I had a very late start tonight thaks to a landlord who needed to be straightened out, so I am only going to post a couple of these refs for now. Also, for those who asked about intro paleobotany refs, I don't really have any. I just kind of muddled my way through, but I had some help from a geology class at the FMNH and one book, After the Ice Age by E.C. Pielou (which if you haven't read and always wanted to be knowledgable about glaciation events-drop what you are doing and go buy).

This last one I found as a photocopy out on a table in the bio library at U.of Illinois and read on the spot. I am totally unaware of its presence as a journal in the Uof I collections so I was most lucky.
