Fukuisaurus tetoriensis

† Fukuisaurus tetoriensis — an Early Cretaceous iguanodontian ornithopod from Japan's Kitadani Formation. Medium herbivore (~4–5 m long); one of Japan's first named dinosaurs. Quadrupedal browser. Named for Fukui Prefecture, which has yielded Japan's richest Early Cretaceous dinosaur assemblage.

Diet & Feeding

Herbivore

Fukuisaurus tetoriensis 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

Fukuisaurus tetoriensis 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.
