another south american theropod. carnotaurus was bizarre in that it had a pair of bull-like horns atop its head and tiny, stubby arms (even stubbier than a tyrannosaur). the function of the horns is not presently known, and can only be speculated at.

psittacosaurus, a small ceratopsian (horned dinosaur). recently, due to impressions found with fossils, it's been found that it had a row of spines or feathers on its tail. whether this was for display or acted like a porcupine's spines isn't known.

sorry i didn't get to post yesterday, so here are two dinos. the green one is a therizinosaurus, a bizarre theropod from the late cretaceous. most theropods, like t-rex or deinonychus, were carnivores, but the therizinosaurs were gigantic herbivores. they're sort of like a big goose and a giraffe had a baby. they also had some pretty sick looking claws on their front limbs. the blue one is a pachycephalosaurus, another late cretaceous dinosaur, who had a thick dome of bone on top of his head. we're not sure if they butted heads like rams, or used them as self defence, or just for display.

i did a stegosaurus, and two animals that, while popularly thought of as dinosaurs, are not. dimetrodon was a pelycosaur, a synapsid more closely related to mammals than to true reptiles. pteranodon was a pterosaur (pterodactyl), who, like the dinosaurs, belonged to a group called the archosaurs (dinosaurs and birds, crocodilians, pterosaurs).
