I just went through my bag of trilobits from this summer. Most are identified. I am getting better with time!! Here are a few Small pygidiums, all between 1 and 2 cm. These small non descript tails are hard for me to identify. If there are ones that stand out, let me know, and why you think so! That way I will know for next summer's specimens. They are numbered. Thanks, Mike

This morning I was going through a bucket if Black Cat Mountain matrix a friend gave to me. I found this nice negative of a large trilobite Pygidium. I wonder if some one might know the species. Thank you

Found in Arkona, Ontario Age: Devonian Size: about 18 mm/0.75 inches Any ideas?

I am finally getting most of my trilobite parts identified but still need some schooling on this pygidium: It was found in the Platteville/ Ordovician in SW Wisconsin. It is 4cm by 4.5 cm In addition, these two plates contain what I thought were just pieces of Isotelus, but the more I looked, the more I questioned my thoughts. Agree or change the ID? These plates are 12 inches by 6 inches. The asterisk's mark where the specimens are.

I was going through some containers from a few years back when I returned to collecting, and it had a bunch of pieces I had collected from my mixed fill location (lower to mid Devonian). I came across this little pygidium. The squares are 5 mm x 5 mm. Going through some of the literature to compare photo plates from Ludvigsen and Lesperance, as well as scanning the Proetids in Levi-Setti and Whittington, there just didn't seem to be a perfect match. The axis sits fairly high on this one, a little like Mannopyge halli, but unlike the M. halli does not have the terminal nodes. The axis "points" downward rather dramatically, and has some apparent incisions. There is a small but distinct margin on the pygidium that made me think one of the Dechenella types. I've tentatively labeled it Pseudodechenella although I am not comfortable with that identification for this one. The Pseudodechenella I usually find don't have this very pronounced axial feature, and usually have a kind of smoother shell on the pygidium. I may be overthinking this, but I put this one out there for our Devo bug experts. Much appreciated for any help on this one.

Hi folks. At first glance, I labeled this cephalon an Eldredgeops but it doesn't compare well with other examples in the area behind the eye where the "dimples" are. There is also a sort of "horn" projecting from the upper rear portion of the eye. Just not certain about this one. Could just be deformation ? Then the nice size greenops pygidium. Wow, I'd love to find a complete one this size ! Thanks, Regards.

This is #8 and #9. Both were in the same split of shale. The larger one was barely visible, just 1/2 of the fwd center ridge. Took quite a bit of digging to expose it. I was pretty sure what it was, getting used to the little clues. Thanks again !

Found #6 last night. Only a small portion was exposed, I scratched the matrix away to expose the rest. I wish I had learned earlier what to look for more specifically. I am certain that I have overlooked more of what I am looking for than what I have found. Thanks again to all for you guidance, experience and willingness to contribute. Kindest regards.

Hey everyone, I thought that I would talk about trilobite anatomy. I have been using some complicated terms, and I want to make sure that we are all on the same page. So please watch the movie and enjoy!
