But did you know that for years, this mighty dinosaur was displayed with the wrong skull? Using incomplete remains, scientists speculated that Apatosaurus was closely related to another sauropod: Camarasaurus. As a result, a similar skull to Camarasaurus was sculpted and placed atop Apatosaurus’ body (pictured), where it remained for decades. As new research emerged, this reconstruction was updated. To this day, only one Apatosaurus has ever been found with its skull attached!
