Possible Overbank Deposition
Some Nests Promising
Eggs & fragments indicate transport
Sediments indicate no nest here
Two layers found here
Six eggs encased in plaster
Multiple levels of eggs
Fragment orientations & distributions
Sediments indicate transported eggs
Crushed eggs with internal shell fragments

Sediments suggest transported eggs
In the literature, authors cite single and multiple eggs as “nests.” Regions estimated to have hundreds of eggs are considered nesting grounds. Little work has assessed the nature of the sediments in which the eggs were deposited. Consequently, there is little, if any, evidence for dinosaur nesting behavior.
