Reconstruction

What did the landscape look like? From the geology we know the nesting area was a low floodplain.

Research has also revealed that the landscape included sparsely dispersed trees, horsetails and other dinosaurs.

Envisioning dinosaur behavior is more difficult since behavior doesn't usually leave a fossil record. We believe that large groups of adults dug nests in which to deposit their eggs. Although it appears the parents didn't sit on the nests or care for their eggs, it is still unclear what role adults had after the babies hatched.

Most of the time the dinosaur colony nested successfully. But like floodplains today, this site was covered occasionally with overflowing water and silt from a nearby river, preserving the eggs as fossils for millions of years.
