schwimmer and g. dent williams proposed in 1996 that "deinosuchus" may have preyed on marine turtles. "deinosuchus" would probably have used the robust, flat teeth near the back of its jaws to crush the turtle shells. the "side-necked" sea turtle "bothremys" was especially common in the eastern habitat of "deinosuchus", and several of its shells have been found with bite marks that were most likely inflicted by the giant crocodilian.
