Most dinosaur eggs are found in sandy shores of old waterways. They are situated in clusters of 6-8 laid during Cretaceous period. Anatomically, dinosaurs have two oviducts or ovaries linked to a tube where tough shelling occurs.
There are two main types of dinosaur eggs shapes/ construction: spheroidal and elongated. They might be subdivided into three types:
- Spherulithic egg shells have spherical patterns
- Prismatic egg shells is a variety of spherical and prism habits
- Ornithoid egg shells have biocrystalline upper to be able to middle patterns
Egg classifications using the type of dinosaur which often laid them are:
They appear in circular to subspherical shape with very long thin crystalline component. They’ve spherulithic shells in construction. Most of this specie has been discovered in Argentina. To enhance your knowledge about dinosaur eggs, hop on to http://www.geoevo.com/.
They include Troodon, Ovirator, Therizinosaurs varieties. Troodon appear to possess elongated shape with ornithoid cover type. Ovirator offers elongated and elliptical patterns. They have unique nodes and ridges inside the surface. Therizinosaurs have 2 types the Manning egg and Louie egg. There’re spherical and elongated patterns. Most of this specie was present in Montana.
There’re rounded with slight elongated appearance. They have longitudinal ridges inside the surface. Egg shells usually are spherulithic in structure. Most ofthi species are also found in Montana.
Regarding the behavior or manner of egg laying, here are many of the theories made by egg discoverers:
- Dinosaurs lay eggs one pair at any given time
- Some of usually are laid in nests while other people are in soil as well as debris
- Some dinosaurs hot eggs by their abdomens people use their throat as well as thorax.
- They can lay possibly 21-33 eggs in 1 nest.
- Eggs usually are carefully hatched. Shell openings are found on top layer this means hatching occurred upward.
Dinosaurs eggs were covered by predators: smaller dinosaurs
