The Pittsburgh museum is among the last major natural history museums to update its dinosaur collection to reflect current scientific thought.
In movies and some museums, for example, sauropods often are shown using their long necks to grab leaves from trees like giraffes. Recent computer models showed the bones in their 40-foot-necks weren't built for moving their tiny heads much above their shoulders. So, they more likely were grazers.
Ehem... :-)
DeWalt, the Carnegie Museum director, said the museum had long wanted to
remount the Carnegie's dinosaurs to reflect the new science but didn't have
the space.
