On the genera Thryptodus, Pseudothryptodus and Paranogmius, marine fishes (Teleostei, Tselfatiiformes) from the Upper Cretaceous of the United States, Egypt and Libya

BELGIAN JOURNAL OF ZOOLOGY, 133(2):163-173.

The osteology of three marine Upper Cretaceous teleosts, Thryptodus and Pseudothryptodus, from the U.S.A., and Paranogmius, from Egypt and libya, is studied. These genera belong to the order Tselfatiiformes. Thryptodus and Pseudothryptodus are valid genera quite different from Bananogmius, another tselfatiiform fish with which they are often synonymized. Within the Tselfatiiformes, Thryptodus appears more specially related to Plethodus and less closely to Martinichthys. Pseudothryptodus is also related to Thryptodus but differs from this genus by its snout architecture less specialized. Paranogmius is another valid genus, characterized more particularly by the presence of a subtemporal fossa on the neurocranium, a primitive structure already lost by all other Tselfatiiformes, and of an anteriorly enlarged vomer.
