American lion
The American lion (Panthera atrox), also known as the "North American lion", or "American cave lion", is an extinct pantherine cat that lived in North America during the Pleistocene epoch and the early Holocene epoch, about 340,000 to 11,000 years ago. Its fossils have been excavated from Alaska to Mexico. Genetic analysis has shown that the American lion and the Late Pleistocene Eurasian cave lion (Panthera spelaea) are sister lineages. It was about 25% larger than the modern lion, making it one of the largest known felids. The American lion is estimated to have measured 1.6 to 2.5 m (5 ft 3 in to 8 ft 2 in) from the tip of the nose to the base of the tail and stood 1.2 m (3.9 ft) at the shoulder. Thus, it was smaller than its contemporary competitor, the giant short-faced bear, which was the largest carnivoran of North America at the time, and larger than the saber-toothed cat, Smilodon fatalis, which may have weighed up to 280 kg (620 lb). In 2008, the American lion was estimated to weigh up to 420 kg (930 lb). A study in 2009 showed an average weight of 256 kg (564 lb) for males and 351 kg (774 lb) for the largest specimen analyzed. A study in 2012 estimated a range of 235–523 kg (518–1,153 pounds) for males and 175–365 kg (386–805 pounds) for females, which suggests that the lion was heavier than Smilodon.
Ngandong tiger
Panthera tigris soloensis, known as the Ngandong tiger, is an extinct subspecies of the modern tiger species. It inhabited the Sundaland region of Indonesia during the Pleistocene epoch. The few remains of the Ngandong tiger suggest that it would have been about the size of a modern Bengal tiger. However, given the size of other remains, it may have been larger than a modern tiger. A large male could have weighed up to 470 kg (1,040 lb), in which case, it would have been heavier than the largest extant tiger subspecies, and similar in size to Smilodon and Panthera atrox, rendering it, along with these two other cats, among the largest felids known to have lived.
