Suuwassea is a primitive form of dinosaur species and was found in North America and South America. This dinosaur species is believed to have developed characteristics similar to clades of diplodocids and dicreaosaurids. It is even called the new diplodocoid sauropod dinosaur from the Upper Jurassic era.

These dinosaur fossils recovered are huge in size and can be categorized as large herbivore dinosaurs. They were described by Harris and Dodson in 2004. This North American land dinosaur had a herbivorous diet and mostly fed on low-lying ferns, small grasses, green plants, and shrubs.

Despite their huge size, Suuwassea is still not categorized among the largest dinosaurs in the world. So you can imagine how big the dinosaurs were from this Jurassic strata!
