Greetings!<br>
<br>
I am working on some Pleistocene samples from the Gulf of Mexico, and I am struggling to accurately identify this nanno (pictures attached). The magnification is 1000x, and the specimen is the large, thin ring to the bottom right of the cross-hairs. I won’t
bias your interpretation by telling you what I think. Thank you all very much!<br>
