Dinosaur Fossil of a Titanosaur Discovered in Argentina May Belong to the Largest Land Animal Ever

Dinosaur fossils could belong to the world’s largest ever creature

Discovering dinosaur fossils is always a great event as they have been extinct for so long, the only thing the world knows about them is thanks to science. Patagonia is known for its amazing scenery, but paleontologists also consider it a hub for fossils as major discoveries happened there over the years.

In a recent article published by the Cretaceous Research, evidence was presented of a new find in Argentina, at the Neuquen Province which is in the northwest of Patagonia. The years of excavation resulted in a set of bones (vertebrae and pelvic bones) that once belonged to a giant sauropod that might have been the largest animal to live on our planet.
The fossils have been found in the Candeleros Formation which is a sedimentary rock and was formed 98 million years ago, also known as the Upper Cretaceous epoch.
There was a gap of 3 years between the discovery of the fossils and the start of their excavation in 2015, but so far, the team working on the site has found 24 vertebrae, all belonging to the sauropod’s tail.
The excavations are still ongoing and paleontologists all over the world are eagerly waiting for the rest of the story to unveil.

In the Patagonia region of Argentina, paleontologists have discovered vertebrae from what may be the largest animal to ever walk the earth.

Stuck in sediment dating to the Upper Cretaceous period about 98 million years ago, the fossil appears to be a titanosaur—a type of sauropod dinosaur.

As researchers excavate more of the skeleton, science will learn more about this colossal animal.
