This is a Diplodocus, my second favorite dinosaur. It's a sauropod from the Late Jurassic Period. It is found in North America.

Allosaurus is my third favorite dinosaur, being a large therapod, living in North America in the Late Jurassic Period.

This a Plateosaurus, a prosauropod that lived in the Late Triassic Period.

This huge sauropod is a Brachiosaurus.

My favorite horned dinosaur, this is Torosaurus.

This is a Quetzalcoatlus. I have this under dinosaur pictures, but it is not a dinosaur, but rather a Pterosaur, which are not dinosaurs.Quetzalcoatlus was the largest Pterosaur, which made it the largest flying animal ever discovered.
