These Middle Eocene Epoch (Lutetian Stage of the
Palaeogene Period, Cenozoic Era) fossils just arrived so the images were quickly taken with the microscope using 40x magnification. Since they are relatively three dimensional some of the images are partially out of focus.
A website link is below that can be used to help identify them. The site is comprehensive with a lot of gastropods that will take a while to look through to match what fossil is what.
Fossils are from Fleury-la-Rivière which is located in the French region of Marne, southwest of Reims and northwest of Epernay.
This
French fossil website is an amazing piece of website development and paleontological data that was written at least 5 years ago. The PHP/SQL search method is nice that allows visual sorting on 1543 stored specimens.
Thanks to Michael Hesemann of
http://www.foraminifera.eu for these specimens.
