Hi,
I don't want to over post, but this is my only venue for this. Here first is a nice big Pseudodechenella planimarginata pygidium that I like because it clearly shows 15 axial segments on the pygidium. I thought I had counted 15 on smaller ones, but they get blurry. Is 15 diagnostic for thei species?
Second is a nice Trypaulites calypso, which are quite uncommon (this is only the second decent one I have found). Third is interesting and I'm wondering if it might be a T calypso thorax. It was definitely in the same layer as the pygidium. I've not ever seen anything like it. I also don't know iff the shell manes sense as it is not in individual ribs, or it doesn't look it. It looks like there is more in the rock, but I'd be afraid to take my Dremel to it, I think. What do you think? Thorax?
