Orbiculoidea capuliformis with preserved pedicle, Muncie creek concretion
Jaybot posted a topic in Member Collections
I recently collected some Muncie creek concretions from the Kansas City area. I had previously only found a few concretions, but this time I was fortunate enough to end up with about 10. Several had Conulariid sections preserved, which I was excited about. Back home, I cracked open the remaining concretions. One of them had a tiny little brachiopod, and I didn't think much of it. Later, looking at it under magnification, I was astounded when I found the remains of the preserved pedicle! This is where I am sad to say, that in my excitement, I forgot to take pictures of the fossil prior to me prepping around the shell to aid in id. Anyways, after prepping around the shell with a hand scribe, I was excited to find that it was also my first lingulate brach. Orbiculoidea capuliformis Sorry for making you read all of that, here are the photos: Scale is in cm. Here are several interesting articles/papers for anyone interested. https://www.diva-portal.org/smash/get/diva2:373816/FULLTEXT01.pdf https://www.researchgate.net/figure/a-b-The-brachiopod-L-chengjiangensis-represented-by-stout-pedicles-marked-by-numbers_fig1_24424671 Despite being small, there is a lot of potential with Muncie Creek shale concretions. I learned a lot about them, and their existence, here on TFF. @Missourian has found many astonishing finds, and I noticed that soft tissue preservation is prevalent in many of his best concretions. Hope y'all enjoyed this. Have a great day, and a great weekend -Jay- 9 replies

This was originally a rock that I thought looked like it was in the shape of a small hip bone or something. I collected it in Marlboro NJ a few years ago, but just recently got the urge to tinker with it. I started to dissolve some of the rock away. After about a quarter inch was removed I thought it looked like the upper half of a newborn or embryotic dinosaur that had been slightly crushed. I have been told it is just a concretion, but I am still convinced it is a baby dino. I have no idea how this would happen. However,. All the pieces are there Eyes, ears, nose, mouth, spinal cord, chest cavity, arms. I believe the large ear looking thing is the crest folded down. You can even make out little fingers and two lungs when looking at it in person. Let me know if anyone else sees this or if I am delusional.

I found this really cool looking fish which is most likely a Knightia, but it's preserved in ventral aspect. The rear portion of the fish is missing including the dorsal fin so many of the diagnostic characteristics have been lost, but I still believe this is a Knightia based on the overall shape of the skull and the shape of the body. My question is more of a matter of ID'ing bones, because the main reason why I like this fish is you can see many of the bones that the typical Knightia does not show. I can see two operculum, one on each side. The lower and upper jaw I THINK are visible which is kind of weird because this is a ventral fish. The "gill" pieces which are my favorite part of the piece I think are called branchiostegals correct me if I'm wrong. But with many of the bones I have no clue. If anybody has input about this feel free to post what you have to say, I'm all ears!

While rockhounding in the area of the Niagara Penninsula, I found an odd-shaped piece of metal about 5 inches beneath very thick, wet mud. The place in which I found the object was in a very shallow stream, which ran over sedimentary rock of the pre-Cambrian shield. After a closer inspection at home, I believe I may have found an iron-mineralized piece of a petrified wood, intertwined with two separate vines. A friend suggested it may be a rusty drill bit although I have doubts based on the location it was found. It is 3 1/2" long and 3/4" wide. It is heavy and seems hard like a metal. It is somewhat magnetic. It appears mostly brown, with spots of orange, and some light brown mud residue. I am assuming the vibrant orange colour is rust although there are also pale-orange spots which resemble the interior of a stick. Before cleaning the specimen, I would appreciate any opinions/advice. I am only able to attach two photos, but I will upload the rest in the response section. Any help is much appreciated!

Hello from Cyprus, this one I found near the old limestone quarry in moni area, again the heavy rain , when the mud sliding settled, it exposed a piece of it. 3m under the usual surface It is quite big and very well preserved. In the same wall I found also another kind of gastropod, corals, 4 kinds of bivalves. I will post on other threads soon. That wall consisted of beige/white earth and grey hardened sand like parts, still needed metal needle tool to scrap it off, of some specimens. Also most specimens are whiter that what I am used to find. Which i think it could be fossils, yet younger ones, like 80-100k years old?

Ok, as promised I will be posting some of my finds in Cyprus island, for ID, discussion etc but while in my "chamber of the million unidentified things" trying to get some decent photos and find similar online, I decided to take a small trip yesterday April 1st and BOOM I see this. (photos) is that a whole fish preserved like inside out and all? Or has mother nature pulled an April fool's day joke on me?? I wonder if I can see inside using x-ray.. I really want to find a doctor and try do that. Let hear it from the experts here 1st tho. I have cleaned the specimen and carefully removed what was surely aged dirt etc. I'm trying to get some more photos online, as I see here I am having a size limit issue. I case in the photos is not clear, at the "tail" part you can notice that inside there is this dark crystal like material, the one our ancestors used to start a fire and used it to make tools and weapons with. the two round "eyes" appear to have that material inside too.. which is confusing, coz tail and eyeballs are not exactly same material, then again maybe those are not eyeballs and it is upside down (because when u flip it, it resembles one sort of fish look, and when again, another one. a "fish palindrome" lol) or there is various stuff and materials inside, because outside you can see indication of dark almost black contents, and mostly those parts are mat and not glossy. Also in some places mainly on one side. u can see many brownish dots like freckles is it called?

I think it's a ceritops. The egg looks a bit squished. And the skin has a blue hue in places. I can see skin. Bone. The face, and eye socket. The right shoulder socket. Limbs. A placenta type skin covering separating the body from other parts of the egg. It's rubbery, or waxy feeling to the touch. The shell is fragile, but it was leathery what I found it. Somebody say to me. " oh my God, your rite. That's a ceritops fetus. In the egg. " . I bet there is DNA in this thing hey ,)
