A dinosaur fossil was found with a small dinosaur in its stomach

Scientists have found a rare dinosaur fossil in Alberta, Canada.

According to relevant CBS report This is a young dinosaur carrying the remains of two young dinosaurs inside its stomach.

The discovery provides new evidence about how dinosaurs’ behavior and role in ecosystems changed as they grew, say the Canadian researchers who led the study, published Friday in the journal Science Advances.

Fewer than twenty dinosaurs have been found to have stomach contents, and most of them were herbivores, making the new discovery very rare.

The tyrannosaur meals themselves — the legs of two small, bird-like dinosaurs called Citipes elegans — were also an exceptional find, said François Therin, the Canadian paleontologist who led the study.

“They are very rare animals,” he said. “What’s really interesting is that the stomach contents are the most complete urban skeletons ever discovered,” he said.
About 75 million years ago, during the Late Cretaceous, parts of Alberta were a subtropical coastal plain on the west coast of an inland sea separating North America. Herds of dinosaurs like Parasaurolophus, horned dinosaurs like Centrosaurus, and thick-headed dinosaurs known as Pachycephalosaurs were among the many species that grazed among the palm trees and evergreen trees along the rivers, where they were hunted by the massive Gorgosaurus.

Many remains of these giants have been preserved and excavated, but the more fragile bones of smaller, younger dinosaurs are much rarer.

So there was a lot of excitement when Darren Tank, a technician from the Royal Tyrrell Museum in Drumheller, Alberta, found the bones of a baby extraterrestrial dinosaur at Dinosaur Provincial Park in 2009. At the time of its death, it was only four years old. meters – less than half the length of an adult and the size of a school bus. Researchers later estimated that he was between five and seven years old, years away from the transition to adulthood, which begins around age 11.
