Iguanodontoidea

† Iguanodontoidea — the superfamily of iguanodontian ornithopods including Iguanodon, hadrosaurs, and relatives. Dominant Cretaceous herbivores; large herbivores with sophisticated dental batteries and flexible forelimbs. Originated in the Late Jurassic; reached peak diversity and size in the Late.

Diet & Feeding

Herbivore

Iguanodontoidea 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

Iguanodontoidea 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.
