Sphaerotholus triregnum

Sphaerotholus triregnum 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.

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