Here's a strange one. I found plentiful piles of what I thought were casts and internal molds in the iron-rich St. Mary's clay of Virginia last year. Loose clam fossils riddled blocks of talus. I was able to wiggle some out of their ancient resting places without s much as scratching the matrix. Generally that's because the shell disintegrated, leaving a void between the mold and the cast. If you look closely, however, what looks here like an internal mold isn't. The sculpture on the surface is clearly the outside of the shell. If it were the inside, you would see round protrusions where the ligament attached to a depression in the shell, not concentric ridges. Shown here is the most distinct of my specimens, but not the only one. Any thoughts? Mercenaria campechiensis, Miocene, VIrginia

I found this weird looking rock yesterday on a man made beach in Ruwais, Abu Dhabi. I have never seen anything like it here in the UAE. It appears to be a pieces of bone in/on top of some hardened clay. On the underside there are small shells stuck inside. I would be glad to find out more about this mysterious rock.

Septarian nodule aka lightning stone. 50 = Million years old. clay cemented into siderite. cracks filled in with calcite. Lake Michigan. only know in a 15 mile stretch. 1 3/4 inches. as found, hand sanded and polished. The red may be rust?

ESCONI recently announced a field trip to the Starved Rock Clay Pit in IL on 8/17. The layers are, from top down: Mecca Quarry Shale, Francis Creek Shale, Colchester No. 2 Coal, and paleosol. I was lucky enough to see the post in time to get on the list before it filled up. Anyone else here going? Also, I know ESCONI has been there before. Have any of you been there previously and have any tips you could share? This is my first trip to a quarry so I'm not sure what to expect.

I am wanting to remove this shark tooth for photography purposes, but it is attached to the display case via some putty-like adhesive. I haven't tried poking at it in fear of damaging the tooth (which is quite brittle), but it does appear to be somewhat hardened, although I may be wrong. Does anyone know how to best remove putties using household materials with minimal damage to the fossil? Any help is appreciated.

I recently went to the Isle of Wight and when I was hunting at Yarmouth beach, I found this on the foreshore amongst the pebbles. The imprint is about 1cm long. Any help you can give would be much appreciated.

I'm reading a 1960ish report on a formation near me (Bloomsburg). Among other interesting things it says "The most effective method of extracting the fossils from the claystone is by crushing in a crusher in which fine particles drop out so that they do not constantly undergo breakage." Can anyone elaborate on this process?

In the next week I have some time off work and i've been thinking about having a go at making a clay sculpture. Still undecided what subject matter to use. Doren has given me some helpful advice: an obscure creature from the ancient past, or a transitional animal, both great suggestions, but i'm still open to more specific ideas. So, please post me some images of the weird and wonderful. My clay is ready to go on Monday, and I will post some pictures of what I end up making however it turns out, even if it looks like my dog has made it.

Hi everyone, Should've posted these a LOOONG time ago, but me being the lazy guy I am I forgot to do so till now Anyways, here goes. These were all found by me (/my family) in the Carniol clay banks in southeastern France. They are (heavily for some) pyritized. They are from the "Gargasian", Aptian stage, Cretaceous. Would love to hear the species name of them. Genus is still fantastic. Thoughts? Thanks in advance, Max #1:

Hi all, Here are some fossils I found at this summer in Carniol, and I would like to know what they are. If the species can be said that would be fantastic. So, the fossils are all from Carniol, France. They are from the "Gargasian", of the Aptian stage of the Cretaceous, some 120'000 years old. Looks like they're all pyrite-replaced. I believe they're some kind of cephalopods, but I'm really not sure. What are your thoughts? Thanks in advance! Max

It is in the Changxing island of Dalian, a port city located in NE China, somewhere near Korea. The calcite/dolomites seems to have some scattered trilobites pieces. But the dolomite and clay layers stack up alternatively, which is not supposed to be marine face? BTW, the rocks are supposed to be of Early to Mid Cambrian period. I can not tell the speices of the trilobites. I do not know if they are heads or tails.

So I’m kinda a metal detecting guy... but I keep finding things that kinda stick out like a sore thumb that are (non metallic).. actually my son found this one flooded lake in northwestern Ontario Canada...at bottom of a eroded clay bank almost on the beach... looks kinda like a horseshoe crab..trying to get some better pics... with the naked eye you can make out a segmented tail (everything really stands out when it’s wet but not sure if that’s a good idea?) any ideas?

Folks, I need an archival consolidant that doesn’t dry glossy. The problem is the plant material I want to protect from flacking is sorta clay/soft shale. Even 5% w/v Paraloid in acetone is giving a glossy appearance. Not too bad on the fossil but looks horrible on matrix and fossil. In fact to increase contrast I like it on the fossil. Coating just the fossil isn’t an option. @Ptychodus04 @RJB @jpc @Harry Pristis

The person who owned my home before me left quite a rock collection around my yard. I seriously thought this was a cow patty when I first saw it. But upon closer examination it was just a weird, oyster shaped rock in a grey limestone like clay. It has shell casings around a few of the ridges and seems to have an oyster like shape. It also has small clear crystals that crust some of the ridges and crystalline matter mixed into the grey sludge clay its encased in. It weighs a lot, so I didn't think this was a fossil, but a friend who has more experience with fossils thinks its a fossil. I might upload some better pics later after I charge my camera.

Hi all, Earlier in spring, i had to organise a field trip to "les Vaches Noires" cliffs in Normandy for my association. I decided i should do a trip earlier solo (in february) to see how it had evolved since my last visit. It happened to be kinda useless since with thaw and heavy rains it had evolved so much between my 2 visits... Epoches covered are mainly jurassic (caloivan and oxfordian) but also cretaceous (cenomanian). For pictures of the site itself, you can have a peek to Nala's recent report here : On first visit, i didnt find much that worth mentionning beside a bunch of oxfordian echinoids : nucleolites scutatus and a big ammonites (a bit worn out but still) from oxfordian also : Perisphinctes sp The club trip happened to be much rewarding : In the callovian clay from the beach, i found this nice pyritized Quenstedoceras lamberti On the lower part of the "cliff", i managed to find this one : Quenstedtoceras messiaeni ? and also that oxfordian big gastropod : bourguetia sp Also put my hand on a few complete echinoid spines Paracidaris florigemma spines : On the close up of the bigger one you can see the quality of the preservation : As usual, more samples can be found on my TFF gallery (i also added 2 specimens from 2017 i hadn't shot yet) or on my flickr :
