Details:

Rare Oviraptor partial crescent egg nest discovery a scientifically important find in Xixia Basin Kaoguo Formation, in the Henan Province of China. From the Mesozoic era, in the fossil layer of the Maastrichtian stage, the late Cretaceous period around 72 to 66 million years ago. Science has determined The oviraptor dinosaurs were paternally protective of their nests, adult oviraptor dinosaur skeletons have even been found lying over their eggs, one can only guess at why this is so possibly as some cataclysmic event befell the nesting grounds, the parent oviraptor could have been shielding the nest from harm or possibly a predator other theories put forward include the adult died while incubating their eggs. Discoveries made in the last few decades have helped to substantiate the theory of bird-like behaviour among oviraptor dinosaurs and the sedentariness of the parents has given more clues to the habits of oviraptors, it is now thought they did brood over their eggs and possibly stayed with the hatchlings for a period of time. Oviraptor was about the size of an Ostrich or Emu. When first discovered it was described as a bird-like dinosaur. The oviraptors strong beak-like jaws capable of cracking down on its prey. Again recent discoveries learn towards oviraptors the diet consisted of mollusc and crustacea and perhaps supplemented by slower prey it could catch, even small lizards.

Details

Oviraptor nest of 12 eggs in a partial clutch on the original matrix, or fossil sediments now hardened to limestone, over the last seventy million years. There where more eggs from this nest which would have completed a circular lay pattern, the ovoid eggs laid at an angle from the centre. The eggs were laid concentrically in pairs, and are inclined to the ground at low angles, sloping away from the nest centre, this is familiar to this genus of oviraptor dinosaur and several egg nest discoveries. Overall the eggs exhibit pale tones, with traces of light maroon, yellows and greys colour. All are of very good preservation and condition each egg having a fairly unchanged form, i.e. the eggs are still inflated in shape, not badly squashed, so display a three-dimensional shape true to the time they were laid down by the raptor dinosaur in the Cretaceous period. Some eggshell has been eroded away which is entirely expected of dinosaur eggs of this age.

 

The name Oviraptor means "egg-seizer" in Latin because the first fossil remains of the genus were found atop a nest of eggs. As further dinosaur skeletons and bones were unearthed it became apparent that these Oviraptors were actually brooding over their own eggs. As well as this familiarly bird-like nesting behaviour, some species are believed to have boasted a full-body covering of feathers.
