Newly Discovered Egyptian Carnivore Named after Anubis, Ancient Egyptian God of Underworld

Hyaenodonts preceded modern terrestrial carnivores in Africa and also lived in Europe, Asia, and North America. Some were tree-dwelling; others were terrestrial. The Afro-Arabian hyaenodont records are the oldest, making them key to understanding the evolution of these extinct meat-eaters.

Analysis of Egyptian fossils has identified a new species of extinct carnivorous mammals called hyaenodonts, according to a study published April 19, 2017 in the open-access journal PLOS ONE by Matthew Borths from Ohio University, United States of America, and Erik Seiffert from University of Southern California, United States of America.

The authors of the present study characterized 34 million-year-old Egyptian fossils of a new skunk-sized species of hyaenodont. They named it Masrasector nananubis, the species name referring to Anubis, the canine-headed Egyptian god associated with the afterlife. This hyaenodont was a teratodontine, a carnivorous clade that has been difficult to align with other lineages due to poorly known cranial anatomy. The fossils of the new hyaenodont are the most complete known remains of a teratodontine from the Paleogene Period, and include largely complete skulls, jaws and limb bones.

Based on the morphology of the new hyaenodont’s bones, the researchers concluded that teratodontines are a close sister group of Hyainailourinae, one of two major hyaenodont clades that were hypercarnivorous, eating mostly meat. Comparison of the limb bones with those of other meat-eating mammals suggests that the new species was terrestrial and moved fast. The researchers state that the fossils of this new species will inform all future explorations of hyaenodont evolution and ecological diversity.

“Hyaenodonts were the the top predators in Africa after the extinction of the dinosaurs,” says Borths. “This new species is associated with a dozen specimens, including skulls and arm bones, which means we can explore what it ate, how it moved, and consider why these carnivorous mammals died off as the relatives of dogs, cats, and hyenas moved into Africa.”

    This was my dog, back in the day. I called him, “Chiquetet”, meaning, “the seeker of wisdom”. It was a title my peers once attributed to me, during my 16,000 year reign as king of Atlantis…

    He pee’d on Set’s feet one day, and that’s when he became extinct. Set turned into a beastly red hippopotamus, and devoured my Chiquetet whole. That’s why I advised Horus in the art of manifesting the “winged disk”, and instructed him on how he could use it to defeat Set, that rat bastard.
