I realise this is quite challenging, even for experts, and I would not expect an identification to species level, but it would help me tremendously if someone could confirm that (some of) these are indeed bits of foram/ostracods. Perhaps someone could even indicate the environment? Benthic? Marine? Freshwater? brackish?
Thanks for your help!
I do not recognise any of these fragments as ostracods. Any ostracods that large would most likely be freshwater and very thin shelled, these look like well calcified shelly fragments.
I agree with Ian. The rectangular one on the right may be a gastropod shell fragmant.
No, I can't see forams or ostracods but definitely looks like inoceramid fragments. usually calcite or aragonite. What age are your sediments?
Dear Jhon, Please attach higher magnification images of red encircled specimen.
The large, thin and somewhat curved chunks suggest gastropod fragments. I don't see typical Inoceramus prisms. The top specimen has the shape of a Cibicidoides foram, but I see no sutures. More detail of both sides of that specimen is needed.
Dear all - thank you for the replies; again I realise it is a tricky question; still your information is very helpful.
We are in the process of obtaining additional material from the same core interval. We are hoping for better examples and higher magnification images.
If you are interested in forams and ostracods I would suggest looking at the finer fractions; 63um and 250um should concentrate these. Be as gentle as you can with any processing!
Dear John,
As most of the colleagues said the quality of photograph needs to be changed and give the opportunity to enlarge it. at this level it is so difficult to say some thing except for some fragments that are very similar to gastropod fragments. please take a very good picture for better identifications.
Cheers!
