There’s no way to count the number of times that people get upset because his actual scientific name is no longer Brontosaurus.

He’s one of the most famous dinosaur celebrities in the world and you may know him as Brontosaurus from your Flintstone days, but his real name is the Apatosaurus.

So just think about it….It’s the perfect day for you to learn to say his “Irish” name — A-PAT-o’saurus. Isn’t that better? Go over to wish him well this weekend.

He’s the largest dinosaur on display in New York. He came here all the way from Wyoming, and he’s been standing here since 1905, when J.P. Morgan and the AMNH crew unveiled him. It was the first time that a really big dinosaur was ever mounted in 3D anywhere in the world.

To the left is the “architect’s model” that the 1905 crew used to figure out how to weld together enough steel to keep the tons of rock up in the air. A-PAT-o’saurus, Happy Irish Day!
