Gastropods with calcite crystals from Oxfordian stage (163,5 mln years)
Svetlana posted a topic in Member Fossil Trades Bulletin Board
Hello everyone. I offer interesting gastropods with calcite crystals - perhaps someone will be interested I have a lot of them. Pseudomorphoses of calcite after gastropod shells of the genus Nerinea from Upper Jurassic limestones of the Oxfordian stage (Izyum Formation J2-3iz); 163,5 mln years. Ukraine, Donetsk region. I'm interested in everything - I invite you to private messages Have a nice day VID_20220122_135535.mp4 VID_20220122_135732.mp4 -
Looking for some info on this specimen from Eastern MO. Is this perhaps some sort of cephalopod impression partially replaced by calcite crystals? Thanks!

Hi all. I found some pretty cool boulders of calcite littered with crinoid impressions in a public park in Danville, IL back in late August, but left everything until I got approval from their park department to remove them. I finally heard back last month, but didn't get around to going until today. I found a few interesting things that I'll post when they're cleaned up, but I probably won't even begin the process until Thursday. In the meantime I took a photo of a trace fossil that was sitting near the top of one of the specimens. I can identify most of the things in the pieces, but am

Picked from mix of QT, QAL, and Eagle Ford gravels. I love calcite but it can be deceiving, not sure if this was replacement of something or naturally formed structure, appears to be fossilized something. Curious about the red, mineral staining maybe? Last pic is view from above.

I have no knowledge of this ammonite’s history. Does anyone have any idea of its type? It’s about 5 to 6 inches in diameter, a portion of it being fossilized with calcite.

What did I find this ammonite in? And need ID on calcite fossil.
Lone Hunter posted a topic in Fossil ID
Went to creek I frequent but went down to a part I haven't been to for awhile, had several good floods since. Much to my surprise I rounded a corner and the bottom of the creek was pale yellow as far as I could see down. As you see in the picture there was shapes carved out by water, and it was very thick in places, but it was soft enough to break of pieces and it was grey underneath. So is this a layer of shale? If so why is it yellow? This may be natural in Eagle Ford and I've just never seen it in this form, just looking around I spotted this ammonite and just plucked it out. So now wonder -
Hello everyone! I haven't posted here in a long while, mostly due to lack of finds. I dug this out of my collection, and wondered what it could be. It looked like some form of calcite, but has an oddly organic shape. I also noticed that it has some small fossils, possibly shells, attached to the bottom. It came from Al Ain, United Arab Emirates, near the foot of Jebel Hafeet. I am not sure of the age, but I assume it is Miocene. I have found many numulites close to the location, as well as gastropod steinkerns, and urchins.

It was late, my back against an old brick building. Light rain comin down. Felt a bit cold. Pulled up the coller on my trench coat. Wondering how long ive been standing here. I realize there is a glare on the street from the lamp post. I pull the brim of my hat down. Then I see her. I tell myself to stay calm,,,, keep cool. I take the last drag off my ciggerett and flip the butt onto the street. The orange glow snuffed out immediately. I study her from underneath my hat brim. I can tell she has been worked on before. I don't move. I keep studying her. I can tell that she

Found this in same creek by DFW airport, Eagle Ford/Alluvium mix. So has basic shape of an ammonite but really thrown off by strange pattern, not typical wear and each side so different. Just don't know what to make of it.

Parkinsonia parkinsoni (ammonite) Jurassic, Upper inferior Oolite Bridport Dorset. UK 6.5" The first photos I took a few years ago did nothing for this unique specimen. I found it difficult capturing the details and still think they could be better. The ammonite has many chambers preserved in calcite that glow when backlit. Calcite crystals can be seen growing inside some of the empty chambers. Fossil, mineral, crystals, art, science, love Happy collecting.

