newest episode of Common Descent is about saber teeth!

They cover everything from Smilodon to Nimravids to Gorgonopsians to fanged deer (although not Hoplitomeryx)! Even Uintatherium gets a mention. Covers recent research on why Smilodon's canines would have been visible when the mouth was closed, while Homotherium's canines would have been concealed when the mouth was closed.

This weeks #Lego #FossilFriday is #Homotherium

In 1826, Reverend John MacEnery found Pleistocene aged canine teeth in a cave near Devon.

In 1846, Richard Owen described those first fossils as Machairodus latidens,

In 1890, while reviewing the material, Emilio Fabrini proposed the name Homotherium, a subgenus of Machairodus.

Between 1918 and 1976 several more species of Homotherium were named

In 2014, a review recognized only one species of Homotherium in Eurasia, synonymizing the rest.

Mummified #SaberToothed Kitten Emerges in #Siberia
The #Homotherium cub was preserved in Siberian #permafrost with its fur and flesh intact.
Using CT scans to examine cub’s bones, Dr. Lopatin and colleagues confirmed the 37,000-year-old mummy was a Homotherium, a rangy, lion-size cat with long forelimbs and heavy shoulders. The species was the last of the saber-toothed cats, which occupied a branch on the tree of life distinct from modern #felines.

NatureMummy of a juvenile sabre-toothed cat Homotherium latidens from the Upper Pleistocene of Siberia - Scientific ReportsThe 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.
