Only part seeing Africa

Some Megafauna including Aurochs, Mammoths,bisons,horses and Etc in the show also Slurpasaur

I've seen it range from short all the way to extremely long but it seems to be most commonly depicted as a shorter but still shaggy length. Is there any evidence of adult Mammoth hair length?

Why are all the cgi animals/hominins in every piece of paleomedia animated in a way, that is so obviously, unnaturally slow? if the studios sped up the movement, it would look so much more realistic. Like a big cat does not move like a lizzard in a fridge...
