Caption 3 The Great Interior Seaway The new Cretaceous Hall will feature a recreation of the remarkably diverse life that existed in a vast seaway that extended across western North America from today's Arctic Ocean to the Gulf of Mexico. Monstrous marine reptiles and giant sea turtles will share this part of hall with other incredible animals, such as strangely coiled ammonites and massive coral-building clams.

Caption 9 Cretaceous Hall Model (115 - 65 million years ago) The early Cretaceous witnessed a very important event - the origin of flowering plants. Mammals were still small, but becoming more diverse. Feathered non-flying dinosaurs trudged the earth, while their relatives, the birds, soared in the skies. Pterosaurs developed into incredible flying machines with some having wingspans of nearly forty feet. In the late Cretaceous, North America was divided into two parts by an immense shallow seaway that extended from the Arctic to what is today the Gulf of Mexico. These seas were teeming with life, including immense marine lizards - the mosasaurs - and many kinds of bony fishes.

THE PRESENT HALL Today, Carnegie Museum of Natural History is home to one of the world's best collections of dinosaur fossils. Dinosaur Hall features more than a dozen skeletons in a space originally built for one.

THE HISTORY OF DINOSAUR HALL In 1899, a year after they were dispatched to Wyoming to find dinosaurs, the Carnegie team discovered a new species, Diplodocus carnegii, which was named after its benefactor. Carnegie built Dinosaur Hall as a home for Dippy, and then shared the find with the world by creating casts for museums around the world.
