Albanosmilus is an extinct genus of the family Barbourofelidae.[1] It lived during Middle and Late Miocene in Eurasia and North America.[2][3]


Classification

Bryant in his 1991 considered Albanosmilusas a member of the false sabre-toothed cat family Nimravidae.[4] However, Albanosmilus was eventually considered part of the Barbourofelidae, considered a synonym of Sansanosmilus. However, by 2013 it was considered a valid genus with two species: Albanosmilus jourdani, the type species (with synonyms Albanosmilus vallesiensis, Barbourofelis vallesiensis) and Albanosmilus whitfordi (with synonyms Barbourofelis whitfordi).[2] In the recent years, some studies suggest Barbourofelidae were actually members of the Nimravidae, under the subfamily Barbourofelinae.[5][6]

Description

A. jourdani could weigh around 80–100 kg (180–220 lb), making it one of the largest members within Barbourofelidae, just behind Barbourofelis.[7] A. whitfordi is described to being smaller than the North American species of Barbourfelis.[8]

Paleobiology

Isotopic analysis suggests A. jourdani and Machairodus were specialized on different prey even if they inhabit similar habitats, they suggest the arrival of M. aphanistus may have led to the extinction of A. jourdani.[9] Coprolites likely referable to this genus were described in 2023, which may suggest that Albanosmilus was an apex predator in this locality.[10]

A. jourdani disappeared from the Iberian Peninsula around 9.1 Ma.[11]
