Oxyaenidae
Oxyaenidae ("sharp hyenas") is a family of extinct carnivorous placental mammals. Traditionally classified in order Creodonta, this group is now classified in its own order Oxyaenodonta ("sharp tooth hyenas") within clade Pan-Carnivora in mirorder Ferae. The group contains four subfamilies comprising fourteen genera. Oxyaenids were the first to appear during the late Paleocene in North America, while smaller radiations of oxyaenids in Europe and Asia occurred during the Eocene. Etymology The name of order Oxyaenodonta comes , name of hyena genus ''Hyaena'' and . The name of family Oxyaenidae comes , name of hyena genus ''Hyaena'' and taxonomic suffix ":wikt:-idae#Suffix, -idae". Description They were superficially cat-like mammals that plantigrade, walked on flat feet, in contrast to modern cats, which digitigrade, walk and run on their toes. Anatomically, characteristic features include a short, broad skull, deep jaws, and teeth designed for crushing rather than shearing, as in ...

Diegoaelurus
''Diegoaelurus'' ("San Diego's cat") is a Extinction, extinct genus of mammals from the extinct subfamily Machaeroidinae within extinct family Oxyaenidae. This genus currently contains only one species ''Diegoaelurus vanvalkenburghae'', found in the Santiago Formation, California, Santiago Formation in California. This mammal lived during the Uintan stage of the Eocene, Middle Eocene Epoch around 46.2 to 39.7 million years ago. Etymology The name of genus ''Diegoaelurus'' comes from city San Diego and . ''Diegoaelurus vanvalkenburghae'' was named after Dr. Blaire Van Valkenburgh in honor of her research on carnivorous mammals and saber-toothed predator paleoecology. Description ''Diegoaelurus vanvalkenburghae'' was small in stature, with a size comparable to a Fossa (animal), fossa. The holotype fossils (SDSNH 38343) consists of a mandible and well preserved dentition. Its discovery has made paleontologists question whether this group's extinction was caused due to the Eocene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machaeroides
''Machaeroides'' ("dagger-like") is a genus of sabre-toothed predatory mammal that lived during the Eocene (54.9 to 46.2 mya). Its fossils were found in the U.S. state of Wyoming. Description Both species bore a passing or superficial resemblance to a very small, dog-sized saber-toothed cat. ''Machaeroides'' could be distinguished from actual saber-toothed cats by their more-elongated skulls, and their plantigrade stance. ''Machaeroides'' species are distinguished from the closely related '' Apataelurus'' by the fact that the former genus had smaller saber-teeth. Despite its small size, the genus ''Machairoides'' was well-equipped to hunt prey larger than itself, such as the small, primitive horses and rhinoceroses present at the time, as it was equipped with saber teeth and powerful forelimbs to subdue prey. ''M. eothen'' weighed an estimated , thus matching in size a small Staffordshire Terrier. ''M. simpsoni'' was probably smaller. Taxonomic placement Its position within the ...

Saber-toothed Cat
Machairodontinae is an extinct subfamily of carnivoran mammals of the family Felidae (true cats). They were found in Asia, Africa, North America, South America, and Europe from the Miocene to the Pleistocene, living from about 16 million until about 11,000 years ago. The Machairodontinae contain many of the extinct predators commonly known as "saber-toothed cats", including the famed genus ''Smilodon'', as well as other cats with only minor increases in the size and length of their maxillary canines. The name means "dagger-tooth", from Greek μάχαιρα (''machaira''), sword. Sometimes, other carnivorous mammals with elongated teeth are also called saber-toothed cats, although they do not belong to the felids. Besides the machairodonts, other saber-toothed predators also arose in the nimravids, barbourofelids, machaeroidines, hyaenodonts and even in two groups of metatherians (the thylacosmilid sparassodonts and the deltatheroideans).

Tytthaena
''Tytthaena'' ("little hyena") is an extinct genus of oxyaenids from subfamily Tytthaeninae. It lived during the late Paleocene to early Eocene in North America. Two species are known, ''T. parrisi'' and ''T. lichna''. Description ''Tytthaena'' is the smallest oxyaenid known. Morphologically, it resembles ''Oxyaena''. It can be distinguished from other oxyaenids by its size and dentition. Its molars were narrow, with elongate talonids.P. D. Gingerich. (1980.)
