Problematic issues i dinosaur eggs
Problematic Issues I:Dinosaur Eggs

  • Are the dinosaur egg sites really nests?

  • Are there multiple levels of dinosaur nests and eggs?

  • Are these sites pre-Flood, Flood or post-Flood deposits?

Part v summary
Part V: Summary

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.
