Late Jurassic, 155-150 million years ago
Supersaurus was a genus of sauropod dinosaur that lived in North America during the Late Jurassic period, about 155 to 150 million years ago. The name “Supersaurus” means “super lizard” in reference to its large size.
Supersaurus was one of the largest dinosaurs to have ever lived, with some estimates suggesting it could have reached lengths of up to 34 meters (112 feet) and weighed as much as 40 metric tons. Its long neck and tail, as well as its relatively small head, are typical of sauropods.
Supersaurus is known from a few partial skeletons and numerous bones that have been attributed to the genus. Based on the available fossil evidence, it is believed that Supersaurus was a herbivore that fed on vegetation, using its long neck to reach high branches and its peg-like teeth to strip leaves from branches.
Supersaurus is an important dinosaur for understanding sauropod evolution and the diversity of Late Jurassic dinosaurs in North America. Its fossils have been found in Colorado, Wyoming, and Utah, and its remains are housed in several museums around the world.
