Watch a mummified dinosaur be excavated from a rock in a mesmerizing timelapse

Paleontologists extract a mummified dinosaur from a rock in Canada, with the deceased creature believed to be completely covered in skin.

The dinosaur fossil, which was discovered in Dinosaur Provincial Park in Alberta, Canada, was first discovered by paleontologists from the University of New England and the Royal Tyrrell Museum in Drumheller in 2021, according to a museum blog.

Since then, excavation efforts have continued.

The skeleton belongs to a herbivorous species called the hadrosaur, also known as the “duck-billed dinosaur”. So far, only the animal’s tail and foot have been discovered.

Based on findings from the 2022 field season, paleontologists believe an almost complete skeleton is in the rock, due to the orientation of its tail.

And, they also think that the whole skeleton is completely covered in skin.

Time-lapse video from the Royal Tyrrell Museum shows paleontologists gradually uncovering the rare find.

Hadrosaurs were a relatively common species that lived during the Late Cretaceous, around 75 to 77 million years ago.

Royal Tyrrell Museum paleontologist and lead researcher of the specimen, Caleb Brown, said Pleasemynews that these specimens “are often called mummies”.

“Finding dinosaur skin is rare, but is more common for some types of dinosaurs than others. Duck-billed dinosaurs (hadrosaurs) are a group of dinosaurs where skin is most commonly preserved,” said he declared.

“That skin is often preserved as a few small fragments or pieces associated with the skeleton,” Brown added.

“When we’re really lucky, we find a skeleton that’s almost entirely covered in skin. Over the past 120 years, several hadrosaurs with skin have been found in Dinosaur Provincial Park.”

Brown said finding a fully preserved skeleton, as they believe, is “relatively rare” because parts of fossils are usually lost due to erosion.

“The parts of the skeleton that are exposed are covered in preserved skin. The hope is that the rest of the skeleton (the parts still in rock) are also covered in skin. If so, we might have a hadrosaur ‘mum ‘” Brown said.

This fossil probably belonged to a young dinosaur due to its small size. This will give paleontologists new insight into the growth of this species.

“Most dinosaur fossils are just bones. You can learn a lot from the bones, but there’s still a lot of anatomy missing. When the skin is preserved, you can fill in the gaps in certain details about anatomy and life. of these animals,” Brown said.

“The skin can tell us details about how the animal interacts with its environment and other dinosaurs.”

Dinosaur Provincial Park, where the fossil was discovered, is a UNESCO World Heritage Site that has been important to paleontologists for more than a century. According to the Royal Tyrrell Museum, every year paleontologists discover new discoveries at the site.
