Dyoplosaurus acutosquameus

† Dyoplosaurus acutosquameus is an ankylosaur dinosaur from the Late Cretaceous (Campanian) Dinosaur Park Formation of Alberta, Canada. Estimated at around 6 m in length, it was a low-slung quadruped herbivore covered in sharply-keeled osteoderms (reflected in its species name, acutosquameus, 'sharp-scaled'). It wielded a bony tail club for defence against tyrannosaurids. For decades confused with Euoplocephalus, it was re-established as a distinct genus in 2009.

Diet & Feeding

Herbivore

Dyoplosaurus acutosquameus was a plant-eating dinosaur. Herbivores typically fed on ferns, cycads, conifers, and other vegetation available during their era. Many herbivorous dinosaurs developed specialized teeth and digestive systems for processing tough plant material.

Time Period

Cretaceous Late Mesozoic Era

Dyoplosaurus acutosquameus lived during the Cretaceous Late period of the Mesozoic Era, approximately 100.5 to 66.0 million years ago.

The final age of dinosaurs, featuring iconic species like Tyrannosaurus rex, Triceratops, and Velociraptor. Dinosaurs reached their peak diversity before the catastrophic asteroid impact at the Chicxulub crater ended the Mesozoic Era.
