ichthyosaur

A rare fossil discovery reveals a tooth embedded in an ichthyosaur’s vertebra, likely from a giant pliosaurid attack 160 million years ago. The find provides evidence of a predator-prey interaction between marine reptiles during the Mesozoic era.

An orca-sized ichthyosaur fossil reveals evidence of its last meal, which was a pterosaur. The fossil also indicates the ichthyosaur was subsequently eaten by a larger marine predator.
