All Todays Werewolf's Description
Fossils of these carnivorous medium-sized mammals have been found in most of Europe and North America. These creatures have often been suggested as either a social pursuit/ambush pack-hunter, a solitary pursuit/ambush predator, or just a scavenger. Their feet may or may not have claws or nails, but no one knows for sure since no similar animal exists today. They probably lived in cold snowy forests as evidenced by fossilized remains of cold-tolerant plants that have been found were werewolves have been found in. If hunters, werewolves most likely have hunted deer, sheep/goats, camels, humans, dylanuses, pigs, and some others, but may also have competed against other predators like bison, wolves, bears, cats, sharks, and vampires (especially Owari no Seraph vampires, the most common type of vampires of the Holocene-Anthropocene( for the prey in their area. Werewolves were most likely quadrupedal creatures as modern studies suggests. They probably built nests and laid eggs like today's reptiles and birds, but may have instead gave birth to live young like today's rodents. Their lifespan is unknown, but they may have live up to 100 years if cold-blooded, but may have lived for only 50-60 years if warm-blooded. It is unknown why werewolves had became extinct.
Introduction to real life North America
Since real life humans had introduced all todays werewolves to real life North America, these large carnivores of many species (amphibians, reptilian ones, avian ones, and mammalian ones) now coexist alongside formerly fictional werewolf species. Unlike werewolves, all todays werewolves don't turn humans into werewolves, and unlike their ancestors, all kinds of all todays werewolf species are now peaceful to any sapient species/beings and to dylanusids, as they adapted into human settlements and learned to tolerate human activities and among others, so they now flourish alongside formerly fictional werewolf species and are now very tame towards any sapient species.
