Patagosaurus (PAT-uh-go-sore-us)
A Middle/Late Jurassic sauropod from southeastern Argentina [for Patagonia, Argentina]. Patagosaurus reminded of Cetiosaurus, but had a different tail and different hipbones. It was built in a more "oldfashioned" way than Haplocanthosaurus, but less oldfashioned than Amygdalodon.
