Nesting Sites

The annual nesting of the Maiasaurs must have been an incredible spectacle. A herd of 2,700 would have gathered in the dry alluvial plains of the Cretaceous, building 1,350 nests over an area estimated at two-thirds for a kilometer in diameter. With the arrival of the rains, the nearby brush land became rich in vegetation. The nests were soon alive with the sounds of hatchlings. Parents would begin making the regular trips to gather vegetation for the young.
