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.

This topic is about the Pleistocene mega-fauna and their possible predators.
What large herbivores might the Pleistocene bears have hunted?
Order Xenarthra ( sloths and armadillos )...
Family Dasypodidea included Holmesina septentrionalis an armadillo 6 feet long and 3 feet high. One of these big guys weighed roughly 600 pounds.
Family Gliptodontidae included Glyptotherium arizonae which measured roughly 10 feet long and you may add to this length a tail 4.5 feet long. This big heavily armored herbivore weighed roughly 1 ton ( 2,000 pounds ).
Family Megalonychidae included Megalonyx jeffersonii - Megalonyx meaning "giant claw" and jeffersonii after Thomas Jefferson who greatly admired this great beast. This giant ground sloth measured roughly 10 feet long.
Family Megatheriidae was another group of giant ground sloths. Eremotherium rusconii was a huge member of this family which lived in North America. A large male could measure 20 feet long and weigh up to 6,000 pounds.
Family Mylodontidae included Paramylodon harlani, a ground sloth which could measure 12 feet long and weighed roughly 3,500 pounds.
