A fun place to visit, but if you're pressed for time I'd skip over the Natural History Museum. It's not bad, but I preferred the Carnegie Art Museum.
This part of the museum is what you would expect... dinosaurs, fossils, & things of that nature. Out of the Natural History museums I've been to, this one immediately seems like the best of them all.
One thing that standouts at this museum is that the fossils they have are actual dinosaur fossils. A lot of museums have replicas or cast-models of their dinosaurs. It's fascinating!
I decided to take 2 stars off as a personal preference. This particular museum is very kid heavy. They're everywhere. It wouldn't be bad if parents made their kids mind, but if you're not fond of kids... this is not the place to be. Kids are running around everywhere, screaming, crying, the list goes on & on & on.
