carnotaurus

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.

giganotosaurus

a theropod larger than t-rex from cretaceous argentina. probably hunted some of the huge sauropods that survived in south america into that period.

brachiosaurus

a huge sauropod from the jurassic.

psittacosaurus

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.

hypsilophodon & gallimimus

hypsilophodon on the left, gallimimus on the right.

cryptoclidus

not actually a dinosaur. but a plesiosaur, a sort of marine reptile.

sunday dinos

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.
