Cenozoic invertebrate exhibit

[ghanley@xxxxxxxxxxxxxxxx (guy a hanley)]

I have a question regarding Cenozoic invertebrates that I would like a
number of opinions about.

I am currently working on a museum exhibition class project and would 
like some input as to what could be the focus of a cenozoic invertebrate
exhibit of approx 2500 square feet. I know that during the Cenozoic 
invertebrates gradually took on a modern look, but what could be some 
ways to present this to the public?  I do not want to give much 
information away as I am looking for just some general views on what 
various paleontologists see as important in the rise of cenozoic 
invertebrates.  What specimens would you put on display, and why? I 
have ten multi sized cases to work with, along with lots of wall 
space, although a very limited budget.

Any input would be greatly appreciated!
