Range of Metailurus based on fossil record

Metailurus is a genus of saber-toothed cat in the family Felidae, and belonging to the tribe Metailurini, which occurred in North America, Eurasia and Africa from the Miocene to the Middle Pleistocene. [1] [2] [3]

Contents

History and taxonomy

The genus Metailurus was described by Zdansky in 1924 for the two species Metailurus major and Metailurus minor. [4]

Metailurus mongoliensis was described in 1939. [5]

Metailurus boodon was described in 1948. [6]

Metailurus hengduanshanensis was described in 1996. [7]

Metailurus ultimus was described in 2014. [8]

Metailurus minor was reassigned to the felid genus Yoshi in 2015. [9]

Description

The canines of Metailurus are longer than those of even the clouded leopard, but significantly shorter than true saber teeth, and more conical than bladed. [10] A partial skeleton found in the Turolian site of Kerassia 1 consists of the jawbone, the anterior and posterior limb bone elements, and some sternal bones and some vertebrae. This is the most complete known of the species. Its dental material is comparative to those specimens from Pikermi, Chomateri, and China. The presence of elongated posterior limbs indicate that it had developed jumping skills. [11]

<i>Proailurus</i> Extinct genus of carnivores

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.

<i>Pseudaelurus</i> Extinct genus of carnivores

Pseudaelurus is a prehistoric cat that lived in Europe, Asia and North America in the Miocene between approximately twenty and eight million years ago. It is considered to be a paraphyletic grade ancestral to living felines and pantherines as well as the extinct machairodonts (saber-tooths), and is a successor to Proailurus. It originated from Eurasia and was the first cat to reach North America, when it entered the continent at about 18.5 Ma ending a 'cat-gap' of 7 million years. The slender proportions of the animal, together with its short, viverrid-like legs, suggest that it may have been an agile climber of trees.

<i>Machairodus</i> Extinct genus of carnivores

Machairodus is a genus of large machairodont or ''saber-toothed cat'' that lived in Africa, Eurasia and North America during the late Miocene. It is the animal from which the subfamily Machairodontinae gets its name and has since become a wastebasket taxon over the years as many genera of sabertooth cat have been and are still occasionally lumped into it.

<i>Dinofelis</i> Extinct genus of carnivores

Dinofelis is an extinct genus of machairodontine, usually classified in the tribe Metailurini. It was widespread in Europe, Asia, Africa and North America from 5 million to about 1.2 million years ago. Fossils very similar to Dinofelis from Lothagam range back to around 8 million years ago, in the Late Miocene.

<i>Homotherium</i> Extinct genus of carnivores

Homotherium is an extinct genus of machairodontine scimitar-toothed cat that inhabited North America, South America, Eurasia, and Africa during the Pliocene and Pleistocene epochs from around 4 million to 12,000 years ago. In comparison to Smilodon, the canines of Homotherium were shorter, and it was probably adapted to running down rather than ambushing prey.

<span class="mw-page-title-main">Nimravidae</span> Extinct family of mammals in the order Carnivora

Nimravidae is an extinct family of carnivorans, sometimes known as false saber-toothed cats, whose fossils are found in North America and Eurasia. Not considered to belong to the true cats, the nimravids are generally considered closely related and classified as a distinct family in the suborder Feliformia. Fossils have been dated from the Middle Eocene through the Late Miocene epochs, spanning about 33.2 million years.

<span class="mw-page-title-main">Machairodontinae</span> Extinct subfamily of carnivores

Machairodontinae is an extinct subfamily of carnivoran mammals of the family Felidae. They were found in Asia, Africa, North America, South America, and Europe from the Miocene to the Pleistocene, living from about 16 million until about 11,000 years ago.

Smilodontini is an extinct tribe within the Machairodontinae or "saber-toothed cat" subfamily of the Felidae. The tribe is also known as the "dirk-toothed cats". They were endemic to South America, North America, Europe, Asia, and Africa during the Miocene to Pleistocene, from 10.3 mya—11,000 years ago, existing for approximately 10.3 million years.

<i>Megantereon</i> Extinct genus of saber-toothed cat from North America, Eurasia and Africa

Megantereon was a genus of prehistoric machairodontine saber-toothed cat that lived in North America, Eurasia, and Africa. It is closely related to and possibly the ancestor of Smilodon.

<i>Adelphailurus</i> Extinct genus of felid

Adelphailurus is an extinct genus of metailurin machairodontine (saber-toothed) cat that inhabited western North America during the middle Pliocene. It is monotypic, containing only the species Adelphailurus kansensis.

<span class="mw-page-title-main">Barbourofelidae</span> Extinct family of feliform carnivorans

Barbourofelidae is an extinct family of carnivorans of the suborder Feliformia, sometimes known as false saber-toothed cats, that lived in North America, Eurasia and Africa during the Miocene epoch and existed for about 7.9 million years. Thought to be an independent lineage from the Nimravidae and Machairodontinae, which had all attained elongated canines, recent research argues that it may be a subfamily of the Nimravidae, extending its biochronological range into the Miocene, although this issue is not yet fully resolved.

<i>Nimravides</i> Extinct genus of carnivores

Nimravides is a genus of extinct saber-toothed cats that lived in North America during the Late Miocene, between 10.3 and 5.332 Ma. Despite its scientific name, Nimravides does not belong to the Nimravidae, but is a true cat belonging to the family Felidae.

<i>Sansanosmilus</i> Extinct genus of carnivores

Sansanosmilus is an extinct genus of carnivorous mammal of the family Barbourofelidae endemic to Europe, which lived during the Miocene, 13.6—11.1 mya, existing for approximately 2.5 million years.

<i>Amphimachairodus</i> Extinct genus of carnivores

Amphimachairodus is an extinct genus of large machairodonts. It is also a member of the tribe Homotherini within Machairodontinae and is most closely related to such species as Xenosmilus, Homotherium itself, and Nimravides. It inhabited Eurasia, Northern Africa and North America during the late Miocene epoch.

Yoshi is an extinct genus of machairodontine sabertooth cat in the tribe Metailurini. Its fossils were described from Turolian deposits from the Miocene epoch of the Balkan Peninsula in 2014 and specimens from China once thought to belong to Metailurus. The name comes from that of the lead author's pet cat. It has been described as potentially being synonymous with Metailurus, though this is difficult to confirm at present. The type specimen is a skull that bears remarkable similarities with the modern cheetah. Yoshi is intermediate in size between a lynx and cougar, and based on several as-yet unpublished skeletons, may have had a similar lifestyle to the cheetah, being better built for speed and fast pursuit than most other machairodonts, which were more suited to ambush and hunting large, relatively slow moving animals.

Styriofelis is an extinct genus of Felidae known from the Miocene of Europe.

Namafelis is an extinct genus of felids that lived in what is now Namibia during the Early Miocene. It contains a single species, Namafelis minor. Closely related to Diamantofelis, it is of “Pseudaelurus-grade”, and therefore a rather basal member of the cat family.
