I spotted this broken ammonite with Crystal's forming inside... I haven't seen this before does anyone know what the crystals could be.... Thanks....

I am wondering if anybody else has ever come across a fossilized Seabiscuit that is showing some form of crystallization

I found this rock in my old collection. I have no idea where it is from, all I know is that the crystals are red, very shiny and glittery, and very small.

TOTALLY GAGA, wow, I don’t care if it doesn’t have fossils- I AM IN LOVE! Tons of blingy wow. Photos don’t do it justice. As that great orator, Pee-wee Herman, said, “If you like it so much, why don’t you marry it?”

THIS ONE HAS SEXY FOSSILS- heck, I can even feel the cockles clamming-up over this one! Sooooo... did I get this right? (Not volcanic glass, and definitely from “ancient water”....right?). :-D

A while ago I bought this tiny gault clay ammonite preserved in pyrite and in a few months of storage next to dessicant mineral these strange white crystals have grown. -pyrite disease?

All the beauty you see against the blue sky is a story of time from the book of rocks, uplifting, cleaving, and eroding in wonderful ways. I searched and got this Socorro County geologic map. A rather immense amount of study involved in this document. Best at 175% zoom. If I lived there all the time I might come to understand it. https://geoinfo.nmt.edu/publications/openfile/downloads/200-299/238/ofr_238.pdf

Hello to all, I am new to south western Utah, looking forward to getting advice and learning about the ancient life here. Are there any good collecting sites for trilobites and maybe fish fossils here in the southwest part of the state?

Nice to meet everyone. I hail from MS and travel all over the US. My hobby is to dig and surface collect fossils, gems, crystals, rocks, etc.

I have been here at the forums for quite sometime now ( I think since I found my first fossils on a trip to Missouri close to 20 years ago?!) Work and life has been very busy and had prevented me from anything more than online hunting, you tube video's, and the lack of actual sites close to where I currently live. (Currently I live above the San Joaquin Valley, in a small mountain community named North Fork. I have had wonderful years here hunting arrow heads and various rocks and minerals, Have found many crystals at the old gold mine sites which are numerous over in Mariposa county next to me, and have had a great time up here! However, I took a trip to Missouri many moons ago to help a family member relocate out here to Nevada, which is when the unexpected happened. When we went to rent the moving truck to begin loading, my mom went inside to handle the rental, and as per my "norm" I took off walking across an open fields with, eyes to the ground,, towards the back of the lot and behind the row of trucks parked ready for rent, towards the railroad tracks. I was finding different minerals and such and then by chance I kicked over a plain down rudy clay looking rock, when I noticed it had a pattern to it. I looked closer and it was a plant fossil ! I was ecstatic, and thrilled does not even begin to cover it. I found several more all of different varieties when I began to notice what the 'commonalities' were with the ones I was finding. From that point on I was hooked! I made several trips back there just for the rock hunting and had found many wonderful 'treasures' which I cherished. I then began to explore more of Missouri to see what else there was to find in this state, and lets put it this way, the first thing on my bucket list is to return to Missouri!!! It got even better, after having my eyes opened so to speak as when we left there we headed to a ranch to spend the night that was owned by family back there. They have an 80 acre ranch. When we got there and I stepped out of the truck, I looked down and could NOT believe my eyes. There were fossils just laying around and exposed all up and down the dirt road which lead from the highway and into the 80 acres. I hunted for the rest of that evening and found more treasures. I have never forgotten that trip, and like I said I plan on gong back there one day before I die, and attempt to find more of those little treasures which made so darned happy so many years ago....and the family back there still owns the ranch too! I have since retired due to disability (heart) and find I have more time available than money naturally, so I am here to begin exploring what is available or close by where I live now, and also any near Fernley NV.. where I spend several months at at time there helping my Mom. I have small amounts of silver in quartz rock, (no gold yet though) many heads, awesome crystals, but my real desire is to find more fossils! So if anyone has any information or recommendations for me I would love to know about them! I am aware of the fossils found down in the Valley at the old landfill dump site in Madera, (wooly mammoth bones, sabre tooth tiger etc.) and I have heard of a dry creek bed somewhere down around the town of Dos Palos and of course Shark Hill and the Ernst Quarries and Ant Hill which is now closed. However its a vast area there, with miles and miles of open high desert area, which leads me to hope that those are not the ONLY areas where one can hunt for sharks teeth and other sea life fossils. Here's to hope! and forgive my long winded introduction but I am happy to be here once again and I'm looking forward to getting to know other members here. Thank you! Debra

Hi there! My name is Karah , I am from Southern California. I found this forum while searching for information about raptor eggs. I am hoping to find out some information on them, which I will post soon. I have recently gained an interest in fossils, I collect mostly coins and crystals. However some of my crystals are formed on fossils such as stromatolite. I am excited to be part of the forum and learn more about fossils!

Are these crystal in the rough?

Zdravo again! Here are some again, interesting rocks that i have found yesterday at Juhor Mountain (Central Serbia). Any thoughts? Maybe a Jasper or something?

Zdravo! I found yesterday few interesting rocks on the Juhor Mountain.I think that they are some types of minerals but i'm not sure cause i'm not so good in to that.Please help Thanks!

Hello from Cyprus, warm wishes for exciting finds to everyone! Here is a relatively bigger oyster than my usual finds, this one is complete and inside small crystals have formed, could be calcite not sure. Took advantage of the heavy rainfall and found it on muddy collapsing hills north of akrotiri area. I found half, and half a meter further I dug out the other half Perhaps you can better see the small crystals that formed all over inside both parts below Nearby I found also the following: found position, but i think they are not matching and this single one

Recently found this odd looking rock with a very concrete like feel to it. it has multiple fossils and crystals on it but what is weird is this flower shaped crystal on it.

