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!

The pronunciation of the generic name Suuwassea is very easy and can be pronounced 'soo-wah-see-ah'. The word Suuwassea means 'ancient thunder'.
The Suuwassea is a form of large herbivore dinosaur that clade within the Dinosauria, Saurischia, Sauropodomorpha, Sauropoda. They belong to the family of Dicraeosauridae and the genus Suuwassea. These dinosaurs' scientific name is Suuwassea emilieae. These dinosaurs were very primitive and the fossil remains recovered are of a partial Suuwassea skeleton, which included partial vertebral and limb bones. Their fossils were not recovered together but in a number of expeditions between 1999-2000. In 2004, Peter Dodson and J.D. Harris described this ancient primitive form of basal dinosaur.
The sauropods Suuwassea roamed the world during the Upper Jurassic period.
The Sauropoda dinosaurs, Suuwassea emilieae, became extinct around 145 million years ago.
Suuwassea remains were recovered from the Upper Jurassic Morrison Formation of southern Montana, USA. There is evidence of them being around the seawater resources in the north, but more remains have been found in the south, which makes them appear as basal diplodocid sauropod dinosaurs. The Morrison Formation is located in the southern Carbon Country of Montana in America.
According to the strata, these ancient herbivores were acquainted with living in both dry and wet areas. However, from the number of fossils recovered of their partial skulls and other body parts, these sauropods were more accustomed to living in dry climatic regions. It is also thought through some fossil remains that they lived near the Middle Jurassic Sundance Sea.
There is no exact information available regarding their group size, but most of the sauropods live in mixed-age groups, including juveniles and adults.
The Suuwassea lived around 145 million years ago. They lived in the Upper Jurassic strata period and lived until the Late Tithonian age.
Most sauropods are believed to reproduce by mating and laying eggs. It is assumed that these dinosaurs dug big holes in the ground and hid their eggs for safety from predators, but there is no specific information available in the context of these ancient thunder species.
The Suuwassea is a new diplodocid sauropod dinosaur from the Upper Jurassic Morrison Formation of Montana, USA. These sauropods were distinguished by their skull and axial skeleton, which were closely related in character to the clades of Diplodocid and Dicraeosaurid. Though Suuwassea is very primitive, it has similarities with two other dinosaur species.
The exact number of bones in these Suuwassea dinosaur fossils from North American land has not been evaluated and is unknown to the world.
There is no specific information available in regard to their communication, but most sauropods are believed to communicate using their vocals. They used to make different sounds in different situations.
The Suuwassea, as described by Harris and Dodson, was 46-49 ft (14-14.9 m) in length.
The exact speed of these Suuwassea sauropods is unknown.
The Suuwassea weighed around 5.4 tons (5,400 kg).
The male and the female of these species do not have any specific names and are known by their generic names.
The babies of Suuwassea are called hatchlings.
These dinosaurs were herbivores and they fed on low vegetation such as shrubs, ferns, and green plants.
Like most of the other dinosaurs, there is not much information available regarding how aggressive these sauropods were.
These Suuwassea are believed to be long-necked, small-headed, and long-tailed dinosaurs. According to Montana USA Acta Palaeontologica, the fossil of shoulder blades measured around 43 in (109 cm) and the rib was 53 in (135 cm). They are also believed to have a single hole in their skull, which is still a mystery to many scientists.
This new diplodocoid sauropod dinosaur was found in the ground of the Morrison Formation of Montana USA. They lived near the Middle Jurassic Sundance Sea.
It is assumed that these species did not have strong teeth in comparison to other sauropods because their skull roofing lacked the rostral end of the frontals, basipterygoid process, and parasphenoid rostrum.
The word Suuwassea means 'ancient thunder'. The root 'Suu' means 'thunder' and 'wassa' means 'ancient'. Therefore, it is sometimes referred to as the thunder lizard, which is often used for sauropods.
