Brighstoneus simmondsi

† Brighstoneus simmondsi was an Early Cretaceous styracosternan iguanodontian from the Wessex Formation of the Isle of Wight, England. This large herbivore, approximately 8 m long, is distinguished from Mantellisaurus and Iguanodon by features of the skull, teeth, and vertebrae. Named after the village of Brighstone on the Isle of Wight, it adds to the known diversity of Wealden ornithopods.

Diet & Feeding

Herbivore

Brighstoneus simmondsi 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 Early Mesozoic Era

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

The Cretaceous saw continued dinosaur evolution with the rise of ornithopods and early ceratopsians. Flowering plants first appeared and began to transform terrestrial ecosystems. Spinosaurus and other large theropods lived during this time.
