Atoposauridae is a family of crocodile-like archosaurs belonging to Neosuchia.

[1] The majority of the family are known from Late Jurassic to Early Cretaceous marine deposits in France, Portugal, and Bavaria in southern Germany.

[2][3][4] The discovery of the genus Aprosuchus, however, extends the duration of the lineage to the end of the Cretaceous in Romania.
