 million new HIV infections globally every year, established prevention methods are not enough. She urged countries like Brazil and Mexico to issue “compulsory licenses,” a mechanism where countries suspend patents in a health crisis.

It’s a strategy some countries embraced for previous HIV treatments, including in the late 1990s and 2000s when AIDS drugs were first discovered. More recently, Colombia issued its first-ever compulsory license for the key HIV treatment Tivicay in April, without permission from its drugmaker, Viiv.

Dr. Salim Abdool Karim, an AIDS expert at South Africa’s University of KwaZulu-Natal, said he had never seen a drug that appeared to be as effective as Sunlenca in preventing HIV.

“The missing piece in the puzzle now is how we get it to everyone who needs it,” he said.

The way the dinosaurs relinquished their long dominance is well known. An asteroid struck Earth 66 million years ago, triggering a horrific mass extinction. But the way the dinosaurs — modest creatures initially — came to supremacy is less well understood.

New research that relied heavily on fossilized feces and vomit — evidence of who is eating what and who is eating whom – provides new clarity on how dinosaurs bested the competition during the Triassic Period. The study focused on a region in Poland with extensive fossils from this pivotal time.

First appearing roughly 230 million years ago, dinosaurs were at first overshadowed by other animals including large crocodile relatives — both terrestrial and semi-aquatic — and various plant-eaters including elephant-sized ones related to mammals and four-legged armored reptiles. By about 200 million years ago, dinosaurs reigned, their main competitors extinct.

“We approached the rise of dinosaurs in a completely novel way. We analyzed feeding evidence to deduce the ecological role of dinosaurs across their first 30 million years of evolution,” said paleontologist Martin Qvarnström of Uppsala University in Sweden, lead author of the study published Wednesday in the journal Nature.

The earliest dinosaurs and close relatives were opportunists, eating foods including bugs, fish and insects. Subsequently, larger and more specialized dinosaur predators evolved along with herbivorous dinosaurs apparently better adapted than competitors to exploit new plants that arose when the climate became more humid.

Feces fossils are called coprolites. Vomit fossils are called regurgitates. Together they are called bromalites. So why study this stuff? By examining undigested food — plants and prey — in bromalites, researchers can discern feeding patterns of various species and reconstruct an ecosystem’s food webs.

Hundreds of bromalites were examined, primarily coprolites.

“We studied over 100 kilograms of fossilized feces,” said study senior author Grzegorz Niedźwiedzki, a paleontologist and geologist at Uppsala University and the Polish Geological Institute.

How can researchers tell who left the feces or vomit? Skeletal fossils and footprints showed what animals were present at a given time. And the researchers deduced who produced a given coprolite based on factors including its size and shape, the type of undigested food and the nature of the digestive systems of living relatives of these extinct animals.

Take, for example, the 6-meter four-legged meat-eater Polonosuchus, a type of reptile called a rauisuchian that was related to crocs and was an apex predator alongside the early dinosaurs.

“We know that today’s crocodiles and alligators digest food for a long time and thoroughly. In their feces, undigested bones are very rarely found. Such coprolites — large, sausage-shaped, with highly digested mass — we found in a site where bones of Polonosuchus were also found,” Niedźwiedzki said.

“In contrast, in sites where there were bones and tracks of predatory dinosaurs, we found coprolites containing a lot of undigested remains. Some of them are full of pieces of bones, fish remains, and there are also teeth. You can see that all this passed through the digestive tract quickly and was not digested in the crocodile way,” Niedźwiedzki added.

Early members of the dinosaur evolutionary lineage were omnivorous, like 2-meter Silesaurus.

“The first dinosaur relative in the area, Silesaurus, was an opportunistic little thing that ate bugs, fish and plants. Some of the insects were amazingly well preserved,” Qvarnström said.

Big herbivorous and carnivorous dinosaurs began appearing late in the Triassic, which ended 201 million years ago.

Environmental changes linked to Earth’s increased volcanic activity precipitated a wider range of plants that ever-larger herbivorous dinosaurs exploited. This proliferation of big plant-eating dinosaurs encouraged the evolution of larger carnivorous dinosaurs.

The large non-dinosaur meat-eaters disappeared before the start of the subsequent Jurassic Period, completing the transition to dinosaur dominion. By 200 million years ago, meat-eating dinosaurs 8 meters long were present, alongside plant-eating dinosaurs 10 meters long.

Smok, a 6-meter strong-jawed carnivorous dinosaur relative, lived about 210 million years ago. Coprolites showed Smok’s predilection for bone-crushing, obtaining nutritious marrow in a feeding trait associated with much later dinosaurs such as Tyrannosaurus.

The coprolites of herbivorous dinosaurs offered surprises.

“Another interesting and very mysterious discovery was the finding of geochemical signals in the coprolites from burnt plant remains, as well as pieces of charcoal. Did the dinosaurs eat charcoal from burnt plants? Ferns, whose remains are in coprolites, may be toxic, and the charcoal may have neutralized these toxins,” Niedzwiedzki added.
