This is an artist's rendering of the massive dinosaur Dreadnoughtus schrani.In life, Dreadnoughtus was an herbivore that likely spent much of its life eating massive quantities of plants to maintain its enormous body size.

The skeleton of the dinosaur at the site where it was discovered and unearthed by a group of researchers in southern Patagonia, Argentina.

Kenneth Lacovara, an associate professor at Drexel University, who led the excavation and analysis of the skeleton, surrounded by fossilized bones of Dreadnoughtus schrani at the excavation site in Argentina.

A pair of bones called a 'chevron' which occur along the bottom of the dinosaur's tail. In Dreadnoughtus, the lower portions of the chevron bones have an unusually large surface for muscle attachment, indicating that this dinosaur’s tail was extremely muscular and powerful.

Bones of Dreadnoughtus schrani in Lacovara’s fossil lab at Drexel University. Scapula (shoulder blade) (standing against divider); Cervical (neck) vertebra (on pallet), surrounded by preserved neck tendons; Sternal (chest) plates (front of table); Dorsal (mid-back) vertebrae (rear of table).

Lacovara’s team prepared 3D laser scans of most of the fossil bones from Dreadnoughtus schrani, making them available to other researchers for future study.

This composite image shows the tail bones of the Dreadnoughtus schrani specimen. This individual’s tail would have been 30 feet in length.
