When sharks and crocodiles ate dinosaurs
-
24-02-2018 8:37pm#1Paper describes a femur from a large (Gallimimus size) ornithomimosaur previously unidentified from eastern North America with shark and crocodile bite marks.

This is from the latest Cretaceous, so the crocodile bite marks could not come from known dinosaur-eater Deinosuchus. However, the paper does mention two crocodile species from that time and region (Borealosuchus and Thoracosaurus), in the same size range as today's largest crocodiles. A specimen of Thoracosaurus apparently reached 7 or 8 meters long.
