I have two items on which I am requesting opinions. These are from a dolomitic nodule from the Schoolcraft Fm. in the upper peninsula of Michigan. The first one I think is a pygidium of the trilobite Scutellum. (note there appear to be some other trilo"bits" surrounding it). @piranha, what do you think? Here is an image from Ehlers (1973) Stratigraphy of the Niagaran Series of the Northern Peninsula of Michigan that he has as Scutellum laphami.

Greetings, experts and seekers of expertise and knowledge. I posted an image of my first trilobite, along with a mosasaurus tooth and some images from the Ventura Rock, Gem, and Fossil Show, which took place last weekend. I posted it in Member Collections because it appeared to be the best spot. However, it seemed to have very limited views and comments, so I'm posting in the world famous I.D. section. I'm relatively sure that the little trilobite was correctly labeled, but it would be nice to have comments on that from the experts. I checked it against some images at trilobite.info, and it would seem to be from the order corynexochida. Admittedly, I'm very new to scientific naming, etc. Based on the time frame and physical appearance, it looks like corynexochida to me. It also looks like it is indeed a thysanopeltella (Scutellum?), as it was labeled. So is a scutellum a member of the order corynexochida? I guess I'm just looking for confirmation on the labeling, and of overall condition, prepping, etc. I realize that I could be all washed up on most of what I just said. I claim nothing but ignorance. Many thanks in advance. Cheers.
