''Machaeroides'' ("dagger-like") is a genus of sabre-toothed predatory mammal that lived during the Eocene (56 to 34 mya). Its fossils were found in the U.S. state of Wyoming. ==Description== Either 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. ''M. eothen'' weighed an estimated 10–14 kg, thus matching in size a smallish Staffordshire Terrier. ''M. simpsoni'' was smaller.(Egi 2001)
