Hadrosaurus Nest Of 7 Eggs


Availability:In stock


Hadrosaurus Nest Of 7 Eggs which were discovered in China and laid by an ornithischian dinosaur 'Hadrosauridae', also known scientifically as 'Dendroolithus' from the Kaoguo Formation in Xixia Basin, Henan Province, China dating back to the Mesozoic era, late Cretaceous, Maastrichtian stage around 70 to 65 million years. These eggs were saved from being used as building material more than two decades ago. We at the fossil store have prepared them and surmounted them for a perfectly attractive and scientific museum type exhibit. A rare and extraordinary occurrence of prehistoric nature, the eggs having been fossilised for all time.

Hadrosaurus nest of 7 Eggs supported on a stainless steel stand, the Hadrosaur egg nest extremely fine and well prepared, that is cleaned from the fossil bedrock that once encased it. Hadrosaurids, translates from the Greek hadros as 'stout or bulky' so bulky lizard. A group of herbivorous dinosaurs, the ornithischian family Hadrosauridae. The hadrosaurs laid eggs in nests and each nest could hold up to a total of 12 eggs or more. It is difficult to find a complete intact Hadrosaur egg nest with complete shell coverage and of fine preservation. Large quantities of dinosaur eggs were discovered in the 1980's to 1990's, these were exported from China by palaeontologists who noted the dinosaur eggs while on expeditions in the Xixia Basin region where they had been historically used to build into structures, such as houses and walls in rural areas.

The eggs have since been commercially purchased from rural areas directly by foreign collectors. In the early hedonistic days of collecting without much jurisdiction eggs exchanged hands for a small price per egg. Ultimately finding the way to market for the price of $1500.00 USD each single egg before the market eventually settled down to an influx of eggs and the price steadied around $500.00 USD per egg and held that value until a total ban on exportation of all fossil eggs from China was pressed, including many other fossils. The original ban had been in place since about the early 1990's, it wasn't until after the late 1990's the law was enforced severely and the flow of fossils reduced and eventually ceased from China. Today the only eggs or nests available on the international markets are those which have been purchased before the ban making them scarce, thus holding them for investment purposes as well as admiration for their rarity has been a steadily increasing proposition. Still in China there are fossil markets and dinosaur eggs are traded in the main cities, along with other extraordinary fossils, the ban on trading in fossils has seemingly only affected the foreign markets, the domestic market continues to trade in dinosaurian fossils.
