Perhaps one of the most famous prehistoric mammals, and the best known saber-toothed cat, the Smilodon was more robustly built than any extant cat, with particularly well-developed forelimbs and exceptionally long upper canines. Its jaw had a bigger gape than that of modern cats and its upper canines were slender and fragile, being adapted for precision killing. Smilodon populator from South America is perhaps the largest known felid at 220 to 400 kg (490 to 880 lb) in weight and 120 cm (47 in) in height. The coat pattern of Smilodon is unknown, but it has been artistically restored with plain or spotted patterns.
This restoration of S. populator with plain coat was painted in 1903 by Charles Robert Knight (October 21, 1874 in Brooklyn – April 15, 1953 in Manhattan) the American artist best known for his influential paintings of dinosaurs and other prehistoric animals. Photo: wikipedia
