Enischorhynchus (Greek for "slender snout") is an extinct genus of prehistoric marine ray-finned fish that lived during the Late Cretaceous. It contains a single species, E. dallasensis from the late Santonian or early Campanian-aged Austin Formation of southern Texas, USA. [1] It was a member of the Plethodidae, a dominant family of nektonic fish during the mid-late Cretaceous. It shows close morphological similarities and may be related to Concavotectum and Bachea . [2] [3] It was likely an endemic of the southern Western Interior Seaway. [4]
