Something fun
There are six dinosaurs hidden in this interactive map. See if you can find them.
Once you find them, you can click on them to learn more about some of the dinosaurs that are part of the Carnegie Museum of Natural History exhibit.
Alternatively, you can click on the highlighted names in the list below or find the corresponding hot spot on the map to view that information.
Six of the map's hot spots will change to black and gold and correspond with the highlighted names in the list and the hidden dinosaurs.

The Carnegie Museum of Natural History's long-awaited $36 million exhibit
"Dinosaurs in Their Time" opens this week. The 19 dinosaurs are
posed in realistic environments. That means you’ll see
Ceratosaurus, a new addition to the museum, charging
after the birdlike Dryosaurus, and the 40-foot-long
Allosaurus trying to gobble up a baby
Apatosaurus, whose 80-foot-long
mom is guarding him with
her long tail swinging
at the attacker.
