”Häpnadsväckande” fynd av sabeltandat kattdjurForskare har upptäckt en sedan länge utdöd katt av släktet Homotherium, även känd som sabeltandad tiger, som mumifierats i minst 35 000 år i Sibiriens permafrost. Fyndet är det första i sitt slag och vad det kan berätta om evolutionen gör paleontologer mållösa.

En vetenskaplig artikel om fyndet:
Mummy of a juvenile sabre-toothed cat Homotherium latidens from the Upper Pleistocene of SiberiaThe frozen mummy of the large felid cub was found in the Upper Pleistocene permafrost on the Badyarikha River (Indigirka River basin) in the northeast of Yakutia, Russia. The study of the specimen appearance showed its significant differences from a modern lion cub of similar age (three weeks) in the unusual shape of the muzzle with a large mouth opening and small ears, the very massive neck region, the elongated forelimbs, and the dark coat color. Tomographic analysis of the mummy skull revealed the features characteristic of Machairodontinae and of the genus Homotherium. For the first time in the history of paleontology, the appearance of an extinct mammal that has no analogues in the modern fauna has been studied.
