Looks as if the Brontosaurus is going to make a proper, scientific comeback, after a study found that it is in fact distinctly different from Apatosaurus. Woot! I always felt sad for old Bronty!
The scientists analysed 81 skeletons and measured around 477 anatomical traits to create a new evolutionary family tree. Statistically, two main groups emerged: one containing more slender species, such as Diplodocus, and a second containing the bulkier Apatosaurus. Within the Apatosaurus group, though, further considerable distinctions were found. Apatosaurus had a thicker neck than the original Brontosaurus specimens, and differences were seen in the shape of their shoulder blades and ankle bones, according to the PeerJ report.
“The differences we found between Brontosaurus and Apatosaurus were at least as numerous as the ones between other closely related genera, and much more than what you normally find between species,” said Roger Benson, a co-author from the University of Oxford.
