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.

The pleistocene bison "Blue Babe" was not a large bison specimen, check this out:

The lion-like Panthera spelaea from Alaska were no larger than the modern African lion, with a maximum skull lenght of about 38 cm.

They were estimated to 300 kg in the past.How much is the new estimate?

The source is from the book "Megafauna: Giant Beasts of Pleistocene South America" of Fariña et al. (2013).
This is a specimen from the Cincinnati Museum of Natural History & Science, a large one:

Finally, a comparison between bison species, the text doesn't say that it is a scale, so just take it as reference of the body characteristics:

Beautiful illustration,I love it.IMO Mauricio Anton is the best paleoartist.

In fact, it depend of the crono-subspecies. For the old Cromerian "lions" normally clasified as Panthera fossilis, the estimation is up to 400 kg, those cats were huge! But for the most "modern" steppe lions clasiffied as Panthera spelaea, the weights were probably on the same line as modern lions - Panthera leo and tigers - Panthera tigris, based in they bones and skulls, which are about 200-270 kg, maybe up to 300 kg in the largest specimens (bones are very robust). The transitional form, like the male of the San River, was between those two extrems and about the same size of the large America "lions" Panthera atrox, with weights of probably up to 350 kg in the larger males.
Depiction of bison latifrons running fleeing from an ursid...
" Bison latifrons (also known as the giant bison or long-horned bison) is an extinct species of bison that lived in North America during the Pleistocene epoch. This species of bison was the largest and heaviest to ever live in North America. B. latifrons reached a shoulder height of over 2 meters and may have weighed up to 1,250 kg. The horns of B. latifrons measured as great as 213 centimeters from tip to tip, compared with only 66 cm in modern American Bison. "
