A skull discovered in the Egyptian desert belong to a never - before - see vertex predator that roamed portion of North Africa and the Arabian Peninsula about 30 million yr ago , scientists say .
The skull was unearthed in the Jebel Qatrani Formation , about 60 air mile ( 100 kilometre ) from Cairo . Now , scientists have identified it as a young species , calledBastetodon syrtos , in a study published Feb. 17 in theJournal of Vertebrate Paleontology .
The newfound hypercarnivore speciesBastetodon syrtoslived about 30 million years ago.
WhenB. syrtoslived , the region would have been breed by a lush forest . It is a phallus of an nonextant order of mammals known as hyaenodonts , which thrived from around 66 million to 5.3 million age ago . It was probable a " hypercarnivore , " scientists say — a carnivore with a dieting of more than 70 % meat .

" For day , the team meticulously excavated layers of rock and roll dating back around 30 million eld , " tip authorShorouq Al - Ashqar , a researcher at Mansoura University and the American University in Cairo , said in astatement .

" Just as we were about to reason out our workplace , a squad member spot something noteworthy — a set of large teeth sticking out of the ground , " she say . " His excited vociferation brought the team together , mark the get-go of an extraordinary discovery : a closely complete skull of an ancient apex carnivore , a dreaming for any vertebrate paleontologist . "
A elaborate examination of the skull revealed it had a curt , cat - like snout and a powerful jaw capable of dismembering prey . Unlike many of today ’s carnivores , which have specialized , plane shearing teeth , hyaenodonts likeB. syrtoshad multiple sets of blade - like tooth , meditate their hypercarnivorous diets .

The newfound skull date to 30 million years ago , when the neighborhood was surface-active agent than it is today .
Researchers examine the skull , which is still case in its protective plaster cast .
The team named the newfound genusBastetodonafterBastet , an ancint Egyptian goddess with a cat caput who is know for protection , pleasure and wreak good health .

concord to the statement , B. syrtoslikely feasted on the ancient relatives of innovative - day hippos , elephants and primates .
The discovery remind the researchers to reanalyze a grouping of lion - sizing hyaenodonts discovered in the same area over 120 years ago . These senior samples are a dissimilar metal money , but they are closely related toB. syrtos , the researchers tell . However , a few cardinal differences led them to create a new genus , Sekhmetops , to delineate these other hyaenodonts .

" The discovery ofBastetodonis a significant achievement in understanding the diversity and phylogenesis of hyaenodonts and their global distribution , " Al - Ashqar suppose .
Hyaenodonts eventually spread from Africa in multiple waves , make water it to Asia , Europe and North America . However , dramatic climate changes eventually allowed fresh carnivores to recruit the continent , and the hyaenodonts went out , making way for the ancestors of modern carnivore .
