Hey, do you have any information on this specimen, location where collected, genus, etc? If you do we can add it to the online museum. Thanks!
Added what I believe is correct I.D., It’s tough to I.D., let me know what you think.
@samantha-ocon – can you chime in with your foram and Florida knowledge?
I’m thinking this might be a nummulitid based on the shape of the test and internal chambers.
So this is a Nummulites sp. Classification, starting with Kingdom, would be Protista -> Foraminifera -> Globothalamea -> Rotaliida -> Nummulitidae -> Nummulites sp.. This also indicates that the source rock was most likely the Ocala limestone and Eocene in age.
I don’t seem to find a photo of a Nummulites shell like this on the net. Any ideas of where to look?
@delwin-glasner – Most images of Nummulites are of cut specimens so you can see the internal chambers. I was able to find a dissertation and if you go to the very end there is a complete specimen. I used the search feature (ctrl + F) to find all occurrences but if you head to like page 147 and scroll through the images you will see one. Maybe @samantha-ocon has some other suggestions.

I have some cross sections, but I’m unsure if I have any good pics of the external test. I can also double check my phone for some pics of when I was picking.
Corrected to Nummulites, Eocene and Ocala
