Cipactlichthys

Cipactlichthys is a genus of extinct marine holostean fish from the Lower Cretaceous of Mexico, distantly related to modern bowfins.

Cipactlichthys scutatus is known from two fossils discovered in the Tlayua Formation near the town of Tepexi de Rodríguez, in Puebla, Mexico.

[1] The Tlayua Formation, is Albian (Early Cretaceous) in age, interpreted as an epicontinental marine deposit.

[1] Cipactlichthys is classified in the clade Halecomorphi due to possession of a crescent-shaped preopercle and the involvement of the symplectic bone in jaw articulation.
