Brontomerus mcintoshi

Brontomerus mcintoshi 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.

Brontomerus mcintoshi lived during the Cretaceous Early period of the Mesozoic Era, approximately 145.0 to 100.5 million years ago.
