Recognizable nimravid fossils date from the late Eocene (37 Mya), from the Chadronian White River Formation at Flagstaff Rim, Wyoming, to the late Miocene (5 Mya). Nimravid diversity appears to have peaked about 28 Mya. A 2021 study has shown that a sizeable number of species developed feline-like morphologies in addition to saber-toothed taxa ...
Nimravus is an extinct genus of "false" saber-toothed cat that lived in North America, Asia and Europe during the late Eocene and Oligocene epochs 35.3—26.3 mya, [1] existing for approximately .
Quercylurus major is an extinct, cat-like nimravid carnivora (or "false sabre-toothed cat") from the early Oligocene of France. Its fossils were found in Early Oligocene strata in Quercy. Q. major was possibly the largest nimravid ever known, as its fossils suggest it was similar in size to the modern-day lion. [1]
Species of Hyaenodon have been shown to have successfully preyed on other large carnivores of their time, including a nimravid ("false sabertooth cat"), according to analysis of tooth puncture marks on a fossil Dinictis skull found in North Dakota.
Nimravidae cladogram. The Nimravinae are a subfamily of the Nimravidae, an extinct family of feliform mammalian carnivores sometimes known as false saber-toothed cats.They were endemic to North America, Europe, and Asia from the Middle Eocene through the Late Miocene epochs (Bartonian through Tortonian stages, 40.4—7.2 mya), spanning about 1]
Hoplophoneus, though not a true cat, was similar to cats in outward appearance, though with a robust body and shorter legs.The largest known specimen is estimated to have weighed 160 kg (350 lb), similar to a large jaguar.
Life reconstruction of E. adelos. Most Eusmilus species had a long body and were about as tall as a leopard, though the species E. adelos was similar in size to a small lion, and thus was the largest of the holplophonine nimravids, reaching the weight of nearly 111 kg [2] Eusmilus had developed long saber teeth and looked like a saber-toothed cat, but was actually a so-called 'false saber ...
The species Pseudaelurus thinobates and Pseudaelurus pedionomus were both described by James Reid MacDonald in 1948. [ 6 ] [ 7 ] In 1975, Martin and Schultz reassigned Machairodus catacopsis to Nimravides and suggested that N. thinobates was a junior synonym of the former species. [ 8 ]
