Akhnatenavus is an extinct genus of hyainailourine hyaenodont that inhabited the continent of Afro-Arabia during the Priabonian and Rupelian stages of the Eocene and Oligocene epochs.
Distribution The species Akhnatenavus nefertiticyon is known from Quarry L-41 of the Jebel Qatrani Formation of Egypt, a fossil site dating to the terminus of the Priabonian stage. The type species of the genus, Akhnatenavus leptognathus, is known from Quarry A, a highly fossiliferous site dating to the Early Oligocene stratigraphically located in the same geologic formation.
Palaeobiology
Palaeoecology The maxillary molars of A. nefertiticyon, characterised by a tall, piercing paracone, display an extreme specialisation for hypercarnivory, and this hyainailourid thus likely fed exclusively on meat.
