Saurostomus

Saurostomus is an extinct genus of prehistoric bony fish that lived during the early Toarcian stage of the Early Jurassic epoch.

Palaeoecology

Fossils of Saurostomus esocinus containing coleoid gladii in their oesophagus have shown that the species fed on coleoids belonging to the species Teudopsis bollensis and on indeterminate loligosepiines.
