A wide range of dinosaur species, large size, can be found from a large number of dinosaur egg fossils, although the size is not consistent, but the difference is not very big. The fact is that the size of the eggs produced by dinosaurs does not grow proportionally to the size of their bodies. If the proportion of growth, those several storeys tall dinosaur is bound to produce 18-inch TV machine size of eggs. But we have never found such a large egg fossils.
    The world's largest dinosaur egg fossils are as big as basketball, and very rare. Dinosaur eggs than the current bird eggs, but compared to the body of the dinosaur is very small, especially the big dinosaur eggs even more so. Why do big dinosaurs have little eggs? Scientists explain this: if the dinosaurs under the eggs are too large, protein, egg yolk, the pressure on the eggshell is big, eggshell can not withstand, very easy to break. If the eggshell is too thick, the dinosaur baby is very difficult when it comes out of the shell. The baby can not break the eggshell, out, will die in the egg.
    Moreover the egg is too big, the goal is also big, easy to incur the predators, is not easy to survive. And the size of the eggs is too large, the number of eggs produced by dinosaurs will be reduced, which is very detrimental to the dragon's lineage. Because the survival rate of the newborn reptiles is very low, it is speculated that the death rate of the dinosaur cubs is also very high, and dinosaurs, like the existing reptiles, take more eggs and eggs to increase the number of offspring. Just out of the shell of the dinosaurs, although small, but life is long, and long life, so can grow into a big man.
    So to make the simulation dinosaur eggs, we must remember these essentials.
