2. The iconic Blue Whale model

One of the museum’s most popular attractions is the life-size, 94-foot-long model of a blue whale suspended from the ceiling of the Milstein Hall of Ocean Life. The whale is so huge, it takes three entire days to clean it.

3. The Titanosaur barely fits

The museum’s Titanosaur, one of the largest dinosaurs ever discovered, is so massive (122 feet long) that it had to be posed with its head and neck sticking out of the exhibit room into the hallway.

4. There’s a hidden time capsule

The museum was tasked with safekeeping The Times Capsule, commissioned by The New York Times Magazine and designed by architect Santiago Calatrava. The five-foot stainless-steel vessel, set to be opened in the year 3000, has inside its crevices Rev. Dr. Martin Luther King Jr.’s “I Have a Dream” speech, a Purple Heart from the Vietnam War, a cellphone, and more.

5. The original T-Rex had the wrong pose

Did you know the T-rex didn’t actually stand upright? When the museum first mounted its Tyrannosaurus rex skeleton in 1915, it was incorrectly posed standing upright like a kangaroo. It wasn’t corrected until 1993 to show a more scientifically accurate, horizontal stance.
