A small dinosaur leg seen in southwestern North Dakota was probably torn from the animal’s body the same day a giant asteroid struck Earth and completely wiped out the dinosaurs.

The team that found the model said thescelosaurus ate plant legs. According to them, the fossil, found in the affected skin, was probably 66 million years old when the seismic event was completed.

The fish were also seen breathing in the rubbish when it hit the ground, according to the coral turtle researchers that were pierced by a tree, the remnants of the small fat particles and their burrows, the Skin of the horned triceratops, the nest of the pterosaur flying into its eggs. , or a fragment from an asteroid.

The show will air on BBC One’s “Dinosaurs: The Final Day with Sir David Attenborough” on Friday. It will air in a two -hour special PBS beginning at 9 pm on May 11.

According to Robert DePalma, the University of Manchester graduate student leading the excavation, the project has helped researchers complete the game play of the day the asteroid struck Earth.

“It was like watching him play movies,” he told BBC News. “You look at the stone column, you look at the princes there, and it comes back to you that day.”

Paul Barrett of London’s Natural History Museum was not involved in the program but told BBC News there were no signs of illness or bruises on the foot.

“So the best idea we had was that this was an animal that died quickly or not,” Barrett said.

Some scholars are skeptical.

Anthony Fiorillo, a research professor at Southern Methodist University, is a specialist in taphonomy, a field of paleontology that studies the evolution of materials into fossils.

He called the leg “well -preserved,” noting that it was stuck with fossilized soft tissue that is common in dinosaur fossils.

The group has an “interesting story,” but lacks details, Fiorillo said.

“The corpse is shrinking, so it can be like the death of this animal and this leg, the flesh that holds it, is so bad that some kind of sedimentological process pulls it out of the animal. and buried 100 feet. from where the rest of the corpse was, “Fiorillo said.

Liz Freedman Fowler, an assistant professor of biological and geological sciences at Dickinson State University in North Dakota, echoed Fiorillo’s concerns.

“You can’t see what the skin looks like,” he told USA TODAY on Tuesday. “It’s one little piece like the skin, but the rest of it isn’t enough the pictures really say it.”

As for new discoveries, it’s not uncommon to see all kinds of fossils stored in one place, Fowler said. He is waiting for more information, such as maps and 3D scans of the site.

“We heard there were probably feet. We wanted to see that foot in the ground and how it slept in relation to the fish kings there. That’s right.”


Sea reptiles like fish were buried in its blubber in southern Germany 150 million years ago.
