23.8" Apatosaurus Dorsal Vertebra With Stand - Colorado

Apatosaurus is a genus of large sauropod dinosaurs in the diplodocid family. They could have reached lengths of 80-90 feet and lived approximately 150 million years ago, between the Jurassic and Cretaceous periods. Fossils have almost entirely been recovered from the Morrison Formation of Colorado, Wyoming, New Mexico, Oklahoma, and Utah. The cervical vertebrae of Apatosaurus are less elongated and more heavily constructed than those of Diplodocus, another diplodocid found in the same formation. Leg bones are also much stockier despite their longer length, implying that Apatosaurus was a more robust animal than Diplodocus.
