Oh my God. Do you know what this is? This is a dinosaur egg. The dinosaurs are breeding.

Dr. Alan Grant, Jurassic Park movie (1993)

We are again approaching Easter time and, as tradition, I would like to celebrate with an article dedicated to the most perfect thing in nature: the egg. I came across interesting books about the discovery of dinosaur eggs last year. Dinosaurs are the ancestors of birds and modern reptiles, so we will take a little detour from the traditional Easter egg, and with the spirit of equal opportunity justice, we will look at the shape of these.
