Dinaelurus
Template:Short description Template:Speciesbox
Dinaelurus is a genus of the Nimravidae, an extinct family of feliform mammalian carnivores, also known as "false saber-toothed cats". Assigned to the subfamily Nimravinae, Dinaelurus was endemic to North America during the Oligocene epoch (32.6—27.2 mya), existing for approximately 5.4 million years.[1] Including supplementary materials
Taxonomy
Dinaelurus was named by George Francis Eaton in 1922, with a single species, Dinaelurus crassus. It was assigned to Nimravinae by Flynn and Galiano in 1982.[2][3] One specimen was found in the John Day Formation in Oregon.
Description
Dinaelurus had a skull extremely broad for its length and had conical teeth; it exhibited little or no development of sabertooth features and had more rounded cheek teeth with no serrated ridges. It had a relatively gracile skeleton[4] and may have had digitigrade feet.[5] It is believed that Dinaelurus was a cursorial predator that ran down its prey. This is suggested by the nimravid's short face[4] and large nostrils, similar to those of a cheetah, which is also a cursorial predator.[5]
