Location is in Missouri The area is dated to the Pennsylvanian Formation: Muncie Creek Shale I assume this could be some part of a fish, as I have found other parts of them inside a few of the concretions from the Muncie Creek formation such as cartilage, or it could be some sort of crustacean part but I do not know what this one could be.

I’ve had these in my substantial pile of ??? I saw a recent post that looked similar and pulled these three out. Roughly 1/4 inches. Are they drum fish or concretions or ??? Thank you

Location is in Missouri The area is dated to the Pennsylvanian Formation: Muncie Creek Shale I was cracking Phosphatic concretions and this baby popped out! I was excited and thought I should share and ask what it is! I believe it is a cartilaginous fish spine, but I have little knowledge in such topics. Ps Information on good glue to glue together the cracked piece is welcomed!

Is this even a fossil? Ichnofossil? I'm stumped by this weird pattern. I found this ironstone in my parents' gravel driveway. Gravels were recently obtained from the local sand pit company here in Salina, KS., so I'm pretty sure this stone was transported in the river from Kiowa or Dakota formation (Albian) before being deposited.

Location is in Missouri The area is dated to the Pennsylvanian most likely Raytown, Wyandotte Limestone Formation I have collected a lot of concretions and here are a few of which I have no idea what they could be My possible hunch is that some of these could be Fossilized Cartilage? Was really interested in knowing what this one was

Found possible bone after Cracking open limestone concretions! From Missouri
Samurai posted a topic in Fossil ID
Location is in Missouri The area is dated to the Pennsylvanian most likely Raytown, Wyandotte Limestone Formation I usually collect a few limestone concretions from a rock pile I go to and a few pieces of what appears to be bone popped out! Unfortunately when it did crack some of the pieces went flying and were unrecoverable While I do not know if it can be identified, I can hope it can somewhat be recognized. In the area I have found fossilized Cartilage through my Concretion cracking adventures and have found teeth from specimen of Eugeneodontida in the area. I also have come across the usual Brachiopods, Crinoid stems, Bryozoans, Rugose corals and petrified wood in the area. I believe this is some sort of fish bone, as to what it was? I have no clue. Below is the left side of the concretion

Hi I would like to ask if this is a concretion? The age should be Ordovician

Hi! I opened up this small concretion this morning. It looks like there is something inside, but I just can't make it out and I guess it could be anything really. Maybe some of the more knowledgeable people can see something. Was found in an area where I have found an ovulate scale. The concretion is blackish while the matrix it was in is a light Grey.

Hi there! These two rocks were found in the Aguja Formation. Wondering if they could be coprolite, concretions, some kind of scutes (unlikely), or meteorites? Material from the Aguja formation is very foreign to me, so I’m at a loss! They are rounded at the top and flatter at the bottom. Found amongst very large dinosaur bones. Thanks very much! Lauren

Something that looks like a fossilized bone. Got it out of a rock I split open, the rock in the pic with the green arrows pointing to where I extracted the thing in question. Any ideas?
-
I found these in a creek near taughannock falls (Tompkins county, NY). Are these concretions? Do they possibly contain fossils inside? Thanks! 1. About 25-30 cm in diameter 2. About 40 cm in diameter, with an interesting protrusion on a side

While out in the Puerco, I smacked open a concretion to find an unfamiliar pattern. Any thoughts or ideas are greatly appreciated. The specimen is from the Upper Cretaceous (Turonian) Carlile Shale. It is layered and each layer has this pattern. I currently do not have a measurement but will do so. Thanks for taking a look.

I'm guessing it's an iron concretion and not a fossil, but I would like to make sure. I have never seen anything like this shaped like a spikeball or flower, except in crystals. Fossil or not, I took it home because it's so interesting! Dakota formation and early Cenomainian. This formation are known for fossilized plants, leaf imprints, and petrified woods.

Found in Purse SP, Maryland . Need help identifying

I live in Northwest Indiana and my mom found this concretion. One side of it is fossilized though and has these indentions in lines. Any help identifying would be greatly appreciated. Thank you.

Just some of my concretion landscaping. They were all found in Middle Tennessee. I’m curious what other kinds of fossils may occur in them besides gastropods? I have found several that nature cracked open containing Gastropoda.

Amateur alert: i am NOT a professional paleontologist; I am a semi retired therapist who happens to be a paleontology hobbyist. I've seen several things advertised as gastroliths, and the prices seem easily doable. But HOW in the world is a rock determined to be a gastrolith, and not just a smoothish-rock that's a bit worn? A rock that has been inside a prehistoric animal (not just dinosaurs, I'm guessing?) is WILDLY cool, but a smoothed and tumbled rock is not.

My extraordinarily gifted fossil finding son found this in the bedrock of Brushy Creek (Williamson County, Tx.) and I can’t figure out what it is. Apologies for not using a proper scale or for poor picture quality but it is ~2’ in diameter and has well defined concentric rings. My son would love to show anyone in the Cedar Park area where it is and will offer a free Moonie’s hamburger to anyone who can help solve this mystery. Any help is greatly appreciated!

I'm sure I've seen something like this before, but there's a fossil-looking thing on the back.
Pleuromya posted a topic in Fossil ID
Hello, I found this rock, and it has this dipped area with a kind of pattern (I think it could be a concretion), and there's this fossil-looking thing on the back. Is anybody able to ID this? Thanks.

hello together, I saw this in an auction and am wondering if it may be something of interest? The blackish parts where it is broken looked somewhat bone-ish to me. No info but estate sale in the USA, 7.5” long, 5.5” wide and about 2” tall. Weighs 3 pounds Any ideas? Thanks and Best Regards, J

Found this at a undisclosed spot near Ventura, also found a large fossil shell deposit potentially from Pliocene. Will post pictures if people want me to. Btw if you have any clue or want pics of the other side of this please comment!

So, as a 12-year old fascinated with fossils, dinosaurs, etc. I found this and assumed it was a fossil egg. As I am much older, I tend to think more of a concretion, but the shape, and little kid in me says "yolk" but the adult says concretion. Again, found in St. Louis county along creek. Interesting none-the less?........... stay healthy! Bone

Dear friends, let me submit a sample from the alluvial sands of Kyiv, Ukraine. Please help me decide: is it a concretion or a fossil, and if it is a fossil, what could it be? May be, it is carbonized wood? As I know, Cenozoic deposits are possible here in Kyiv. In the Paleogene, the territory of Kyiv was covered by the sea (here the bones of the Basilosaurus were found), since the Neogene - land. I applied vinegar, and my sample does not respond Thank you in advance for the tips!
