Dinosaur Skin

Have any dinosaur embryo skin impressions been found?

Yes, for the first time ever, the skin impressions of dinosaur embryos have been discovered at a large nesting site in the Patagonian badlands of Argentina, South America. The eggs at the site—nicknamed “Auca Mahuevo” (“huevo” meaning egg) by paleontologists because of the large number of dinosaur eggs found there—are approximately 70 to 90 million years old, placing them in the Late Cretaceous period. Some of the eggs contained embryos, with patches of fossilized baby dinosaur skin. The skin had a scaly surface, similar to that of modern lizards. One skin impression had a distinct stripe of larger scales near its center, a section that probably ran down the dinosaur’s back.
