Fossilized dinosaur eggs are amongst the rarest finds at dig sites, say experts. Yet, they do exist, and these research treasures can provide important glimpses into the evolutionary process of dinosaur features.
Stephen Brusatte, a paleontologist at the University of Edinburgh and author of The Rise and Fall of the Dinosaurs, explains that these rare finds have only been made for a limited number of dinosaur species.
“There are many groups of dinosaurs whose fossilized eggs have yet to be found, including famous ones like tyrannosaurs and stegosaurs.”
Some especially valuable eggs hold well-preserved embryos inside them.
