Titantosaurus are some of the rarest of rare artifacts: fossil dinosaur eggs with the embryo still inside.

The exhibition The World’s Largest Dinosaurs features a scale model of a Titantosaurus nest found at Auca Mahuevo, Argentina, one of the largest known dinosaur nesting sites in the world. While it isn’t always possible to figure out which dinosaur laid a particular egg, in this case, an embryo within an egg found at Auca Mahuevo site allowed scientists to identify these eggs as those of titanosaurs, a group of sauropods that included such species as Ampelosaurus and Saltasaurus.

Herds of female Titanosaurus or Titanosaurus indicus are thought to have laid the thousands of eggs, 15 to 40 at a time in shallow nests in dry mud and sand over miles of ground at Auca Mahuevo.

Titanosaurs are among the biggest sauropods, the group of saurischian dinosaurs featured in this exhibition. Titanosaurus fossils have been found on every continent except Antarctica, and some of the biggest titanosaurs have been discovered in South America. These include the massive Argentinosaurus. In life, an adult Argentinosaurus could weigh up to 90 tons.

The eggshell is very brittle, so the larger the egg, the thicker its shell must be to keep from shattering. However, the shell must also allow oxygen and water to get through to the embryo growing inside, and, above a certain size, the egg wouldn’t be both suitably strong and porous. So although the Titantosaurus or Titanosaurus indicus sauropod young grew big very fast, they started out relatively tiny.

Dinosaur eggs are the organic vessels in which a dinosaur embryo develops. When the first scientifically documented remains of dinosaurs were being described in England during the 1820s. In 1859, the first scientifically documented dinosaur egg fossils were discovered in France by Jean Jacques Poech.
