Psittacosaurus mongoliensis, green and brown, Prehistoric Kingdom

Did you know that some primitive ceratopsians were known to use gastroliths to aide in digestion? These rounded pebbles, which were seemingly used for grinding down plant material in their guts, have been found in the body cavity of both #Psittacosaurus and #Yinlong.
