Late Jurassic, 155-145 million years ago
Diplodocus, meaning “double beam,” was a giant sauropod dinosaur that lived during the Late Jurassic period, approximately 155 to 145 million years ago, in what is now western North America.
Diplodocus was a long-necked herbivorous dinosaur that could grow up to 90 feet in length and weigh up to 15 tons. Its long neck and tail, along with its relatively small head, gave it a unique and distinctive appearance.
One of the most notable features of Diplodocus was its whip-like tail, which could be used as a defensive weapon against predators. The dinosaur’s tail was also likely used for communication within its herd, with the cracking sound of the tail being heard over long distances.
Diplodocus was a quadrupedal dinosaur, meaning it walked on four legs, and had a relatively small skull and narrow jaws. It fed on a variety of vegetation, including ferns, conifers, and cycads, using its peg-like teeth to grind and chew tough plant material.
Diplodocus is one of the most well-known and studied sauropod dinosaurs, with numerous fossils having been found throughout the western United States. Its unique anatomy and relationships with other sauropods have helped scientists to better understand the evolution and ecology of this fascinating group of dinosaurs. Diplodocus remains a popular and iconic dinosaur in popular culture, and it continues to inspire awe and wonder among people of all ages.
