The Seismosaurus was a large dinosaur that measured about 43 meters long, 6 meters tall and approximately 50 tons of weight, is believed to have lived in the Upper Cretaceous about 120 million years ago and is perhaps one of the longest animals that have lived on our planet. His nose was on the tip of his head and he had cylindrical teeth only on the front of his jaw, the front legs were shorter than the hind legs and we could say that they were very similar to those of an elephant, with 5 fingers. On his thumb he had a claw, which he most likely used for protection.
Its legs were true miracles of nature as they were equipped to support a great weight and also gave great mobility to its long neck and its large tail, which incidentally used as a whip to protect itself. Despite all this it did not move as slowly as you might think because of its weight, which was similar to that of 4 elephants, perhaps that’s why its name means reptilian earthquake. There are many debates about its size was twice as long as a Diplodocus, although they are still not quite sure if the Seismosaurus is not a kind of Diplodocus, the latest research suggests that it is a completely different dinosaur. He lived in what is now New Mexico and mostly in North America.
The discovery of the Seismosaurus was very important, it was found relatively recently in 1979 in New Mexico. These massive bones were found almost by accident by hikers passing by. At first there was much confusion as to which dinosaur the remains belonged to until 1985 when they were identified as part of a new Sauropod. It was a great find especially considering the length and magnitude of the bones, once the experts calculated it they were convinced they had found one of the largest dinosaurs ever seen.
The Seismosaurus were herbivores, which means that they only ate plants, because of their large size this was only possible during the period in which they lived as the heat and humidity made the plants grow quickly. His teeth were perfect for pulling foliage from plants mostly because he needed to eat a lot of food each day to keep his incredibly large body functioning, believed to eat about a ton of plants a day. He would most likely swallow whole leaves without much chewing and like other herbivores he would swallow some stones and keep them in his stomach to help crush all the leaves he ate, these stones are called gastrophy.
Its main food would be coniferous, because it believes that its neck was so long and flexible that it did not require much effort to eat leaves that were completely out of reach of other dinosaurs and also had the ability to rise on its hind legs to reach even higher branches reaching the top of a building of more than 5 floors.
In addition to its impressive size, its neck and its impressive tail are the two most impressive and special features. He kept his neck more or less parallel to the floor, but it was so long that he could surely get his whole neck into the forest without having to go in completely, so his body was out of the mass of trees and only with his head in it could he eat practically anything he wanted. Now his tail was as long as the extension of the rest of his body, that is to say that his neck and torso were the same size as his tail, it began thick and ended very thin. It was also its most effective dense mechanism, as it used it as a whip beating its predators, which in addition to being extremely powerful also made a loud noise, there are studies that say it could even reach some animals on the fly.
Although it is an impressive dinosaur it is not very deep-rooted in popular culture and there are still some discussions about whether it is a Seismosaurus or simply a large specimen of another species so it has not been widely represented in popular culture. But according to his description many can identify him as part of the first Jurassic Park film.
