Hi. All these are out of the ordinary finds for me and I need some help with IDing. I think I know, which means I am wrong and need help. Thanks as always for any feedback. 1. 100% retile tooth. It stinks that it is all beat up but I will take it! I am thinking croc but maybe plesiosaur 2. I believe this is a reptile toe bone? Anyone know what type? it a little over a half an inch

So.....I was splitting my last piece of Pennsylvanian stark shale member, between Winterset and Bethany Falls limestone from a 2x2' 2" thick piece, I found some cool conodonts, a lot of scolecodonts, and amassing a pile of split shale, when I came upon yet another listracanthus/fish spine, about 5-6cm in length and very slender (2-3mm in width). I have both positive and negative pieces (depicted here). I scan all of these to see the pattern, faint impressions of a wider segment (as seen in photo 6 ), and in this particular specimen noted the shiny black cracks and creases surrounding the fossil. I see this very commonly in shale (and my understanding is it reflects rapid cooling of heated material?). In addition however, I saw what simply appeared to be conglomerations of, for lack of a better term, "worms" (Circled in blue in photo 2 and red in photo 6). Now stay with me on this one! Under microscopic evaluation numerous ''nematode" shaped objects adjacent to the spine are present, measuring 0.3-0.8mm in length are noted. Most are broken but there are some mostly intact. Several demonstrate fine "annelid" rings, (denoted by arrows) but I don't think these are annelids? At first I thought the preservation was too good to be real, but I have denoted numerous impressions in the shapes of worms, even to the point of the "rings". In reviewing nematode and annelid taxa, I don't see any mouthparts to make these polychaetes, and found reference to "ringed" nematodes. I hope someone can confirm or tell me if these are something else. I have placed circles (blue and red) around the groups, and arrows on salient features of impressions and the worms themselves. Also labeled a couple more intact individuals with an "N", but most are broken. If this is a reasonable observation, then this is one of the coolest things I have ever found!!!!! Fingers crossed I am on the right track!!!....Worst case, it is a plant piece with adjacent plant nematodes, which are very common nowadays and worst worst case, I am totally off track . There are 13 photos, with some seemingly one image but if you look close, they are separate if that helps. as always, thanks all!!! Have fun with these and let me know!! Bone

My guy found this while searching with a 365 nm uv lights for sodalite on a beach in Algoma WI. Lake Michigan. Can anyone offer a place for me to look for more information on what it could be? It is a 6 inch by 6 inch limestone rock. The object it 6 inches long and almost an inch wide. The backside of the rock has no fossil presence. The picture with the blue in the background is a 365 nm shortwave uv light. Thank you for looking

Hi all, I have been going through some of the coprolites in my collection in order to catalog them. I have two different specimens that have fish spine and scale inclusions. They are from Waurika, Oklahoma (Permian). 1. I want to verify that this is a fish spine. If so, could it be from a Xenacanthus?. Does anyone know if Xenacanthus had scales? The coprolite contains numerous scales. Of those that are visible, this is the best preserved. 2. This coprolite has a different type of fish spine. Any idea what type of fish it is from? That may be a tooth poking out above the spine. Based on the size of the coprolites, I'm assuming the coprolite producers were feeding on fry. As always, thanks for you help!
