Pterosphenus is an extinct genus of marine snake of the Eocene period.[1][2]
Classification
Pterosphenus belong to the Palaeophiid snakes, a clade which includes all snakes outside of blind and thread snakes. Its closest relative is Palaeophis, of which both belong to the subfamily Palaeopheinae.
Palaeoenvironment and Palaeoecology
A marine ocean dweller, Pterosphenus lived in the shallow seas of the future eastern US, such as Texas, Louisiana, Mississippi, and Arkansas, up north to New Jersey.
It is certain that Pterosphenus would have encountered basal cetaceans like Zygorhiza and Basilosaurus, though its likely a mixed of niche partitioning and living in different areas in the case of Basilosaurus would prevent competition between the species.
