Flying Dylanus

Flying dylanus is a pterosaur-like bat-like descendant of domestic dylanuses that evolved into flying omnivorous diurnal mammals that replaced some extinct seabirds and extinct forest/grassland birds. These mammals, depending on a species, can range from the size of a large sparrow to the size of an extinct Pteranodon, making e largest flying dylanus species the largest flying animal in the future world. They are found in almost all continents on Earth, except Antarctica, were it is still too cold for flying dylanuses to live in.

Evolution
After humans became extinct and all other sapient species/beings left Earth, many of the pet dylanuses were left to die, but broke out due to intelligence, grasping hands, and human-like sizes, they went out to fend for themselves. Many domestic dylanuses were killed off by predators or interbred with wild dylanuses, but few managed to survive and evolved to a new way of life. Some dylanuses developed tree-climbing skills and became good leapers, and over time, they developed skin membranes between their arms and legs for gliding. They then evolved thicker chests and stronger arm muscles, giving them powered flight, thus evolving into flying dylanuses, and many evolved many snouts for different purposes depending on a species.
