Dyoplosaurus was found in the lower levels of the Dinosaur Park Formation area of Alberta, Canada in 1924. Its name means “double-armored lizard.” Paleontologists believe this dinosaur lived in North America during the Late Cretaceous Period. Only one Dyoplosaurus specimen has been discovered.
Dyoplosaurus was approximately fifteen feet long and six feet wide. Its skull was fourteen inches across. This dinosaur walked on four legs and only ate plants. The Dyoplosaurus’ body was protected with armor, and it had a hard club at the end of its tail. Spikes ran down the Dyoplosaurus’ back with two more massive spikes located behind its neck.
