Shuangmiaosaurus gilmorei

† Shuangmiaosaurus gilmorei is an Early Cretaceous iguanodontian from Liaoning Province, China. This large ornithopod herbivore inhabited wetland environments of the Yixian or Jiufotang biota, foraging on low-growing vegetation.

Diet & Feeding

Herbivore

Shuangmiaosaurus gilmorei 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

Shuangmiaosaurus gilmorei 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.
