Dinosaur That Lived During Jurassic Period

Seismosaurus was a sauropod and one of the largest animal ever to walk the earth, whose intelligence was very low in comparison with other dinosaurs.

It is said to be lived during the Late Jurassic Period, 156 million years ago.


It measured half a football field in length, is the longest dinosaur to date.

It is believed that this dinosaur may have lived in herds, but until more evidence is found, such as fossilized foot prints or several skeletons in the same place, this is just a speculation.

So far, paleontologist have only found one Seismosaurus skeleton, but a lot has been learned from it.

This skeleton was more or less complete.

When scientists uncovered the remains of the creature's stomach area they gathered a pile of about 250 gastroliths.

Most of these stones were about 2 inches in diameter and aided this large herbivore by crushing plant material into a pulp.


Seismosaurus had nostrils on top of its head.

It had a small head, and peg-like teeth sitting in front of its jaws.

Its forelimbs were shorter than its hindlimbs.

Its feet had five toes, and one of these was a thumb clawed.

It had a long wip-like tail which may have been used to lash out at a predator with.

Seismosaurus was a long neck dinosaur, bigger even than its close relative, Diplodocus.
