ANOTHER ANATOMY POST! Only three vertebrate groups have successfully evolved flight: Birds, Bats, and Pterosaurs, which are NOT dinosaurs, and are an extremely diverse group of reptiles! Pterodactyl is not the only one. However, birds ARE dinosaurs. Avian dinosaurs!
Wings are not some extra structure you tack on to a creature and somehow the arms go away— they ARE arms. Think about that when you are designing creatures with wings and also giving them arms. That means your creature has six limbs.
Next anatomy post: The anatomy and evolution of DRAGONS. If you guys have any requests, feel free to send them in!
Well it’s quite important! In order to understand creature design, you must understand anatomy! Now if I receive one more comment about how I made Charizard’s wings ‘look like arms,’ I will link them to both my post and this one (which explains it much better)!