Hello, I found this interesting looking specimen in Port Charlotte, Fl. It is 2 inches (50.8 mm) long and 1.25 inches (31.75 mm) wide. It has teeny tiny honey colored calcite crystals in the segments and in the crack in the one end. I can see the crystals with a flashlight. I have many shrimp burrow casts but none of them are segmented, this is what it reminds me of though. Thanks for looking. Marie

Calcite clam shell matrix pieces for trade

I have some matrix pieces from ruck’s pit in Florida with some awesome calcite replacements And formations in the shells. I am open to all kinds of offers, including looking for other kinds of Matrix pieces, fossil fish and much more! -
Hello again, This is an interesting find found at the causeway in Tampa Bay, Florida last year. Looks like calcite covered coral or a sand fused fulgurite which I'd prefer to add to my collection, lol. What do you guys think? Thanks!

Here are some of the fish fossils I have found, the first picture are some bones that I was hesitant to call fossils at first because they where scattered on top of a pile, but after find several other clay pockets ful of these I feel pretty good about them being gar fossils. Can anyone confirm, the internet is not being super helpful on this one? The next two are encased in a calcite geode i picked up while picking through the overburden, I didn't even see the imprints until i had washed it at home. Any ideas of what they are? From what i can barely tell, there are more in the g

I found these in a large pile of dirt in a new housing development in Venice FL. I'm assuming they are calcite, but was wondering what type and what they are growing, incapacitated in. I found a lot of them and attaching 3 examples. They are holding yellow and growing on a charcoal, bulbuls rock. Thanks

Im still new at fossil hunting. Been looking at a few rivers small creeks here in Volusia county. I have also been searching the web. Still nothing comes up with hunting fossils and minerals in east central Florida. Volusia, Seminole, Brevard, Orange counties. You would think the st johns river areas would be a good place to search. If you guys know of any information that would be great?

My new Early Permian Reptiliomorph (Discosauriscus austriacus) fossil
autismoford posted a topic in Member Collections
I just added this wonderful specimen to my collection. The species is discosauriscus. Little is known about the species other than the fact that they were predators based off of teeth. They may of had electrospective organs. On this slab running through the head of the specimen is a thick calcite seam from where the rock was faulted and shifted. This was found in the Czech Rebublic in the Limnic Deposits. This is the first fossil I've purchased all the others in my collection I have found.- 10 replies

So i have heard stories of people finding crystals in shells on the peace river. I'm assuming it's yellow calcite but i could be wrong. Anyone hear the same or know some places?

I was playing around in the garage tonight and thought to clean up a piece of scaphites that I'd picked up last fall in a ravine leading to the Smoky River in Northern Alberta. Three of us had worked our way down some pretty rough bush and eventually made our way into a mucky draw. The slope above continues to slump and it's not an easy time finding a place to pick around. One of the lumps I found was a crushed piece of shale 'glued' together by calcite crystals and holding a broken piece of scaphites. It's a fragile piece and it wouldn't take much to break it all apart but I carefully exposed

Hi all, I've been searching the internet pretty thoroughly the last few weeks, checking everywhere multiple times a day to find a low-quality keichousaurus to practice prepping on, (knowing that 95% of specimens are fabricated or heavily restored) and I think I may have found one. The price is so reasonable that I really don't care whether or not it's partially fake or restored, as it will make a decent display or even a gift if it turns out to be 100% fabricated. So I suppose I'm wondering how much of this specimen looks fabricated, and if it would even be possible to attempt an air abra

Trip to the Eagle Ford, Kamp Ranch in memory of Joe Gallo, aka Fruitbat
KimTexan posted a topic in Fossil Hunting Trips
This post isn't so much about the fossils, but about me honoring the memory of Joe Gallo. It was the day I went out to do that in my own way and say goodbye and find closure for myself. So, if you're all about the fossils you may want to move on to another post. Two weeks ago Saturday I was on call. I had planned to go poking around at a Pleistocene area I had seen the day before NE of where I lived, but I got called into work to work on a kidney transplant. I worked from 9:30 AM to 3:00 PM. By then it was too late to go to the Pleistocene area since it was over an hour away from w- 20 replies
