卖家的描述
Scientific name: Oviraptor cf philoceratops, Osborn 1924. Fossilized partial Egg. form Macroolithus yaotunensis (Elongatoolithidae). Preserved in its natural matrix.
Location: Eastern Asia
Age: Upper Cretaceous, Campanian stage, (~75 Million Years)
Size: 7,5 x 6,5 x 3cm - Matrix: 14 x 12 x 3,5cm
REF.: #J712
DESCRIPTION:
Oviraptor eggs from the Late Cretaceous are elongated, ridge-textured, and were originally mistaken for Protoceratops prey, but subsequent finds of embryos (e.g., IGM 100/971) confirmed they belong to Oviraptor.
These eggs, often arranged in pairs within circular, brooding nests, demonstrate that these theropods displayed bird-like nesting behavior.
Key Details on Djadokhta Oviraptor Eggs:
Initial Misconception: Discovered in 1923 by Roy Chapman Andrews, they were thought to be stolen eggs from Protoceratops, leading to the name "egg thief".
Brooding Evidence: Fossil finds, such as the one described in 1993, showed that the adult was not stealing the eggs, but instead brooding, or sitting on, its own nest.
Egg Characteristics: The eggs are of the form Macroolithus yaotunensis (Elongatoolithidae). They are characterized by their elongated shape (approx. 163–198 mm long) and a surface with ridges aligned to the long axis.
Embryo Discoveries: Significant specimens include IGM 100/971 (first known theropod embryo) and others from sites like Ukhaa Tolgod, which solidified the link between the eggs and the parent.
Nesting Structure: Eggs were arranged in pairs, forming a circular, open, or partially covered nest, often with 15 or more eggs.
Pigmentation: Research on oviraptorid samples suggests these eggs possessed pigments, likely giving them a blue-green color, similar to some modern birds.
These discoveries were crucial in bridging the understanding of the relationship between dinosaurs and modern birds.
Observations abour our specimen: Authentic Oviraptor egg, preserved at approximately 30-40% of its original structure.
The specimen is completely unrestored, featuring only a small, carefully reattached fractures.
Despite its partial preservation, this remains an exceptional fossil specimen, highly valued for its authenticity, natural condition, and rarity. Its also preserved in its natural matrix.
All of our fossils come with a Certificate of Authenticity. Every week, the issued Certificates of Authenticity are updated in our database verification system on our website. If you find that your certificate has not yet been updated, please contact us and we will update it immediately. Display box NOT included.
