America bottleneck cheetah dating genetic
Speculators suggest that these three cats could have co-existed in a way similar to what the cheetah, leopard, and lion do in Africa today.
Trumani is recent history by comparison, dating back to as late as only twenty thousand years ago.
The bones are the remains of the giant cheetah, Acinonyx pardinensis.
The giant cheetah was as tall as a modern lion, but not nearly as bulky as a lion.
Smaller cheetah fossils found in southern and eastern Africa date back to nearly the same time period.
This situation could be similar to the tiger today, where we find a variety of tiger subspecies that vary significantly in size and coat type.
The rumor mill tells of a third lesser known cat called Miracinonyx studeri which lived in North America at the same time as Truman, but details are thin.
Or on the other hand, its extinction might have cleared the way for these other cats to move in from elsewhere.
Slightly later in time we see another variety called Acinonyx intermedius, which was smaller than the giant cheetah, but still larger than the African cheetah.
