the Prehistoric Ocean: Illustrations of Dinosaurs

This rather dramatic picture was done especially for my poster presentation at the 1999 Society of Vertebrate Paleontology meeting in Denver.  It shows a large Cretoxyrhina mantelli shark taking a bite out of a juvenile Tylosaurus.  While we are unsure if these sharks attacked live mosasaurs, or scavenged their carcasses, feeding by sharks on mosasaurs is supported by a lot of fossil evidence. See the Ginsu Shark, Parts and Pieces, and A Moment in Time.
