These 5 Dinosaur Nests Are Among the Biggest Ever Found

Some dinosaurs are positively massive. But like most reptiles, these giants don’t start their lives at those titanic sizes — even relatively speaking.

Many species, though perhaps not all, likely came from eggs laid outside their mothers' bodies. But paleontologists have yet to discover the eggs of many dinosaurs. Perhaps unsurprisingly, these highly delicate embryo cradles probably didn’t last more than a few months, let alone the huge epochs of geological time scales.

But regardless, some nests have survived in fossilized form, and in great numbers. Here are some of the largest nests ever discovered.
