A Couple of hours well spent...there are dinosaurs everywhere and well displayed. This is a must visit for anyone visiting Pittsburgh or are a long time resident.
Amazing that there are actual dinosaur bones. Don't forget to look up at the dino birds over head. All displays were well signed.
As well, there was a display of 50 of the all time best National Geographic photo's, with the back story.
Plenty of street parking. Cost us $20 but there are several discounts available . (SR citizen, AAA, military etc.)
