Sauroposeidon proteles

Pronounced: Saw-row-poe-Si-den Diet: Herbivore (Plant-Eater) Name Means: "Lizard Poseidon" Length: 98 feet (30m) Height: 60 feet (19 m) Weight: 70 tons (63,500 kilos) Time: Late Jurassic/Early Cretaceous - 110 MYA

Sauroposeidon is possibly the tallest dinosaur ever. Reaching heights as high as a six-story building, this huge plant eater was related to Brachiosaurus.

What is interesting is that it lived at a time when there were very few giant sauropods left in North America - most had become extinct by the middle of the Cretaceous period.

The discovery of this huge sauropod in Oklahoma has been a great help to scientists, as not much is known about dinosaurs from this period. It is also a bit perplexing, however, as most of the giant North American sauropods had vanished by this time. Their cousins were thriving in South America, but for some reason they had, except for Sauroposeidon, gone extinct in North America and would not be seen again for tens of millions of years until the titanosaurs migrated north.
