Genera

Percrocutidae is an extinct family of hyaenid feliform carnivores endemic to Asia, Africa, and Southern Europe from the Middle Miocene through the Pliocene, existing for about 8 million years.[1]

The first percrocutids are known from the middle Miocene of Europe and western Asia and belonged to the genus Percrocuta. Percrocuta already had large premolars, but did not carry such a massive bite as the later form Dinocrocuta, from the later Miocene.[2] Originally, these carnivores were placed with the hyenas in the family Hyaenidae. As of 2013, most scientists considered the Percrocutidae to be a distinct family - although usually as sister-taxa/immediate outgroup to Hyaenidae.[3] Sometimes it was placed with the family Stenoplesictidae into the superfamily Stenoplesictoidea. However, studies in the 2020s placed Dinocrocuta and Percrocuta as true hyaenids, invalidating the family Percrocutidae.[4]

Taxonomy & Evolution

[edit]

Taxonomic History

[edit]

Percrocuta was first considered as a side-branch outside of Hyaenidae by Thenius in 1966.[5] It was later named as a different subfamily, Percrocutinae, of Hyaenidae in 1976, and at that time was proposed to include Percrocuta, Adcrocuta eximia, and Allohyaena kadici.[6] Dinocrocuta was elevated from a subgenus to a full genus in 1988.[7]

The family Percrocutidae was formally elevated in 1991, to include the genera Percrocuta, Dinocrocuta, Belbus and Allohyaena.[8]

Later studies have suggested that Belbus and Allohyaena are true hyaenids and not percrocutids.[9]

The list follows McKenna and Bell's Classification of Mammals for prehistoric genera (1997).[10] In contrast to McKenna and Bell's classification, they are not included as a subfamily into the Hyaenidae but as a separate family Percrocutidae.
