Iguanodontia

† Iguanodontia — the clade of ornithopod dinosaurs including Iguanodon and all more derived ornithopods. Herbivores ranging from small bipeds to massive quadrupeds. Originated in the Late Jurassic; dominated Cretaceous terrestrial herbivore guilds globally. Includes hadrosaurids, rhabdodontids, an.

Diet & Feeding

Herbivore

Iguanodontia 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

Iguanodontia 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.
