sorry if the images are not clear as i took it by my digital camera through the eye piece of the binocular microscope. I have no camera attached to microscope to get better images. These species belong to K/Pg successions of the Farafra Oasis, Western Desert of Egypt as studies for my PhD.
I agree, better images are needed. However, from the small images I may guess a form belonging to Glomospira?????? But it is just an attempt as better images are missing.
