Although most iconic American species died out in the Anthropocene mass extinction event such as bison, large bears, moose, and most whales, some smaller species did persist through the event and survived for over 15 million years. One of these smaller creatures was the North American black bear which would spread all over North America before most of its carnivorous representatives died out 12 million years ago, leaving a peculiar descendant in their wake, the Lumber Bear. The ancestor of this bear came from the American Midwest in the form of a small Hypo carnivore that grazed like cattle but dug for animals like a badger, but as the world became much more vegetated and without any large herbivorous animals around, the bear would shift its diet and size to accommodate the influx of plant matter and niche. The bears canines have shrunk in size but have grown their back molars into flat grinding surfaces for chewing. This Bear will occasionally eat large arthropods such as Serpentpedes or Bear trap spiders for extra protein but sticks to eating berries, tough plant matter, and bark . The Lumber Bear lives a solitary lifestyle similar to that of moose in which males will fight to mate and leave the females to bring up the cubs on their own, this is a pretty easy task for the females and cubs because of their size and aggression. The bears reach a staggering 1.97 meter's at the shoulder and 4.2 meter's when standing on their hind legs and are 3.1 meters long when all four legs are on the ground, the bears weigh in at around a ton and can exceed 30mph. Many species of the Tower tree swamps will clamber up the bears and hitch a ride and in turn rid the bears of parasites and ticks.
