Oligocene feliforms

Proailurus is an extinct felid genus that lived in Europe and Asia approximately 25–30.8 million years ago in the Late Oligocene and Miocene. Fossils have been found in Mongolia, Germany, and Spain.

Eusmilus ('true sabre') is a prehistoric genus of nimravid that lived in Europe and North America during the Late Eocene to Early Oligocene epochs (34.7–29.5 mya).

Dinictis 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, Dinictis was endemic to North America from the Late Eocene to Early Oligocene epochs (35.7—29.5 million years ago), existing for about .

Hoplophoneus (Greek: "murder" (phonos), "weapon" (hoplo)) is an extinct genus of saber-toothed carnivoran belonging to the family Nimravidae, sometimes known as false saber-toothed cats. The titular member of the subfamily Hoplophoninae, it is closely related to nimravids such as Eusmilus and Nanosmilus. Hoplophoneus lived in North America and Asia during the Late Eocene to Early Oligocene epochs from 35.7 to 30.5 mya, existing for approximately . Including supplementary materials The genus currently consists of three named species: H. oharri, H. occidentalis, and H. primaveus.

Nimravus is an extinct genus of "false" saber-toothed cat that lived in North America and Eurasia during the Eocene and Oligocene epochs 35.3—27.1 mya, existing for approximately . Not closely related to true saber-toothed cats, they evolved a similar form through parallel evolution. Fossils have been uncovered from western U.S. from Oregon to Southern California and Nebraska, and also from Eurasia from France to Mongolia.

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 .'' Including supplementary materials''

Pogonodon is an extinct genus of cat-like nimravid endemic to North America during the Oligocene.

Stenoplesictidae is the name of a polyphyletic family of extinct civet-like feliforms.

Eofelis is an extinct genus of small nimravid (false saber-toothed cats). They were catlike creatures that evolved in parallel with true cats but are not a part of the true cat lineage and have left no living descendants. The genus was first described in 1938 by Miklos Kretzoi.

Stenogale is an extinct genus of carnivorans whose fossils are found in France, Germany, and Switzerland.

Quercylurus is an extinct nimravid carnivora (or "false sabre-toothed cat") from the Early to Late Oligocene of France and Spain. Its fossils were found in Early Oligocene strata in Quercy. It is known with only one species Quercylurus major. Q. major was one of the largest nimravids ever known, as its fossils suggest it was similar in size to the modern-day lion.

Stenoplesictis is an extinct genus of enigmatic aeluroid carnivoran restricted to western Europe that lived during the Oligocene epoch. It was named by Henri Filhol in 1880 and contains the type species S. cayluxi as well as two other species, S. minor and S. crocheti. While several additional species from Asia and Africa had been assigned to it, S. muhoronii is the only species of Stenoplesictis needing a reassignment to another genus.

Dinailurictis is an extinct nimravid carnivoran (or "false sabre-toothed cat") belonging to the subfamily Nimravinae. It was named in 1922, with subsequent material being recovered from Early to Late Oligocene deposits across France and Spain.

Palaeogale is an extinct genus of carnivorous mammal known from the Late Eocene, Oligocene, and Early Miocene of North America, Europe, and Eastern Asia. A small carnivore often associated with the mustelids, Palaeogale might have been similar to living genets, civets, and linsangs.

Taotienimravus is an extinct genus of false saber tooth cats (Nimravinae) that lived in Eastern Asia during the middle Oligocene epoch. Currently only species in this genus is Taotienimravus songi making it a monotypic genus. Its lack of saber teeth and bone-cracking adaptations make Taotienimravus unique among Nimravidae.

Asiavorator (meaning "Asian devourer") is an extinct genus of civet-like carnivoran belonging in the family Stenoplesictidae. It was endemic to Asia and lived during the Eocene and Oligocene epochs.

Nanosmilus is a nimravid from the Oligocene (Whitneyan to Arikareean stages) of Nebraska. As a member of Feliformia, it is related to the superficially similar-appearing true cats. As such, it and nimravid genera in general are often referred to as false saber-toothed cats. No larger than a small bobcat, it is the smallest known saber-toothed mammal currently recognized by science. It is most closely related to its fellow nimravid Eusmilus.
