Psittacosaurus xinjiangensis

Psittacosaurus xinjiangensis 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.

Psittacosaurus xinjiangensis lived during the Cretaceous Early period of the Mesozoic Era, approximately 145,0 to 100,5 million years ago.

O Cretáceo viu a evolução contínua dos dinossauros com a ascensão dos ornitópodes e dos primeiros ceratópsios. As plantas com flores apareceram pela primeira vez e começaram a transformar os ecossistemas terrestres. Spinosaurus e outros grandes terópodes viveram neste período.
