context_page_description: Dyoplosaurus is an extinct genus of ankylosaurid dinosaurs within the subfamily Ankylosaurinae. It is known from the lower levels of the Late Cretaceous Dinosaur Park Formation of Alberta, Canada. It contains a single species, Dyoplosaurus acutosquameus.
context_section_description: The type specimen of Dyoplosaurus was about 4–4.5 m (13–15 ft) long and about 5.8 feet (1.7 m) wide, with a skull measuring 14 inches (35 centimeters) across. Like most other ankylosaurids, it was quadrupedal, ground-dwelling and herbivorous, with an armored body and a bony club on the end of its tail. The club was composed of several armor plates fused together.  The tail club possessed by Dyoplosaurus is relatively small and narrow, when compared to that of other ankylosaurids.
