Scolosaurus is an extinct genus of ankylosaurid dinosaurs that was a member of the family Ankylosauridae and the subfamily Ankylosaurinae. The fossils of this Campanian Late Cretaceous extinct genus creature have been discovered in the Dinosaur Park Formation and Oldman Formation in Alberta, Canada.

This genus comprises only two species: Scolosaurus cutleri, and Scolosaurus thronus, which are the oldest known ankylosaurid dinosaurs of North America. They are assumed to have existed in the Campanian stage of the Late Cretaceous in the Dinosaur Park Formation.

The name of this genus was given in 1928 by Franz Nopsca and means pointed spike lizard. The dinosaurs of this genus belong to the order Ornithischia. The ankylosaurid dinosaurs are estimated to have attained a length between 19.6-21.3 ft (6-6.5‭ ‬m) and weighed 4,000 lb (1800 kg). They are thought to have been medium in size, possessing a clubbed tail and thick skin, along with bony armor plates. Their diet comprised plant-based material.

A ‬study by Currie and Arbour in 2013 had suggested‭ ‬that the genus Oohktokia is Scolosaurus's junior synonym.

Scolosaurus Fun Facts

What did a Scolosaurus look like?

The Scolosaurus possessed thick skin with osteoderms and a clubbed tail that provided protection.

The appearance of the Scolosaurus is estimated through an almost complete skeleton specimen that was excavated from Alberta, Canada, but did not include a skull. It is believed to have been an ankylosaur of medium size that had thick skin. This thick skin had osteoderms (bony armor plates) that provided protection to this dinosaur from predators. Its clubbed tail also provided defense against predators like Tyrannosaurs.

The species Euoplocephalus tutus and Scolosaurus cutleri were initially synonymized. However, Scolosaurus possessed different cervical armor and was thus distinguished from Euoplocephalus!

A ‬study by Currie and Arbour in 2013 had suggested‭ ‬that the genus Oohktokia is Scolosaurus's junior synonym.

The 'cutleri' part of Scolosaurus cutleri, was kept in the honor of the discoverer of this species, W. E. Cutler. The specimen fell on top of Cutler, leaving him severely injured.

The specimen of this genus can be seen in Bozeman, Montana at the Museum of the Rockies.

Barnum Brown gave the subfamily Ankylosaurinae and the family Ankylosauridae their respective names.
