Extinct Creatures-- Icarosaurus (Patreon)

Our next Triassic Weirdo is Icarosaurus, a gliding relative of lizards and snakes. This particular form of gliding, where the ribs support a membrane, has actually evolved independently several times, so Icarosaurus isn't even that much of a weirdo. Coelurosauravus came before them, and Icarosaurus was a member of a whole group of these little gliding reptiles that lived during the Triassic. And now, in modern times, we have the entire Draco genus of gliding lizards. So it seems this is a pretty efficient gliding structure!

I probably made this guy a little too chunky, especially when you look at how skinny Dracos are, but oh well!!
