Fossil lungfish

Ceratodus humei in the strict sense of the species lived from the Early Cretaceous to the Paleocene.

Ceratodus humei is one of the few species of the genus Ceratodus that survived beyond the end of the Cretaceous into the Tertiary, and it was used, together with other species, to date the Jabal Umm Himar fauna to the Paleocene.

Ceratodus humei is an extinct lungfish described by Priem in 1914 and known mainly from its tooth plates.

The only Saudi record is a single tooth from the right pterygo-palatine of a large lungfish, identified as Ceratodus humei Priem 1914.
