Apatosaurus different dinosaur individuals. Among the many notable differences are the widerand presumably strongerneck of "Apatosaurus" species compared to "B.excelsus". Other species previously assigned to "Apatosaurus", such as "Elosaurus parvus" and "Eobrontosaurus yahnahpin" were also reclassified as "Brontosaurus". Some features proposed to separate "Brontosaurus" from "Apatosaurus" include: posterior dorsal vertebrae with the centrum longer than wide; the scapula rear to the acromial edge and the distal blade being excavated; the acromial edge of the distal scapular blade bearing a rounded expansion; and the ratio of the proximodistal length to transverse breadth of the astragalus 0.55 or greater.

Wyoming Dinosaur Center on the property is from the "Something Interesting" or SI excavation site. This site presents the rare occurrence of both dinosaur trace fossils and body fossils including footprints of many Sauropods and "Allosaurus" as well as skeletal remains from "Camarasaurus, Diplodocus," and "Apatosaurus" - three of the sauropods most common in the area during the Late Jurassic. Most of the bones belong to a juvenile (30 foot long) "Camarasaurus" that was scavenged by many "Allosaurs". This is known based on the presence of both teeth and claw marks on many of the bones present as well as an abundance of
