I am a person who loves biology I love learning biology and speculative evolution is my favorite type of biology and sci-fi instead of just giving them random power or random designs there's actual origins of evolutionary paths anatomy explanations and logic and I have been wondering what would have happened if pterosaurs instead of becoming extinct what if they evolve instead of become extinct like dinosaurs and the synapsids so this is what I speculate they might look like pterosaurs would have more variety they would be bigger or smaller I mainly think that they would try to move away from the flight path for some species to get shorter and wider mouths and that they would do some other things that whales do and slowly lose the ability to fly but still keep some remnants of flight in their anatomy and I also think that they would develop thicker limbs and bodies and have more muscle mass and fat I imagine them to look like if bats and birds had a baby.

I've always wondered why vampires only bite the neck for blood I know because of major arteries but I wonder why they don't cut their victims to get to the more blood filled tissue it's kind of like how bears only eat some parts of salmon and throw the rest away
