Problem:The size of Parasaurolophus walkeri compared to a human. As is the case with most dinosaurs, the skeleton of Parasaurolophus is incompletely known. The length of the type specimen of P. walkeri is estimated at 9.5 meters (31 ft). What environment did a parasaurolophus live in? Parasaurolophus lived along the western shore of the Western Interior Seaway. The area was a floodplain with rivers and swamps, and had distinct wet and dry seasons. Conifers were the primary trees, but other plants like ferns, ginkgoes, cycads, and flowering plants also lived there. Brachiosaurus was an unusual dinosaur that lived 155.7 million to 150.8 million years ago during the mid- to late Jurassic Period. Specimens have been found primarily in the fossil-rich Morrison Formation in North America, but the dinosaur did not resemble any of the others that roamed the region. Its long neck made it look like a giraffe, and its forelegs were longer than its hind legs. The name Brachiosaurus, in fact, means arm lizard.. When did dinosaurs live? Dinosaurs lived between about 247 and 66 million years ago, in a time known as the Mesozoic Era. This was many millions of years before the first modern humans, Homo sapiens, appeared. Scientists divide the Mesozoic Era into three periods: the Triassic, Jurassic and Cretaceous. What period did the parasaurolophus live? Parasaurolophus lived from about 76.5 to 73 million years ago. This was near the end of the Cretaceous period, the last period in the Mesozoic era. Parasaurolophus Facts. 1 Check out our Parasaurolophus facts for kids.
