Dinosaur eggs are surprisingly (to the non-biologist) similar in size. Even the very largest dinosaurs laid eggs that were hardly any bigger than the largest eggs found today. These are observations from the fossil record and these observation make sense biologically even though all we see are fossilized eggs. Eggs are limited in the size they attain for several reasons but one of the most important is that the embryos in the eggs must have oxygen to grow.
