Eofelis is an extinct genus of small nimravid (false saber-toothed cats).

Dinictis is a genus of the Nimravidae, an extinct family of feliform mammalian carnivores, also known as "false saber-toothed cats".

The Nimravidae, sometimes known as false saber-toothed cats, is an extinct family of mammalian carnivores that was endemic to North America, Europe, and Asia.

The Nimravidae is a family in the Carnivora.

Nimravids were saber-toothed cat-like animals of the family Nimravidae.

It is the type genus of Nimravidae, Nimravinae.

Physically, Nimravidae resembled the Smilodon (which would not evolve until many millions of years later).

Unlike extant Feliformia, the Nimravidae had a different bone structure in the small bones of the ear.

The Nimravidae are the oldest, entering the landscape around 42 mya and becoming extinct by 7.2 mya.

Nimravidae was named by American paleontologist Edward Drinker Cope in 1880.

Although not "true cats" in the Felidae family, Nimravidae are considered to be a sister taxon to felids.

Despite its scientific name Nimravides does not belong to the Nimravidae, but belongs to the family Felidae.

Previously classified as a subfamily of Nimravidae, the barbourofelids have recently been reassigned to their own distinct family Barbourofelidae.

It was assigned to Felidae by Carroll (1988), but later, it was then later placed within Nimravidae.

Dinictis is a genus of the Nimravidae, an extinct family of feliform mammalian carnivores, also known as "false saber-toothed cats".

The Nimravidae, sometimes known as false saber-toothed cats, is an extinct family of mammalian carnivores that was endemic to North America, Europe, and Asia.

Other superficially cat-like mammals, such as the marsupial sabertooth Thylacosmilus or the Nimravidae, are not included in Felidae despite superficial similarities.

The extinct (-) families as reflected in the taxa chart at right are the least problematic in terms of their relationship with extant feliforms (with the most problematic being Nimravidae).

Most extinct cat-like animals, once regarded as members of the Felidae, later turned out to be members of related, but distinct, families: the "false sabretooths" Nimravidae and Barbourofelidae.

Besides the machairodonts, saber-toothed predators also arose in Nimravidae, Barbourofelidae, Creodonta (Machaeroidinae) and even in a group of sparassodont metatherians (Thylacosmilidae).

Barbourofelidae was previously classified as a subfamily of the extinct Nimravidae, but is now thought to be taxonomically closer to the Felidae than to the Nimravidae.

An example from the fossil record would be a specimen of Nimravidae, an extinct branch of carnivores in the mammalian evolutionary tree, if said specimen came from Europe in the Miocene epoch.

The Nimravidae are sometimes seen as the most basal of all feliforms and the first to split from the others, but there is a possibility that Nimravidae might not even belong within the order, and therefore its position as a clade within Carnivora is currently unstable.
