There's a more in-depth look at the article
here, and the paper itself can be found
hereActually, what may surprise some people is that Apatosaurus was actually bigger and more impressive than Brontosaurus. Of the two, it seems that Brontosaurus lived slightly earlier as well. There were also a few specimens included in Apatosaurus that lie outside either genus and may deserve a new name entirely too.
All this is fascinating to experts, but as for its effect on the average person I posted the following comment on the blog from the first link:
I’m afraid that the “Brontosaurus is back!” fanfare is going to increase confusion among the general public though, especially considering the misconception that Apatosaurus was a “replacement name” for Brontosaurus. There will be people wondering why the skulls weren’t changed back*, why the skeleton in Pittsburgh is still being called Apatosaurus after the name was changed, and such.
*Apatosaurus and Brontosaurus had long been reconstructed with a big rounded head when the actual skull turned out to be smaller and flatter. This mistake has often been conflated with the naming issue in popular culture.
