Acinonyx aicha

Acinonyx aicha is an extinct felid species belonging to the genus Acinonyx. It was first described in 1997 based on fossils from the Pliocene of Morocco.[1]

Discovery and naming

A.aicha was discovered in the Ahl al Oughlam site in Morocco, from the late Pliocene.[1] It is only known from the holotype AaO-1456 which is a complete and disfigured skull.[1] The specific name is derived from a cheetah called Ayesha from TinTin, specifically from The Red Sea Sharks[1]

Description

The cranial lacks a strong convexity compared to other species, such as the cheetah, and the zygomatic arch also suggest a normal temporal fossa.[1] The skull also includes a very concave glenoid cavity, which is limited by a string rim.[1] The upper teeth are longer than A.pardensis and longer relative to the width, and the anterior tubercle is much less developed compared to the posterior, especially compared to other species.[1]
