Rare and fascinating, fossilized dinosaur eggs are highly prized by collectors and paleontologists because they tell an important phase of dinosaur life. Although the number of dinosaur eggs laid was immense, the discovery of fossilized eggs is extremely rare, as many of them were predated or destroyed.
The first dinosaur eggs were unearthed in 1859 by Jean-Jacques Pouech, a Catholic priest and amateur naturalist, but his limited knowledge of natural history led him to mistake them for rather large bird eggs. The first dinosaur eggs recognized as such were found in 1923, in Mongolia, during Roy Chapman Andrews' legendary expedition. In 1977 a site later called "Egg Mountain" was discovered in the Two Medicine Formation, Montana. The fossil site was discovered by Marion Brandvold, owner of the Trex Agate Shop in Bynum, Montana. She found juvenile dinosaur remains at the site and in 1978 showed her findings to paleontologist Jack Horner, who found as many as 14 dinosaur nests. The site provided the first conclusive evidence that dinosaurs fed and cared for their young and, in addition, the first evidence that dinosaurs had complex behaviors.
