Once again the fossilized eggs of a dinosaur, Sankofa pyrenaica are being touted as evidence of the evolution of dinosaurs to birds.  While I wrote about this several months ago – Dinosaurs, Birds and Easter Eggs – I wanted to take this opportunity to once again counter the evolutionary argument based on common appearance.

The fossil eggs were discovered in the northeast region of Spain, near the town of Lleida (Lerida).  The area is well known for sauropod dinosaur eggs and is classified as upper Cretaceous, about 70-80 million years in evolutionary time.   But unlike most of the other dinosaur eggs found in the region, the eggs of Sankofa pyrenaica are shaped more like a chicken egg than a typical dinosaur egg.

Based on the ovoid shape of the eggs, evolutionists claim that this is further proof that dinosaurs evolved into birds.  However, the logic of that argument is quite flawed when one looks at the bigger picture.

For one thing, they place the Sankofa pyrenaica eggs at 70-80 million years ago and a number of fossilized birds have been evolutionarily dated to as far back as 150 million years ago.  If this is the first dinosaur to have bird shaped eggs and it lived 70-80 million AFTER birds had already evolved, then I see a problem in their lineage correlation.  Besides, where are all of the other bird shaped eggs that should have been found prior to birds evolving 150 million years ago?

Secondly, the shape of the egg means absolutely nothing in two ways.

The first of these would be that some birds lay eggs that hardly have any pointed end, such as the Emu.  Many Emu eggs are more oval like dinosaurs and reptile eggs, so does that mean that they are evolving back into some kind of dinosaur or reptile?  Hardly and no one would even consider such a suggestion with any sense of seriousness.

Second is the reason for bird eggs to have a pointed end.  As the egg passes through the oviduct, the muscles in the walls squeeze the egg from behind to force it out.  Bird eggs are still somewhat pliable at this stage but harden very rapidly as it passes out of the bird.  The squeezing from behind causes the back end of the end to taper which is maintained as the eggs hardens.

Reptile eggs do not harden, but have a pliable leathery shell.  As in birds, they are squeezed from behind by the muscles surrounding the oviduct.  But unlike bird eggs that harden extremely fast, reptile eggs do not harden at all and thus readily return to their more elliptical shape.  Since dinosaurs are reptiles, their eggs also appear to have had thick leathery shells and would have responded to the same shaping processes as we observe in reptiles today.

So what caused the shape of the Sankofa pyrenaica eggs to be more ovoid like a chicken’s?  We haven’t a clue, but to claim it is proof of ancestry is ludicrous and a very fallacious argument.  It makes as much sense as saying that an octopus evolved into a human because the eye is so similar.

The sad part is that evolutionists are so entrenched by their blind faith in evolution that they don’t think things through logically nor do they see the big picture.  They are trying to see the light by looking down a darkened tunnel with no outlet, when all they have to do is take a good look at the infinitely complex and orderly world around them to realize that only an omniscient and omnipotent Creator could have been responsible for all of nature.
