Hello, I have these stingray teeth that I haven't been able to identify. I only know that they are from Khouribga phosphates (45-70mya). Any ideas? Thanks in advance!

In this post I am going to show you a couple examples of fish related fossils that are found at Mazon Creek. Many of these are my finds and many are from my fossil mentor. The pics are zoomed up, I apologize for that, but I mounted my fossils (pairs) on white cardboard, so I do not want to pull them off and have to reattach them. First up is a lamprey - Mayomyzon pieckoensis. This lamprey was collected at Pit 11. Next up are a 3 examples of the Jawless fish- Gilpichthys greenei . These fish were found at Pit 11. Now I do not know if these names are still acceptable, but when I first started they were. These fish were found at Pit 11. Acanthodes marshi Acanthodes beecheri Here is a nice paleoniscoid that was found at Pit 11 and was ID’d by Dr. Dave Bardack, I believe the correct name is - Elonichthys peltigerus. This is a Rhabdoderma exiguum - Coelacanth. This fossil was found at Pit 4, in the area that I always called “Across From Pit 4”-(AFP4). Here is another nice Coelacanth- Rhabdoderma exiguum with a little coprolite. This piece was found at Pit 11 and I acquired it last year in a collection that I purchased. Here is another example- Now here is an odd one, it is called a Pipiscius zangerli. Many older collectors called it the “Push me- Pull me fish”. This second pic shows what should be the mouth. Now I know they are not classifying these as larval lungfish as they did when I first started, but I wanted to show a couple anyways. Here is Esconichthys apopyris. The first example shows multiple individuals. The next 3 are individuals. With this example you can see why collectors call them “ Ghosts”. This next piece was identified by Dr. Bardack as a fish head, but unknown species. This was found at Pit 11. This next piece I had brought with me to one of the Mazon Creek Open Houses at Northeastern and showed it to Dr. Bardack. He identified this as Acanthodian fish scales. This piece was found at Pit 11. Here are a few nice fish scales found at Pit 4 (AFP4). Here is a piece that I have identified as an Orthacanthus sp. tooth. This piece was found at Pit 4 (AFP4). Here are a couple Palaeoxyris. These pieces were found at Pit 4 (AFP4). Now these next pieces, all found at Pit 11, are described as either fish or amphibian eggs cases, either way they are very cool fossils. Mazonomaya helmichnus. This last piece is a spiral shark coprolite, not my best example, but one that I just came across. I also could not locate my Vertebrate Fossil of the Month find to post. Again these are some examples, I hope you enjoy them.

Hello friends, a while ago I published some photographs of my fossils and they gave me the good news that they are real. But, now I bought others, exposed them to the microscope and I would love to know your opinions (the quality of the images and videos is not the best, sorry). The specimens are very small, the fish does not measure more than 5 cm and the pygidium of the trilobite measures much less and I don't know what species they correspond to Proyecto sin título.mp4 Proyecto sin título.mp4

So I found this bone. It was found in North Texas, woodbine formation, Ive been discussing this with my friends. They believe its fish. One of the friends believes it might be Ceolocanth since he found a few pieces out here in different locations. I can find pics of anything that looks like it. It has some interesting features: 1.What appears to be enamel or iron scattered around the bone. Its shiny. Looks like enamel but some of the iron out there can look the same 2. It has "grooves" or lines that seem to go along the edges. Could be remnants of teeth, could be bites or claw marks, could be arrow head sharpening marks for all I know. Thanks for the help

Every year, I take some time out to collect the Burlington Formation (Mississippian) of SE Iowa. It is about 70 ft thick in the area I hunt and the limestone is a coarse-grained rock made up mostly of crinoidal debris. Usually, my goal when visiting is to find nice examples of crinoids and brachiopods. But lately, I have taken interest in the primitive shark teeth that exist in the upper few feet of the Cedar Fork Member of the Burlington. So late summer, I threw five 25 lb rocks containing evidence of Chondrichthyan teeth into the back of my pickup to process this winter. Here is an example of a rocks I have yet to process. Notice the black specks on the surface. This is what shark material looks like. Most surface teeth are worn and not worth collecting. The pristine teeth are inside. So, the next step is to break the large rock into smaller pieces in hopes to find a keeper. I use a vice to break off pieces. If a hammer is used instead, the vibrations destroy many of the fragile specimens. Every small black specks must be explored to see if they are the tip of a nice tooth. 90% of the specks are nothing but fragments. But every tenth one makes investigation worthwhile! Junk: Junk: Success!!! So as not to overwhelm everyone, I am going to show my finds in a few different posts. Images of Burlington fish on line is marginal at best. Consequently I will provide more examples than I normally would. Here are a few teasers for today.

My first attempt at prepping a fish fossil from Caithness.
James_R_V posted a topic in Fossil Preparation
I have finally finished preparing a Fossil lungfish (Dipterus valenciennesi) I found at Achanarras quarry, Caithness, and I though I would share the result. It took me about month to prep it using a dremel 290 engraver. I am pretty chuffed at how it has turned out. I managed to preserve most of the details of the fossil including fin rays.

Oxford clay, Peterborough Member, Jurassic, Callovian, Whittlesey in Cambridgeshire I collected this a few years ago, and I'm unclear whether it's a large cephalopod hook, or part of a fish, or something else entirely. Any assistance would be greatly appreciated.

Hello all. Quite a time back I found this shiny black thing in a piece of Brush Creek limestone. I had tentatively identified it as a trilobite free cheek part. However, a trip to the museum has the invertebrate paleontology department telling me that it's not for two reasons. While similar looking as a free cheek, the top portion doesn't match It's way too big to be a trilobite from this time period. I do agree with both assessments. It's twice the size of a typical Kasimovian (Late Pennsylvanian) trilobite from here. So, any fish part or tooth experts here? Perhaps this matches something that someone has seen. The connection at the junction where it turns into a point is interesting to me. Much more detail:

I assume this is some sort of bone either from a fish or some sort of other specimen. It could be a spine of some sort but I am extremely doubtful -

Hello, Any idea what this might be, where from? Possibly a madagascar fish nodule? The seller just says "probably cretaceous", doesn't seem to know much else. 13cm length. Also while I'm at it, can I ask if any part seems restored or enhanced? Thanks.

Hello, Is this fish fossil real? Listed as Pteronisculus from Madagascar, length 12cm. Any apparent reconstruction or fabrication? And how complete is it? Looks like the tip of the head may be cut off. Thanks.
