Acrotemnus is an extinct genus of pycnodontid ray-finned fish from various areas of the Tethys Sea that lived during the Turonian stage of the Upper Cretaceous. The genus comprises three species A. faba,[1] A. streckeri, and A. megafrendodon.[2]

Description

Acrotemnus was initially known from just the type species A. faba described by Louis Agassiz in 1843 from specimens collected in Niger.[1] However, Shimada, Portillo, and Cronin, 2021 described the specimen TxVP 43056-3 as Acrotemnus cf. A. streckeri lumping the whole genus Macropycnodon into Acrotemnus.[2]

Classification

In its description, Agassiz, 1836 recovers it as a pycnodontid.[1] Shimada, Portillo, and Cronin, 2021 retain this placement in their redescription of A. streckeri, and A. megafrendodon.[2]
