An important contribution made by the study of dinosaur eggs from
the Upper Cretaceous Period :
Dinosaur egg shells are the most frequently discovered fossils from the
"brief" period that preceded the dinosaurs' extinction. In
addition, eggs have been found in all geological formations corresponding
to the period, from the oldest to the most recent. By following the
evolution in their shapes from the beginning to the end of the period,
scientists are acquiring a good idea of the changes in the diversity of
the eggs and thus the diversity of the dinosaurs.
