First of all, apologies for the image quality. I know flash can be pretty horrid but it's all I can do at the moment. Side-views will be found in the following posts!
I collected this (probably molted) trilo at Marjum pass in Utah a few weeks ago. The depth of the axial lobe and how the pleurae seem to flare up led me to believe that this specimen is on its back.
I only have a pin vise at my disposal and I don't want to ruin a good specimen with the incorrect equipment, but I wondered if anyone has heard of pin-vising Marjum shale. Would you use air abrasion? In that case I will save it for a few years when I can afford it (:
Thanks for reading, hope everyone's staying safe!
