Sharks eating mosasaurs, dead or alive?
Geology; morphology; mosasaurs; netherlands; Platecarpus; predation; Prognathodon; scavenging; sharks; Tylosaurus
Shark bite marks on mosasaur bones abound in the fossil record. Here we review examples from Kansas (USA) and the Maastrichtian type area (SE Netherlands, NE Belgium), and discuss whether they represent scavenging and/or predation. Some bite marks are most likely the result of scavenging. On the other hand, evidence of heating and the presence of a shark tooth in an infected abscess confirm that sharks also actively hunted living mosasaurs.

Cretaceous; fracture; Geology; mosasaurs; netherlands; Pathology; Prognathodon; stress; The Netherlands
Two unusual bumps occur on the internal surface of a rib of the marine reptile Prognathodon saturator from the Upper Cretaceous (Maastrichtian) of Maastricht, The Netherlands. These bumps are interpreted as stress fractures, possibly related to agonistic behaviour.
