Fellow members, I have been offered this Ceratonurus. At first glance it appears to be well prepped etc. with no signs of obvious fractures etc. As one should be on guard when purchasing Moroccan material, I would like to seek counsel / opinions / another pair of eyes regarding this specimen which I have been offered. Can anyone see any signs of repair and / or restoration? Thankyou in advance, much appreciated. B30918C5-EF61-4985-9056-11F58396A942.mov B30918C5-EF61-4985-9056-11F58396A942.mov

Here are a few trilobites, damaged and partials that were found this summer. After cleaning these up over the last few days, I still am unsure of their identities. The first one I will venture is an Isotelus roller. Rollers always confuse me! It is from the Maquoketa/Ordovician and Isotelus are common. @Kane, @piranha 3. is also from the Maquoketa/Ordovician. Maybe not enough present to tell. The rest are from the Platteville/ Ordovician. 4. Popped out of the matrix during prep. It measures 2.5cm by 2.0cm. I count 9 thoracic segments. This is the back side showing a probable pygidium. Interestingly, the depression in front of the pygidium has a positive to it (saved) which makes me wonder whether it could be a hypostome. I will research further once I can identify the species, or at least genus. 2. Is a smaller trilobite, 2cm by 1.5cm and contains 8 visible thoracic segments, though the end is not complete. 5. This specimen is the real reason that the post was created. It has me completely stumped. Unfortunately a piece is missing. I did not see this in the rock until I began processing a different fossil. Hence the other piece is back at the roadcut that this was found at. Anyways, I suspect but not convinced it is a trilobite. The green dots in the first picture show the fractured area. The dark fuzzy area delineated by the red dots is perpendicular to the fractured face. It was hidden in rock until the Dremel exposed it, The exposed surface is very rough compared to other trilobites I have found. Because of this I was hoping to have a better understanding of what is within this rock before prepping further. Here is what I envision as a possibility Thanks for taking a look!

Found this fossil couple years ago. Just want to learn more about it!
