We also lost the beautiful museum at University of Michigan, replaced by a new one sharing space with other university departments. It's 'state of the art' but the beautiful collection of Paleozoic/Mesozoic dioramas have been mostly removed. It's an architectural demotion in disguise.
Michigan State University suffered an even worse fate. The old, quirky, but still informative hall of evolution in the basement (with its folk-art-ish equivalent of the Zallinger murals) was completely removed. More space for temporary exhibits I guess...they took the heart out of the place.
I visited the AMNH for the first time a few months ago and felt a lot of relief seeing mostly intact older exhibits, which pack in the *actual artifacts* and *physical dioramas* instead of a bunch of TV screens and blown-up illustrations. This is especially true of the zoology/anthropology parts of the museum, but of course many of the famous early 20th century dinosaur mounts haven't been tampered with too much.
I am not happy with how the great museums of people's youths (which often remained pretty unchanged for a long time) are getting revamped so heavily. I don't understand why the trend in natural history museums is to display less and less. Big art museums get to display so many pieces that you'd have to visit 7 times just to even see them all. Natural history museums have more 're-visit value' if they have more things on display, and it gives people a better picture of the evolution and variety of life to do this. Sure, everybody wants conciseness and a coherent narrative for the halls, but I think that insults a lot of people's intelligence. Grab the average schlub off the street and ask him how much he understands from the labels at the Metropolitan Museum of Art. So what if our museums' labels have tough words like "holotype" and "squamosal"? So what if it's just a dense collection of fossils and intricate dioramas? It just gives people something new to see and learn every time they come back, and adds respectability that critics often lament is missing from nat hist museums.
