Lot 0061H
Ancient World, Upper Cretaceous, ca. 100 to 66 million years ago. A round, fossilized dinosaur egg from a red sandstone formation. The shell structures are nicely preserved. The round shape tells us that this egg belonged to a herbivorous dinosaur, probably a hadrosaur. Although it looks huge compared to many modern eggs, it is mid-sized for a dinosaur - the largest known dinosaur eggs are twice this size (and yielded animals who could grow to be nearly a hundred tons!). Size: 5.3" L x 6" W x 5.5" H (13.5 cm x 15.2 cm x 14 cm)

Hadrosaurs, also known as duck bill dinosaurs, are thought to have been good parents who watched carefully over their nests, based on nest sites found in western Montana. Newly hatched hadrosaurs were small - around a foot long - and weighed about 1.5 lbs. Their parents would have brought them fruits and leaves as they rapidly grew to be thirty foot long, three ton adults.
