Dinosaurs!!

I've been having a dinosaur kick lately, specifically for the cretacious period, Cambrian period, and the late Permian period. My current favorite dinosaurs as of now are the Aralosaurus, a species of hadrosaur, Inostrancevia, a species of gorgonopsid, and the Utahraptor, a species of Dromaeosauridae, aka raptor. I want to draw them, but I doubt I have time to today.
