We are 200 million years A.D. the rays are among the most diversified vertebrates and they conquered every living environments ! And by "every" i mean really each viable living environment for species of that size. Here are some of the largest rays.
1. Pteravampirus is a genus of flying vampire ray
, but it's probably the largest of all, with a wingspan of 1m50 (5 feet) it can kill large animals by sucking their blood through the teeth under their wings. They live in the cold forest of EurAsia.
2. Pteralictis is another flying ray, but it's not a relative of Pteravampirus, less aggresive than the vampire rays it's still a predator and it uses its long tongue to eat insect such as ants.
3. We go back in the sea with Rynchobatelus, the descendant of the rajiformes, it has a long spike on the head and 2 smaller mandible-like limbs able to crush shells. They are 6m long (20 feet).
4. Balaenomimus, is a whale-like ray with baleen plates, these one is only 5m long but the largest Balaenomimus can reach up to 20m (65 feet), those huge behemots migrate among the ocean of the Post-Xenocene
5. Myliobatimimus seems familiar, it's the descendant of the myliobatiformes and didn't evolve that much.
6. Pristidus is the great white shark of the ocean, 200 million years in the future, unlike his ancestor the sawfish, it use its saw to rip the flesh off its victims and devour them. An old Pristidus would be 8m (26ft) long.
7. Batoiserpentes is a weird animal, all the snake-like rays come from the same ancestors than flying rays, they developed lungs to be able to live on the ground. They have a long poisonous spike on their tail to catch preys.
8. Pristiboa is not a descendant of the sawfish but developed a saw by an evolutionary convergence, they are able to rush into the ground to dig up small animals.
