The Hoofed Predators

[Polar]

Since Sarkastodon was around ~750 to 800 kilograms, and A.simus and A.angustidens being the largest carnivores in existence (till now, maybe matched with the Pleistocene Polar Bear), shouldn't the average weight for the two ursids meet at more than 800 kilograms on average? I always thought both short-faced bear species and the oxyaenid were the same weight?

Once, I was told that the biggest A.angustidens specimen was ~975 kg or about 2150 pounds, almost 100 pounds less than the largest bear ever found, the Kotzebue Polar Bear Giant.

This could possibly mean that the Pleistocene polar bears and maybe some near-modern polar bears were/ still are the largest mammalian carnivores in existance. Reply
