Researchers uncovered Brazil's biggest dinosaur ever, and it had been right in front of them for 60 years

Over 66 million years ago, a 25-meter long plant-eating beast roamed Brazil. The Austroposeidon magnificus is the largest-known dinosaur ever to have lived there, and its remains have just been $4 - in a storage cupboard.

The creature was originally found by renowned Brazilian paleontologist Llewellyn Ivor Price in 1953, but only a few parts of its fossilized spine remained. These were tidied away into storage at Rio's Museum of Earth Sciences and forgotten about until this month, over 60 years later.

Museum director Diogenes de Almeida Campos agrees that six decades is rather a long time to realise the value of your fossils. Campos explained to Business Insider that in the 1950s, Price and his assistants were unfortunately held back by the high cost of research.

Even now, there are only 10 serious dinosaur experts in Brazil, and it look several years to gather the funds and students to start up a laboratory.

Once the laboratory was in place, the team studied the Austroposeidon magnificus, which belonged to the Titanosaur group of dinosaurs that had huge bodies, long necks and small heads. They lived during the Cretaceous period in areas that now exist in South America, Africa, Antarctica, and Australia.

Only part of the huge dinosaur was found, the researchers say, because the rest of it was probably carried off and eaten by scavenger dinosaurs; a rather unceremonious end.

"When these animals die, it's a huge new source of meat. So all the hunters, the carnivores ate this creature," Campos said.

"After, came smaller animals and nothing was left over. Anything that did remain, the beetles and the spiders and the ants finished, and when there was just bones, the bacteria came. Finally, the remains sank into the lagoon."
