Found on surface in area with numerous crinoid stem sections. Stone appears to also have stem cross-section impressions. Friend notes this specimen does not have the five-lobed feature of crinoids. Western St. Louis County, Missouri. Near Rockwoods Reservation. Rocky clay soil is tens of meters deep with egg- to fist-size rounded stones throughout. Is this a cross-section or a negative impression? Vascular bundles? If not crinoid, what?

Hi everyone, I am not a specialist in paleontology, I would like some help in identifying these 3 stones. I found them in clay from a marine environment dating from the Cenomanian... It seems to me that there is a bivalve, a vermiform fossil (?) and one resembling a degraded bone. I do not know well the paleontological discoveries of my region, I just know that there was the discovery of a vertebra of a marine reptile and the tooth of a sauropod. Thanks a lot for your help

I sometimes stumble upon these strange fossils which I like to call 'mini surfboards'. I unsuccessfully searched a couple of times on the internet and found no similar photos to help me identify them. They've all been found on the clay layer. They all have a very similar pattern . Their size is usually around 3cm (even larger sometimes).

Claiborne Amber (Cockfield Fm., 41.3-38 Ma)
Barrelcactusaddict posted a gallery image in Members Gallery
From the album: Fossil Amber and Copal: Worldwide Localities
1.4g translucent specimen measuring (mm) 16x15x10; one side presents an unbroken exterior, with slight remnants of sand, clay, and lignitic matrix. This material was recovered from the Malvern Clay Pits, east of Malvern, Arkansas. FTIR spectrum comparison of Claiborne amber to modern Shorea sp. resin points to the Dipterocarpaceae as a probable source for this middle Eocene-aged amber.© Kaegen Lau

4.1g rough specimen measuring (mm) 25x18x15. This is a section of a run, with successive layers grading from translucent to opaque; portions of the sand, clay, and lignitic matrix coats the exterior as depicted.

As a later summer vacation we decided to do a road trip - Tour de France. France having many interesting destinations and things to do and collecting fossils would be one of them. As we usually don’t plan our trips beyond a few days ahead also the fossil locations were decided on the road. But when reading about Carniol it became clear it was one we had to include. Other non fossil highlights of the trip were Bordeaux, the Pyrenees, Toulouse (great museum of natural history), Lyon and of course Pont du Gard. When finding out about Carniol I did some further reading on how to get th

This jaw fragment was found when washing clay that I brought from Carniol. Cretaceous, Aptian, Gargasian. On Reddit it was identified as Saurian and I was hoping (but doubting) a more accurate identification would be possible. Really happy with this find anyhow. more information about Carniol and my trip there

Please help me identify these finds from the bottom of a clay cliff in Warden Point, Isle of Sheppey a - 0.5cm thick, almost flat, smooth on the other side b - i think this is not a fossil but a handle of an old knife c - round in cross section d - this is hexagonal in cross section the remaining ones are all of the same kind and the beach was full of them, i guess they may not be fossils either but what are they?

Hello. I recently visited Chapman, KS looking for calcite geodes and I did find several. I also found these. I have no idea what they are. They were found in a layer of shale. They almost remind me of tubes of fossilized clay? The end shots are not very good, but they show beige layers. Is it possible that that clay was forced into voids in the shale maybe and then they hardened or fossilized? I cut the ends on a tile saw and the material was very hard. In one of the photo's, you can see where one of them was bisected by a thin layer of calcium carbonate (calcite) hot liquid at some p

Hello everyone. My son and i are both passionate about paleontology. During our research’s, we found these stones in red clay/sand with flint dating from Cenomanian (near Chartres, France). The stones were among the remains of bivalves and sponges. All the fossils found show strong erosion. Do you think it could be fossils or just stones? Thank you

Hey everyone, So this summer, like most summers, my family went to my grandpa's holiday house in southern France. Seeing that we had many days with nothing planned, I managed to convince them to go fossil hunting one day. At first, I wanted to go to Lacoste, a place known for its echinoids and gorgeous white scallops, but it turns out these quarries are no longer accessible. So instead we went to Carniol, which was a little further away. After only a few hours in the car we arrived at the village of Carniol. "Village" would still be considered being generous: there are no more tha

Was digging in vegetable patch in clay soil about 20cm below surface in back garden, south-east London, UK and found this little beauty! First fossil I've found without looking for one. I especially like the lower section of the right-hand image, where you can see the pattern is an imprint rather than a protrusion (not sure of the correct terminology!) Any ideas what it could be? I've provided a scale on the image. Reminds me of a worm! I can answer any questions.

I need to make some molds, best (cheap) source of molding material?
OregonFossil posted a topic in Fossil Preparation
Mostly small fossils (think less than 20mm, many 2 to 3 mm). Maybe a pound or two. Brands on Amazon, other sources? The molds would be used to photograph for fine internal and external detail from casts. I am clueless when it comes to this. -
I am new and I have no idea what this is. Can someone please give me an educated guest at least?

This cylindrical object came from my neighbor whose mother was an avid artifact and rock collector. She had no idea what it was or when her mother found it but it was a long time ago up in the area of Carey, Idaho, on her mother's private property. The object is cylindrical with a small sway toward the middle of it. It is 4' tall and approximately 2 3/8" at the widest point. It is stone or clay colored uniformly aside from the ends where it has a brownish gold tinge and shows circles in the center of each end. It is very heavy given its size and seems dense it weighs 1 lb 6.1 oz. Any he -
About 500m ASL, we had fun, found a clay bank and tried for shark teeth. In the end everything was too fragile, the shells disintegrated as we extracted them and the only solid things were the infilled burrows. Thought I had to share anyway... it was a fun time. https://youtu.be/ZOMRLKpItPI and some photos of the lunk we bought out... that is crumbling fast.

Hello everybody! In continuation of the Frozen Fossils and Frozen Fossils II topics this report covers fossil hunting in real winter, with excavating fossils from under the snow (@JamieLynn might be interested). The trips took place this week when we had a thaw with temperatures raising to +1-2 Celsius after a long period of frost (so that digging became possible). This time I visited the same site as in FF2, which is MUCH poorer than the one covered in FF1, but MIGHT yield more diverse fossils (which was unfortunately not the case).

Hey guys! so I recently went looking in an old local creek for arrowheads and came across a grapefruit sized clay rock. (Assuming it was clay due to the clay in the area) once I busted it open I got many voids and very small round objects. Any help will be much appreciated!!

Good evening everyone depending on where you live. I'm new to rocks and fossils and I wanted to see if anyone knew what this strange rock formation may be. I live in Central Michigan where the rock was found. Attached images. Thank you much!

Hi All, Thanks for having me here. Me and my girlfriend have recently discovered an interest in looking for fossils. Luckily for us, we have spent some time in Folkestone, England which we have discovered is pretty full of fossils in the right place. The below are a couple of finds from one afternoon down at Copt point while we were walking the dog. Any extra information about what we found would be very much appreciated. My uneducated guess is that all are ammonites except for the two specimens at the bottom, which I am completely unsure of. They all came out of a gault clay

I am new to fossil preparation, I really want to prepare this echinoid I found on Jebel Hafeet, Al Ain, UAE. I have started prepping it with a small needle, since I don't have access to any fancy machines, but I think I just ended up damaging the fossil. The rock seems to be a type of clay, not too hard. It might also be limestone, since the area is known for its shallow marine sedimentary rocks. Should I soak it in water? Or vinegar? Should I have a go at it with my dremel?
