These giant dinosaurs started the American Museum of Natural History’s collection

The world’s largest dinosaur is getting some company.

The American Museum of Natural History has brought out dozens of never-before-seen fossils for a new exhibit, Sauropods at the Museum. The towering veggiesaurus with a long neck and tail (you probably know it from “The Land Before Time”) is among the giants of the Jurassic Period, 150 million years ago.

It also has the distinction of being the dinosaur find that began the museum’s collection back in 1897. The partial skeletons, including a pelvis and femur, are displayed on racks as if they were still in the museum’s storage rooms (which hold nearly 5 million fossils), along with images from the expedition that discovered them in Wyoming as well as ongoing digs.

The exhibit replaces five fossils from the even more gigantic Titanosaur, a sauropod-like species found in Patagonia, Argentina, in 2014. But don’t worry – the 122-foot-long Titanosaur skeleton in the Miriam and Ira D. Wallach Orientation Center will remain. It’s a model constructed using 3D scans of the bones, which are too fragile to be mounted.
