Paleontologists are restoring the good name of Brontosaurus more than a century after it was deemed scientifically invalid and the famous dinosaur was reclassified as another genus called Apatosaurus.

They unveiled on Tuesday an exhaustive analysis of Brontosaurus remains, first unearthed in the 1870s, and those of closely related dinosaurs, determining that the immense, long-necked plant-eater was not an Apatosaurus and deserved its old name back.

Paleontologist Emanuel Tschopp of Portugal's Universidade Nova de Lisboa cited important anatomical differences, including Apatosaurus possessing a wider neck than Brontosaurus and being even more massively built.
