I bought a large box or various fossils that I believe were part of someone's estate off of an online auction site. This is a portion of trilobite and unfortunately there was no label to go with it. Hopefully there is enough detail in the picture for someone to narrow it down a bit. Let me know if better pictures are needed or a close up of the eyes.or something else. Thanks

This sample is more damaged than the trilobites I usually find, but I would still like to ID it. I realize that this is likely the thorax of an Isotelus, since that is what I have been finding at this site, but this thorax looks a bit different than the others I have been finding - it looks a bit more concave to me, as opposed the more flat / convex thorax of the other trilobites I have. Also, there seems to be a piece down the center that looks to be from somewhere else, and not from this trilobite. Thoughts? I included both a dry and a wet pic, to try to show more detail, as well as a closer-up pic from one side.

Hi - this is my first post to this group. I found this partial trilobite fossil this past summer in Ordovician limestone near Eganville, Ontario, Canada and I am hoping that someone here can help me identify the trilobite species it belongs to. This piece measures 3.5 inches in length by a little over 2.5 inches wide and I believe it is the pygidium and most of the thorax (so a little more than half of the full trilobite). Also, it has a little over 1/2 inch in depth, so it is not completely crushed flat. I would have much rather found a full trilobite - and I do have a full trilobite that I found that I am having prepped, that I will post at a later date - but I am very happy with the size and condition of this sample. I broke it out of the rock in this condition - no prepping has been done to this sample. Any thoughts?

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!
