Biggest Dinosaur Ever? New 'Titanosaur' Fossil Could Be a Record Breaker

05/19/2014 at 12:00 PM EDT

New fossils discovered in Argentina in 2011 debuted Saturday at the country's Museo Paleontologico Egidio Feruglio. And given that the creatures they belonged to were 130 feet long and up to 180,000 pounds, they're in the running for the largest dinosaur ever, with a name appropriate for the station: Titanosaurs.

"It's like two trucks with a trailer each, one in front of the other, and the weight of 14 elephants together," Jose Luis Carballido, a dinosaur specialist at the Argentinian museum, told CNN.

But anyone expecting a new kind of super-predator will be disappointed: Titanosaurs were herbivores. Scientists assumed their seven specimens (pieced together from 200 fossils found in Patagonia) became stuck in the mud and perished from dehydration or starvation.

Sometimes size isn't everything.
