Scientific Classification
Some scientists argue that Seismosaurus should be classified as a species of Diplodocus
  Kingdom Animalia
  Phylum Chordata
  Class Sauropsida
  Superorder Dinosauria
  Order Saurischia
  Suborder Sauropodomorpha
  Infraorder Sauropoda
  Family Diplodocidae
  Genus Seismosaurus
Seismosaurus was a massive plant-eater (herbivore) that lived in North America during the Jurassic period, between about 155 and 145 million years ago.

When initially discovered, Seismosaurus was believed to be between 130 and 170 feet (40 to 52 meters) in length, with most of its length was taken up by its very long neck and tail, but the body and head being both comparatively small. Recently however there has been discussion among scientists about Seismosaurus, firstly about whether it should be classified as a separate genus from Diplodocus, and secondly about its length - some recent estimates put its length as "only" 110 feet (33.5 meters).

Seismosaurus Facts

Here is a summary of some of the key facts about Seismosaurus:
  1. Seismosaurus was a genus of dinosaur. Some scientists have argued that Seismosaurus should be classified as a species of Diplodocus.

  2. "Seismosaurus" means "earthquake lizard" (a reference to its enormous size).

  3. Seismosaurus was a member of the Saurischia ("lizard-hipped") order of dinosaurs. What this means, is that although Seismosaurus was not closely related to lizards, it did have similarly shaped pelvic bones.

  4. Seismosaurus was a Sauropod - a member of a group of related large quadrupedal herbivorous (plant-eating) dinosaur with long necks.

  5. Seismosaurus lived between about 155 million years ago and 145 million years ago, during the Jurassic period.

  6. Seismosaurus lived in North America.

  7. Seismosaurus was a herbivore (plant-eater).

  8. Seismosaurus is thought to have been a grazer, and probably could not have raised its head very far above the ground level.

  9. Seismosaurus was possibly about 130 to 170 feet in length (40 to 52 meters). There are however some scientists who believe that Seismosaurus was actually a species of Diplodocus, and was perhaps "only" about 110 feet (33.5 meters) long.

  10. Seismosaurus weighed about 25 to 30 tons.
