A recent finding in the provincial Dinosaur Park allowed to discover a pterosouric fossil with a bite mark of a primitive crocodile. This discovery, which dates from 76 million years ago, offers a new perspective on the interactions between species in the Cretaceous and the food chains of the time.
A group of scientists discovered a Pterosouric fossil With one Bitired brand of a primitive crocodril in it Park provincial dinosaur of Alberta, Canada. The finding, recently made, corresponds to a Flying reptile who lived 76 million years during the Cretaceous. The fossil, a vertebra of a young pterosourio, has a Four millimeter drilling wide, which shows that crocodiles could have hunted or eaten pterosaurs at that time.
The fossilized piece, found in the Park provincial dinosaur of Albertait belongs to a youth pterosourium and presents a circular drilling of approximately four millimeters widewhich indicates that it was bitten by a crocodile that hunted or fed on carrion at that time. The revelation of this fossil is key to better understanding the life and behaviors of the beings that inhabited the earth millions of years ago.
Pterosaur
An exceptional finding in Alberta
Pterosaur fossil was a Cryodrakon Boreas young and found in an impressive state of conservation. Experts managed to confirm that the bite brand was not the result of damage during fossilization, but that it was a true bite of a primitive crocodril.
This type of fossil is Extremely weirdsince the bones of pterosaurs are Fragile and delicate, which makes the finding even more significant. The investigation was led by the Dr. Caleb Brownof the Royal Tyrrell Museum of Paleontology.

Implications on life in the Cretaceous
This discovery not only offers a vision about the diet of Primitive crocodilesbut also documents a new interaction between species in the Cretaceous. According to researchers, crocodiles occasionally hunted young pterosaurs or fed on their carrion in the region of Albertawhich shows opportunistic behavior in the fauna of that time.
In addition, it is the First evidence in North America of ancient crocodiles feeding on these gigantic flying reptiles. This finding contributes to the understanding of the Food chain in the Cretaceous and the dynamics of survival of the animals of that period.
