Reptilian menagerie exposed, in yet another bizarre crocodilian.

A middle Mesozoic marine crocodilian skull discovered in the Andean foothills of Argentina, exhibits a rather unusual short face. Its massive teeth are supported by a round maxilla and dentary, reminiscent of later mosasaurs, which dominated the late Mesozoic oceans. Although not suggested by the researchers, this unusual skull morphology may likely have been an adaptation to preying on ammonoids, which first appeared in significant numbers at roughly the same period of time.
