The 90-million-year-old find could reshape understanding of plant-eating dinosaurs in the region.

A team of paleontologists working in South America has uncovered a near-complete dinosaur skeleton, which they believe belonged to a large herbivorous species that lived approximately 90 million years ago.

The find is notable because the majority of skeletons from this period are fragmentary, making it difficult for researchers to reconstruct how such animals moved, fed and grew.

Early analysis suggests the animal may represent a previously undocumented species, though the team is cautious about confirming this until further comparisons are made with existing fossil records.

The bones will undergo detailed study over the next two years, after which the museum plans to put a reconstructed skeleton on public display.
