Abstract

A new ornithocheirid pterosaur, Akharhynchus martilli gen. et. sp. nov. from the Ifezouane Formation, Kem Kem Group of Morocco is described, based on a well-preserved anterior rostrum fragment. It is assigned to a new genus based on one autapomorphy and a unique combination of synapomorphies, including the following: the medial rims of the first alveoli pair contact each other and the first alveoli pair are 50% smaller than the second alveoli pair. Comparative anatomy and a phylogenetic analysis demonstrate that Akharhynchus has affinities with Tropeognathus within Tropeognathinae.
