El Reg reports Besmirched brontosaurus brought back into being by brilliant Britons' bone boffinry breakthrough

In 1879, [...] paleontologist Othniel Charles Marsh named a collection of bones a brontosaurus, or Thunder Lizard, and described a massive herbivore with a long neck and tail that wandered across the plains of what is now America.

[...]within a couple of decades, the existence of the Thunder Lizard was called into question and the scientific community decided that the stumbled-upon brontosaurus was just an adolescent apatosaurus. There then followed a 100-year campaign to expunge the word brontosaurus from textbooks, but the name proved just too popular.

Now, a study looking at the largest range of fossils of the genus has shown that the brontosaurus was a distinct genus. While the dino does have strong similarities to the apatosaurus, there are enough differences to separate the two, the study's authors concluded.

[...]The initial argument for the non-existence of the brontosaurus was down to its sacrum bones, which link the tail to the base of the spine. The first Thunder Lizard found had five of these, compared to the apatosaurus' three, but it was assumed that the brontosaurus bones were young and would have merged together to form these three bones.

But as more and more specimens were found, this theory started to look a little off. That was reinforced by other fossil evidence, so the new study turned to statistics to find out what was going on.

[...]It's not a done deal yet however. The International Commission on Zoological Nomenclature will have to rule on the matter.
