Rhyniognatha is an extinct genus of arthropods and is often considered the oldest flying insect. Named after the place where it was found, Rhynie in Scotland, and the Greek word "gnathos" (the pine).
It is said to add an original style of creature, using a species almost forgotten in ARK: Insects! It's also a way to make the sky more dangerous, even if you've already tamed a flying mount! Plus, once it's tamed, it becomes a mount in the endgame! This creature was suggested by Zichfried.
