Siamodon nimngami

† Siamodon nimngami is an Early Cretaceous iguanodontian from the Sao Khua Formation of Thailand, among the best-known ornithopods from Southeast Asia. Its discovery broadens understanding of iguanodontian biogeography across Mesozoic Asia.

Diet & Feeding

Herbivore

Siamodon nimngami 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

Siamodon nimngami 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.
