And since one of the goals of this museum makeover is to cement its reputation as a dinosaur place, it’s worth saying that the actual main dinosaur exhibit could use some more overt dino cues. It is called “Evolving Planet,” and it is one of the best museum exhibits you’ll see. It tells, in comprehensible and even dramatic fashion, the story of life on Earth, from start to now, with a very pregnant pause along the way to show off all the dinosaur fossils the Field owns. (Sue will become a stop on this pathway, in a bespoke exhibition meant to display the T. rex in its surroundings, rather than as an art object; with a brave willingness to peel back the curtain, the museum lets visitors see Sue now through a plexiglass window, charmingly insistent on maintaining ferocity in an ordinary unfinished room.)
