Hello again my good friends. I did a petrographic thin section in a marine consolidated sediment, and i found some elements that seems to be microfossils. It is worth noting that these sediments are in a mandatory-way marine since in all of them are marine bivalves fragments. I also was unsure if put this here or either in the microfossil zone of the forum, leaving it here because it is an ID question. For each I'll leave a views in PPL and XPL. Hopefully someone may be able to recognize them at least broadly, and tell apart them from being forams, big diatoms or even algae. Greetings from Chi

I have two specimens, both apparently of the same species. They are both approximately 0.5 millimetres across. They are perfectly circular, with lines radiating from the centre and rings of alternating colours (possibly representing growth lines). One specimen is photographed dorsally, showing its circular shape, the ot

Location: Eocene, Keasey Formation NW Oregon. Length: 567 nm I've been using the following resources: 1. Microfossils by Armstrong & Brasier, second edition 2. ANSP Diatom New Taxon File 3. JSTOR research data base The item of interest is center image (5 mpx file), lighted bt 5600K sidelight, 10X objective. I have a sample gastropod encased in Keasey mudstone (formation can be from 1000 to > 10,000 feet in depth), and thought I'd scape a tiny bit of the the mudstone on a slide to view under my compound scope (use for solid speci

I must confess, I have no clue on this one. Found this in a dry creek bed yesterday near Silver City, NM. There are small brachiopod remnants (pieces) in the same rock. Thanks.
