A whale of a tale! In a video, get the inside view from Museum curators about our newest exhibition, Whales: Giants of the Deep, which opens Saturday, March 23, 2013.

A video series on amnh.tv delves into the topic of dinosaurs, which arose some 230 million years ago and thrived until large dinosaurs became extinct about 65 million years ago. How did dinosaurs reproduce? A video explains.

What did extinct dinosaurs eat—and how do we know it? Find out more from Michael J. Novacek, the Museum's provost of science, and Mark A. Norell, chair of the Division of Paleontology, in a video. 

Visit the David H. Koch Dinosaur Wing on the Museum's fourth floor, and you'll find a bevy of fossil dinosaurs, in two separate halls. One is the Hall of Ornithischian Dinosaurs (Or-nuh-THISH-ee-an); the other is the Hall of Saurischian Dinosaurs (Sawr-ISH-ee-an). A video explains the difference.
