Description: Name: Dendroolithus Hadrosaur Egg Age: Cretaceous Formation: Kaoguo Formation Location: Xixia Basin, Henan Province, China Size: Egg is about 7.3 inches long!This is a GUARANTEED REAL fossilized dinosaur egg from the dinosaur, Oviraptor, or "egg robber". Most raptors laid their eggs in nests of a dozen or more eggs. Oviraptor mothers have been found fossilized guarding their nests, showing a “nurturing” nature in these dinosaurs. Usually, hatching and scavenging damaged the nests, obliterating any trace of the eggs that remained. Occasionally, some eggs survived predators and the elements, and eventually became fossils. Because of their delicate nature, intact eggs are very rare in the fossil record. Dinosaur eggs that retain their original shape and eggshell are some of the most collectible fossils in the world.Another point of interest relating to Raptor eggs is the overall comparison of eggshell thickness of these eggs. The Raptor eggs found in deepest deposits (older) have very thick eggshell. As you examine eggs higher in the formation (younger), you see a gradual thinning of the eggshell over time. Gradual changes in vegetation (determined from pollen samples), changes in climate from a humid subtropic to an arid temperate region, and less oxygen in the air (determined from examining air trapped in amber) could have weakened the dinosaurs ability to produce healthy eggs, thus leading to their inevitable extinction. Environmental stresses in modern birds (the brown pelican, for example) have been shown to reduce the thickness of eggshells and the results on the species are similar. This amazing Raptor egg was cleaned under a microscope in the EXTINCTIONS Prep Lab here in the USA. The impressive egg has been extracted from the surrounding rock, fully free of matrix, and can be viewed from all angles. The giant egg (over SEVEN inches long!) is wonderfully inflated and 3-D and has excellent oval "egg" shape and form. ALMOST ALL of the black, reticulated eggshell is still intact and is easily seen (see photos). And one of the coolest features of this egg is that it is a hatched egg - you can easily see the "hatching scar" on the egg (the red parts) where the baby crawled/hatched out of the egg - WOW! This is an extremely detailed and displayable Oviraptor dinosaur egg with hatching scar - a REAL specimen for your collection, to display in your home or office, or for a unique gift for the person who has everything - what a conversation piece!A Certificate of Authenticity from EXTINCTIONS.com is included with this specimen.
