Knowra Psittacosaurus Psittacosaurus Psittacosaurus is an extinct genus of small, beaked herbivorous ceratopsian dinosaurs from Early Cretaceous Asia. Its species are known from abundant fossils, including exceptionally preserved juveniles and soft tissues.
Ceratopsia : Ceratopsia is the dinosaur group that includes Psittacosaurus, horned dinosaurs, and their close relatives. Psittacosaurus is an early-diverging ceratopsian, far outside the familiar horned forms.
Psittacosaurus mongoliensis : Psittacosaurus mongoliensis is a species of Psittacosaurus named from fossils found in Mongolia. This species anchors the genus’s history and is represented by many well-studied specimens.
Herbivory : Herbivory is the consumption of plants or plant parts by animals. Its beak and jaws were adapted for cropping and processing plant food.
Early Cretaceous : The Early Cretaceous is the first epoch of the Cretaceous Period, spanning about 145 to 100 million years ago. Psittacosaurus lived during this interval, when Asian dinosaur faunas were diversifying.
Dinosaur integument : Dinosaur integument is the external covering of dinosaurs, including scales, feathers, and other skin structures. Psittacosaurus fossils preserve scales and bristles that broaden evidence for dinosaur coverings.
Dinosauria : Dinosauria is the group of reptiles that includes birds and all extinct dinosaurs. Its skeletal features place Psittacosaurus among ornithischian dinosaurs.
Psittacosaurus lujiatunensis : Psittacosaurus lujiatunensis is a species known from Early Cretaceous deposits in northeastern China. Its specimens include fossils preserved in volcanic ash, central to debates about mass mortality.
Dinosaur growth : Dinosaur growth is the increase in body size and skeletal maturity during an individual’s life. Growth series show how Psittacosaurus changed dramatically from hatchling to adult.
Cretaceous Asia : Cretaceous Asia was a changing landmass of environments and ecosystems that supported diverse dinosaur communities. The genus’s fossils come from several parts of Asia, especially China and Mongolia.
Dinosaur camouflage : Dinosaur camouflage is the use of coloration or patterning that reduces detection by predators or prey. Its reconstructed countershading links fossil color patterns to the lighting of its habitat.
