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.
