Products description
Original Dinosaur Egg (Dendroolithus sp. / Hadrosaur)
For sale is a fascinating, scientifically interesting original fossil from a long past era: A real, fossilized dinosaur egg with an excellently preserved shell structure.
This magnificent piece shows the "crush structure" (mosaic pattern) typical for real fossils. Under the enormous pressure of the sediment, the eggshell broke slightly into countless small plates during the fossilization process lasting millions of years, but remained perfectly preserved in its original, three-dimensional shape on the fossilized mud core.
Information on species and origin:
Dinosaur eggs of this quality and size are developing into rarities on the legal, international fossil market. For many years, a strict law for the protection of national natural heritage has been in force in China, which strictly prohibits the export of vertebrate fossils and dinosaur eggs. This offered piece is a historical collector's object that was legally exported a long time ago and has already been in old collections for many years. Since no more legal supply comes from the discovery regions, the supply stagnates worldwide, while the demand among demanding collectors continuously rises. Such pristine, honest pieces are hardly to be found anymore.

Product details, condition and value retention:
- Dimensions: Approx. 13 x 12 x 8 cm (A stately, heavy and hand-filling collector's piece).
- Matrix / Rock: The egg is embedded in the world-famous, iron oxide-rich brick-red matrix (Chinese "Red Beds"), which contrasts perfectly in color with the gray-brown eggshell.
- Value-determining shell preservation: The market value of such a fossil is significantly defined by the degree of preservation of the eggshell. This specimen impresses with an exceptionally comprehensive shell substance (estimated 75-80 percent coverage) that almost completely encloses the core. The shell thickness is an authentic 1.5 to 2 mm.
- Condition: Honest, natural original condition. A few missing shell parts are natural and open the view to the inner stone core, they prove the untouched authenticity. No artificial manipulations, no modern additions or glued-on shell fragments!
