I put here a photo of chacma baboon, largest extant baboon, when it is standing on hind legs. Even when I compare this real photo to that picture of Rom, for me this creates immediately contradiction between photo and artist´s view. This photo makes me to think, that looks like Rom has made a mistake with measurements and how to use those. I mean it looks like that he has used shoulder height on all fours when it should have been when on hind legs. And in that way he scaled these monkeys up quite a lot. Maybe I am wrong, but it would be nice to get more information if so. https://africafreak.com/chacma-baboons (05-26-2019, 02:17 PM)Shadow Wrote: @Wolverine Heh, I actually misunderstood a bit. So this which I shared was from this Rom. But that other picture, where was that gigantic looking drawing next to about 180 cm tall man was really odd looking. Anyway this picture by Roman Uchytel looks like to give quite good image, what size these prehistoric ancestors of baboons might have been compared to humans.

I am interested as to what predators, if any, that the gorilla had to contend with other than the leopard. Very curious. Well, it appears obvious that, as far as anyone here knows, ever since the existence of gorillas, the top land-based predator of the Congo basin has been the leopard. https://www.gorillas-world.com/gorilla-evolution/ The gorillas were separated from the other hominids about 7 million years ago, although some sources indicate that began to populate Africa around 11 million years ago. With the extinction of other great apes, gorillas became the largest primates in the world. A few years ago, it was thought that all gorillas belonged to a single species, and there were three subspecies, but now, the latest research concluded that there are two species: eastern gorilla (Gorilla beringei) and western gorilla (Gorilla gorilla), with two subspecies each. Both species diverged about 2 million years ago and were separated by the Congo River. *So, this would suggest that the leopard has been the apex land-based predator of the Congo basin throughout the last 7 to 11 million years.
I will add this to accompany post #18 above. https://en.wikipedia.org/wiki/Leopard#Evolution
Fossils of leopard ancestors were excavated in East Africa and South Asia, dating back to the Pleistocene between 2 and 3.5 million years ago. The modern leopard is suggested to have evolved in Africa about 0.5 to 0.8 million years ago and to have radiated across Asia about 0.2 and 0.3 million years ago. *So, it appears that for several million years, there were no large predators in the Congo basin. Until the evolution of the leopard, the great apes of Africa had no predators. |
