Types of dinosaur eggs

Monday, September 5, 2011

It is very difficult to link dinosaur eggs to the dinosaurs that laid them. Rarely we find an embryo inside an egg. So most of the time we can only classify dinosaur eggs based on their characteristics. Here we give the classification for the Chinese dinosaur eggs.

At this moment, there are four families of eggs found:

This type of eggs is more rare and can be found in central China. They belong to the genus Faveoloolithus sp. They have the thickest shell compared to the other types of eggs. Also are they a little bit bigger than the Dendroolithus, they are flatter and have a rougher ad more undulating shell texture. According to Chinese publications, these eggs are mostl commonly found in the earliest of the late Cretaceous deposits. These eggs are supposed to belong to a group of dinosaurs called sauropods.


These round eggs are the most common found in China. Until now, no embryos have been found in these eggs, so we can't identify the species of dinosaur. We say they belong to the genus dendroolithus sp. These eggs seem to belong to the group of Ornithopoda. Most of the time, scientists assume that they belong to Hadrosaur.

These eggs are generally smaller in size. Their diameters range from 3 to 5 inches. The shell of the egg is often thin. They are most commonly found in the middle of the late Cretaceous Period. They belong to the genus Spheroolithus sp. Recently embryos have been found in one tye of eggs that have this shell morphotype, prove that these egg belong to Segnosaur. The eggs that used to be called Oolithus, are unique because of their preservation. The content of the egg is replaced by carcite, which creates ideal conditions for the preservation of embryonic bones. Go to our webshop to find dinosaur eggs of this kind.


These eggs are approximately 17 inch long and are most commonly found in the late Cretaceous. But also much smaller examples have been found. These dinosaur eggs are elongated. Many fossilised nests show that these eggs were laid in radial nests, somethimes even in more laers. Also the famous Oviraptor eggs belong to this type.
