摘要：小型新角龙类恐龙安氏原角龙（蒙古，晚白垩世）的一个显著标本揭示了该属的第一个巢穴，其中有15只幼龙。这些个体相对较大的体型及其发育的高级阶段表明，原角龙幼龙至少在出生后的早期阶段可能留在巢穴中生长。这个巢穴进一步暗示，亲代抚育和群居性在角龙类的系统发育上是基本行为。最后，它再次证实了原角龙生活（并死亡）在中亚克拉通的风沙丘地带这一结论。
Abstract A remarkable specimen of the small neoceratopsian dinosaur Protoceratops andrewsi (Late Cretaceous, Mongolia) reveals the first nest of this genus, complete with fifteen juveniles. The relatively large size of the individuals and their advanced state of development suggests the possibility that Protoceratops juveniles remained and grew in their nests during at least the early stages of postnatal development. The nest further implies that parental care and sociality are phylogenetically basal behaviors in Ceratopsia. Finally, it reaffirms the conclusion that Protoceratops lived (and died) in the sandy aeolian dune fields of the central Asian craton.
