Arctic Homotherium Serum by Ghirin

The saber-toothed cats were one of the major branches of the prehistoric felines.

The genus Homotherium contained lion-sized felines with laterally flattened canines, unlike the conical canines of modern cats. Homotherium fossils have been found in both Pleistocene North America (H. serum) and Eurasia (H. latidens) and these cats were probably specialists in hunting young pachyderms such as mammoths.

White variants naturally occur in todays lion and tiger populations, but such a color is usually a disadvantage. However, a pale coat might have been an advantage to populations of Homotherium living in areas with extensive snow cover (Alaska, Siberia).
