NYC's dinosaur museum is getting a major addition in 2020 — here's what it looks like

The American Museum of Natural History (AMNH) is known among New Yorkers as "the dinosaur museum."

It's the gorgeous old museum that Ben Stiller explores in "Night at the Museum" — the one with room after room of hulking dinosaur skeletons:

Even if you've never been, you've probably heard of it. The museum has existed in one form or another since the 1870s, which means it's coming up on a big birthday: 150 years! As such, the museum's board is embarking on a $340 million, 235,000-square-foot addition to the already sprawling museum. 

Plans for the addition were announced on Wednesday morning in a press conference. Here's what we learned.

This is the current model for the new "Richard Gilder Center for Science, Education, and Innovation."

The project's chief architect, Jeanne Gang, demonstrated the model during an event at the American Museum of Natural History on Wednesday morning.

Rather than focusing on one particular subject, the center instead focuses on education.
