Atoposauridae

Atoposauridae is an extinct family of neosuchian crocodyliforms, known from the Jurassic and Cretaceous of Eurasia. Characterised by their small size and their heterodont (having multiple tooth types) dentition, they are thought to have lived in terrestrial and semi-aquatic environments, and to have consumed small prey such as fish, insects and mammals. The oldest records of the group are known from the Middle Jurassic of Britain. The majority of the family are known from Late Jurassic to Early Cretaceous deposits in France, Portugal, and Bavaria in southern Germany. The discovery of the genus Aprosuchus, however, extends the duration of the lineage to the end of the Cretaceous in Romania.