I went exploring today. I hit 3 places. The 1st two were the Ozan in Rowlett. The first 2 were a busts, but the 3rd was in the Eagle Ford in Dallas and it was a very interesting place. I can’t say that I found specific fossils per se, but I did find the product/remains of prehistoric animals. I was ecstatic with my finds. Septarian nodules have been on my bucket list of things to find. I found a hill full of them!!! I got there less than an hour before sundown and was thrilled with what I found. This one is very cool, but I’m not sure what the original creature actually was. The only thing I can think of is that it was an ammonite and maybe the septa became crystal filled, but that is a total guess. The curves on the edge and sides don’t look right, but I’m not sure exactly how these formed in the particular area. It honestly looked like the badlands or something desolate with nothing growing there and was a very fine soft gray shale. I found a lot of what I think are aragonite crystals at the site as well as some other beautiful crystals. I have never found any crystals in this form before. So I’m thrilled and hope to go back tomorrow if I don’t get paged into work tonight. This is the one I’m very curious about. Maybe some of you may have seen something like this before, but I have not. I think it is super cool though. I’m pretty sure it was once a critter of some sort. I believe it is a septarian nodule, but there are no septarian marks externally like you usually see. When I was washing off other nodules I found, as I was washing, the exterior began to slough off and the septarian lines became visible. There are basically 7 bundles of crystals across this thing. Some are kind of merged. #1 This one has me most curious of all. #2 other edge. Right edge is encrusted with what I guess could be considered pyrite disease, rusty material mixed with crystals encrusting it. I have found an ammonite before that was rusty with crystals like this. #3 Close up of the encrustation with small crystals jutting out. They’re hard to see. #4 one side. The other side is less descript. The curve on this doesn’t look ammonite to me. I found some pieces that looked almost turtle like, but I don’t know turtle stuff when I see it. I will say the rock material is soft and is a fine shale like texture and material so when wet it becomes slick almost like soap, but no bubbles. This is a 2nd find in the same area. In the center below the crystal on top is a sea shell. Wish I knew what kind, but not much is exposed. All you can see is the mother of pearl inside the shell. #5 note crystal branching in 3 directions below shell, there is also a beautifully formed crystal on top that is pristine and wafer thin that was part of the septarian, but the non-crystalline material has eroded away leaving the flower petal like crystal. #6 This is it from another side. You can see more of the septarian sections. If anyone knows the critter this arose from or the crystal type I’d like to know it. Calcite and gypsum are most common here. There is brown too. I also found stone with green crystals. This is a 3rd find in the same area. #7 I found these bars just laying on the ground like this. They looked so peculiar. I couldn’t figure out what they were. I thought they looked a little like columnar basalt, but knew that wasn’t it. There was a small nodule in the ground less than a foot away that was cracked all over and filled with crystal. I wanted to dig it out. In the process of digging it out I found another hard object just under where these were. I thought it was a solid rock, but when I started to move it the rock came apart in these shapes. #7 cleaned up a little at home. #8 one up close. I believe they are all covered in aragonite or brown crystals. I’ve been told that when an ammonite is encased in a nodule and then the mineralization process takes place that often aragonite crystals form as a result from the nacre in the ammonite shell. I have not found the source of that claim though. Can anyone tell me how these formed and what the crystal is? Is it aragonite? How would I know? I can provide higher resolution pics upon request. I had to make these low res to get all of them in here. @Uncle Siphuncle, @Fruitbat and @BobWill you 3 have hunted the Dallas and North Texas area for many years. I assume you’ve seen these sorts of things and may have insight you can share.

Can anyone I.D? Covered in tiny crystals, looks like a thousand camera flashes going off when you walk by it. I found all these the other day. The big sparklee one is 40 lbs

Hi all!! So I will say that although I love love love fossils (especially ammonites), minerals and crystals are definitely my element (ha ha). So I figured I would share some of my extensive collection. These are more favourites or ones that are special to me! 1. Creedite 2. Stalactite slices 3. Cobaltoan calcite 4. Rutile quartz 5. Apophyllite 6. Blue kyanite 7. Spirit quartz 1. Malachite 2. Botryoidal chalcedony 3. Peridot on basalt 4. Desert rose 5. Dogtooth calcite 6. Pyromorphite

Found by a friend in a creek near KC, Kansas. Never seen anything like this. Also, I'm new to all of this so I don't have the slightest clue what I'm looking at... Is it even real????

Hi, I am just wondering if you could tell me what you think this is? Kind regards Jack

the inside of these have crystals, i think it looks like a clam but i dont know. anyone have an idea? thanks! its 28 inches in diameter.

I collected these from 2 different spots. One from the creek between my apartments. And the other from crystal canyon.

Last fall a buddy and I attended the annual Geodefest in Hamilton Illinois. Its a 3 day festival to collect and crack open the famous Keokuk geodes. The organizers hold half day hunts at various private and public locations to collect geodes. I have gone for 3 years now and its always a great time. And I always come home with buckets of geodes, big and small. My buddy and I had been talking about setting up a time to go through and crack our geodes but never found the time. Well last weekend I pulled out my soil pipe cutter and rigged it for a night of cracking! I loaded my truck with my buckets of rocks and my cutter and met over at my buddy's house. We spent 5 hours cracking over 4 five gallon buckets of geodes. His daughter also joined in the fun of the cracking! You never know what you are going to find in these rocks which is the fun. Here's highlights of the night. Enjoy!
