News posts

In the video below, Curator Mark Norell, who is chair of the Museum’s Division of Paleontology and studies important feathered dinosaurs from Liaoning, China, shares his thoughts on the significance of two new studies about fossilized feathers reported in the current issue of Science magazine.

NPR Traces History of Barnum Brown’s First T. Rex Skeleton

News posts

It’s a story more than a century in the making. Barnum Brown’s extraordinary fossil-hunting career—which took him from a frontier farm to the world’s top fossil sites and to the halls of the American Museum of Natural History—included the discovery of the first complete skeleton of the Tyrannosaurus rex.

The priceless fossil—the one used to describe the carnivorous species now synonymous with “dinosaur”—was displayed in the Museum for more than 30 years beginning in 1906. Then the story took a twist, which is traced in a recent NPR piece “Bone To Pick: First T. Rex Skeleton, Complete At Last.”

Titanosaur Nest from The World’s Largest Dinosaurs

News posts

They are some of the rarest of rare artifacts: fossil dinosaur eggs with the embryo still inside. And they are prized for what they can tell paleontologists about the adults that laid them.

The exhibition The World’s Largest Dinosaurs features a scale model of a 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 titanosaurs are thought to have laid the thousands of eggs — 15 to 40 at a time — in shallow nests dug out with their huge feet in dry mud and sand over miles of ground at Auca Mahuevo.
