“I have a variety of fossils available for trade. Extra specimens looking
for a good home. None are top of the line, but may be of interest to
fossil collectors. Included are Illinois worm traces, Wisconsin ocean
ripple marks, Indiana crinoid calyxes, large clams, Florida shells, a
Germany amphibian, unopened Illinois Mazon nodules, Midwest invertebrate
sets, books, and more. You can check these out on ebay under used name
blowfly2. All are listed for sale, but I am also open to a trade if
items are unsold.

Please reply if you have an interest. Let me know what you have to offer
as well.”
