Lot 670
Pair of Therizinosaurus Eggs, One With Possible Embryonic Bones. Therizinosaurs were the most bizarre and unusual dinosaurs. They appear to have been a plant-eating theropod related to the raptors. Therizinosaurs walked bipodally with the body, long neck, and small head of a plant-eating dinosaur, but with up to two-feet claws on their hands (artist's conception enclosed). What they used the large claws for is unknown.
Whatever they were, some dinosaur embryos have been found in some of these 3½-4 inch diameter eggs. This lot contains a 4 inch unhatched egg with over 85% of its original shell still in its red limestone matrix, as well as a 3½ inch unhatched crushed egg that has been calcified. The importance of such calcification is that embryonic bones have been found in 5-10% of calcified eggs. The only way to know for sure is to slowly etch the egg to expose any fragile bones present. Both eggs are 65-70 million years old, from the Xixia Basin, Henan Province of China, and are highly displayable, as well as important for study. Total weight is 3 pounds.
Estimated Value $650 - 1,050.
