There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
A lot of prehistoric species we don't have a true "average" figure for. There are usually less than a handful of worthwhile specimens that certainly cannot properly represent the entire population. For A. simus, we fortunately do have a lot of bones and the average for males was likely 700-800 kg off the top of my head, but I might be remembering wrong. There is only A. angustidens specimens, so no average can be given here. I am not aware of how many Sarkastodon specimens there are to say anything on their averages.
