- Lot Description
East Asia, modern day China, later Cretaceous Period, ca. 100 to 66 million years ago. A trio of theropod eggs preserved atop their original matrix, with a cluster of two on top of a third that would have originally also been part of a pair. The interiors have fossilized to a hard, dark red sandstone, while the eggshells, also fossilized, are black, with the texture of the shell nicely preserved in many areas. The eggs appearing in "pairs" tell us something important about female dinosaurs. Modern birds, the descendants of dinosaurs, have evolved to only have one ovary - believed to assist them in being light enough to fly - but female dinosaurs laid their eggs in pairs, indicating that they still had both ovaries. The layered tiers of eggs are also fascinating, giving us an idea of how many eggs these animals could lay in a breeding season. Size: 4.45" W x 6.25" H (11.3 cm x 15.9 cm)
It is almost impossible to discern what species eggs are from, but it is possible to classify the general type - elongated ovoid forms are from theropods. These are the bipedal carnivorous dinosaurs, including T. Rex and the various forms of including Velociraptor and Oviraptor. These eggs would have been laid in an open nest formation, much like those of most birds today - this was actually rare among dinosaurs, who generally buried their eggs in dirt and vegetation, like crocodiles. Scientists believe that some species of smaller theropods - the maniraptorans - evolved to have open nests and brooding behavior, meaning that they carefully watched over their nests before and after their young hatched. This is thought to be an important step towards the evolution of birds putting their nests into trees.
