Dinosaurs, Bones Cavort in $185 Million Science Palace

The base of the Perot Museum of Nature and Science’s undulating roof has broken stone slabs and concrete shafts. They might be ancient bones bleached by the sun.
The main body of the $185 million Dallas museum rises in a 170-foot-high cube of blistered concrete. It features a big gash that is crossed by a glass prism. (At night, visitors inside can be seen gliding smoothly up an escalator.)
