Geosaurinae is a subfamily of metriorhynchid crocodyliforms from the Middle Jurassic to the Early Cretaceous (Bathonian - Aptian) of Europe, North America and South America.[1][2][3] Named by Richard Lydekker, in 1889, it contains the metriorhynchids Suchodus, Purranisaurus, Neptunidraco, Tyrannoneustes, Torvoneustes, Dakosaurus, Geosaurus and Plesiosuchus. The last five taxa form a tribe within Geosaurinae, the Geosaurini. Geosaurinae is one of two subfamilies of Metriorhynchidae, the other being Metriorhynchinae.[4]
These marine reptiles were widespread during the Late Jurassic and Early Cretaceous, their fossilized remains are being frequently found on various places around the world.[5]
