The scapula of Brontosaurus also has a rounded extension off of its edge, a characteristic unique to Brontosaurus among Apatosaurinae. The coracoids of apatosaurines have a quadratic outline in dorsal view. Sterna have been preserved in some specimens of Apatosaurus and Brontosaurus, which display an oval outline. [1]
One of traits that distinguishes Brontosaurus and Apatosaurus is the presence of a depression on the posterior face of the scapula, which the latter lacks. The scapula of Brontosaurus also has a rounded extension off of its edge, a characteristic unique to Brontosaurus among Apatosaurinae. [3]
