Paleontologists have discovered the fossil remains of a “titanosaur” in Argentina, which they say may belong to the largest dinosaur ever.

The paleontologists found the fossil of the 94-million-year-old dinosaur in thick, sedimentary deposits, and say they now have bones from its pelvis and the parts of its skeleton that helped connect the giant’s legs to its body.

“It is a huge dinosaur, but we expect to find much more of the skeleton in future field trips, so we’ll have the possibility to address with confidence how really big it was,” Alejandro Otero, a paleontologist with Argentina’s Museo de La Plata, told CNN.

Otero and several colleagues published a paper in the journal, Cretaceous Research, outlining the dino bones.
