Scrawls, sketches, and chicken scratches - a doodle thread

Post things you've drawn! To get started, here's a bunch of dinosaurs and other critters I doodled during my preliminary zoology lab (because it was about learning to not trip over and break your neck in the lab itself, but that's typical for a first-lab-of-the-semester):


Some horseshoe crabs and proto-archaeopterii.


Pterandon, Parasaurolophus and some other things. I have no idea how pterosaur feet work; we only studied the wings last semester.


Box-dinosaur, a shitty sketch where I tried to explain to my friend how bird's feet worked, a sauropod, and a weird probably-XX-inspired amphibian predator. With webby fairy wings and nubby little spikes for some reason.


Uh... there's definitely a Hadrosaurus and a Styracosaurus in the bottom left, but I dunno what the stegosaur is. Probably inspired by a Toujangosaurus. And a pachycephalosaur just hooning along.
