I'm a newbie to The Fossil Forum. I hike in the hilly areas of south-central Indiana (mainly Morgan, Monroe & Brown counties) whenever I get a chance and many times I end up walking the rocky creek beds looking for fossils & unusual rocks. These creeks are rich in geodes and there is a lot of shale & limestone. I believe that some of the unusual finds are geodized fossils. I have several that I'd like to share with the forum to get opinions from the experts. Attaching multiple photos (15 total: 3 groups of 5) of 4 different specimens with the first five photos showing a pair w

I was in Sylvania OH this weekend and among many other pieces, I found these. I finished prepping them as soon as I could. The first is a pyrite paraspirifer bownockeri.....it is perfect, not a blemish or chip. This one is a paraspirifer (I think) but different. About 2 inches across. Has a few flaws. Then there is another pyrite bownockeri, same size as the first one, nearly perfect but for a chipped "wing" and a hole. But the hole exposes that it is also a geode....containing calcite I believe. I've never seen or heard of a geodized pyri

Hello wonderful fossil-people! If you and you're gang enjoy solving a groovy mystery, I have a post for you! This rock was found in an area of Northern Arizona that is very well know for producing lots and lots of bryozoan, brachiopod, and crinoid fossils, as well as crystals and geodes. The bit of rock in question was found in the side of what appears to be a broken geode. There is a triangular fragment of stone that does not match the material surrounding it. There is also a white discoloration encompassing the triangle that I've highlighted in green on one of the photos below. The colo

I have a rock with a lot of fossils in it - What should I do?
BillRigg posted a topic in Fossil Preparation
Hey all! So I found what appeared to be a large geode, but upon further investigation turned out to have 5 or 6 fossils imprints! They seem to be seashells, scallop-like so possibly bivalves or brachiopods. I'll attach the pre-cleaning pictures below, then some more later after I rinse it and dry it off. My big question is: since this thing definitely has fossils (I can see at least two are half buried in the stone matrix) and is very likely a geode (it's heavy, has dimples, and I can see shiny facets in a few of the dimples), what should be next step be? I wanted to crack it open al -
not a clue on this one, also from the land between the lakes in Indiana or Kentucky, magnet highly attracted, VERY heavy i cut a sample to send in and was a little surprised when saw..this..made me think of the movie, the faculty. lol

Hello. My grandmother found this probably in the 1920’s. I have conflicting information. Some say is dinosaur egg, some say sedimentary geode. I must admit it looks nothing like the other geodes she and i collected together but perhaps it is. Thought i could get your opinions on this. Probably found in central texas although she never said where she got it. Thank you for your help. I can take better photos if these not good enough. Just let me know. There are no crystals inside.

A very odd rock found by my wife in Arizona as a child. Exact locality unknown. Lots of textures. There are some pretty long crystals in the cavities. Could this be a geodized fossil? If so, what kind? It doesn’t really look like pictures of geodized cephalopods or crinoids. Thanks!

I believe these are geodized crinoid. Found at my residence in Casey county, Kentucky. I know crinoid are very common and I believe these could all be. I posted on here a month or two ago and have learned a bit since then but I like extra opinions. Thank you

Hello all I haven't posted in a while. I haven't really been able to get out much for a while, but recently I did find a few (i believe) Composita lying on top the ground just off the road near Albuquerque. Some were complete and some eroded. They seem to be filled with crystals. One in the matrix. I also wanted to show you guys this other fossil in a matrix. A friend was showing me some rocks around her yard when she show me this one. At first I thought it was just a rock with some white inclusions. She liked th

Hi all, I found this in a stream in Eureka, MO, USA. If anyone can help me with identifying, please do!

I have so many rocks that I often like to take one and remove as much matrix as I can, to learn more about it. This rock was very interesting! The limestone was very soft and I know for a fact that I removed plenty of small fossils along the way, but I thought I was digging a geode out of the rock (the "original" thing was the dark area). After cleaning thoroughly with vinegar and a toothbrush, I started removing all soft matrix with a dental pick. I was surprised to "break through" to a totally different geode than the one I thought I was digging out! Part of this new geode broke off late

Found fossil in a stream in Eureka, Missouri, USA. Does anyone know what the fossil may be?

Trilobide geode, bought in Morocco from a street vendor. I tend to assume it's real, because nobody would wish to work on a fake for such little money - but I will accept your expert judgement. Size about 6x4cm. If real, what is it?

Hey all, I’ve found a number of these pretty geodized shells with incredible smoky and clear quartz crystals in the Kansas City area. Have you guys ever found anything like these?

My wife and I recently traveled to Brown County, Indiana (Nashville) so she could attend a friend's baby shower and, while she was there, I slipped away to check out some local streams for fossils. I remembered finding lots of geodes and crinoids around Lake Monroe (to the west) as a kid attending scout camp so I was hoping I might have similar luck on this trip. I lucked out and the stream I checked had many, MANY geodes and a smattering of crinoids and other fossil material. After doing some searching on this forum and elsewhere online, it seems these geodes are frequently formed around (wit

Sometimes, when you go on a fossil hunt, you find more than just fossils. Some friends and I traveled to southeastern Iowa in Spring '18 to scour the Mississippian for fossils, but while there, we noticed that many of the homes that we drove by sported geodes in their front yards. Intrigued, we decided to investigate for ourselves. As it turns out, the area is well-known for its geodes (Iowa's state rock is the geode), so we promptly decided that we had to collect some for ourselves. We eventually found a privately owned piece of property where we could fill a bucket with geodes fo

I found this 'geodized snail' in a 25lb lot of kentucky geodes I got off of online years ago. I'm going to call it a geodized snail till one of you corrects me because thats how the seller referred to it in the post. Again, I haven't really prepped a fossil up to this point but I've gathered some information from this forum! From what I've gathered an airscribe would be a good way to start? Would it be safe to attempt to chisel off the larger chunk of matrix?

This was from my Grandpa’s collection of ocean treasures. I think it is some sort of fossilized coral conglomeration, as I also see what looks like bits of shell. It weighs about two pounds. It also looks like a geode, but I always thought geodes were from the earth, not the sea. Any help you can give me would be appreciated!

My brother found this while hiking I believe around Mammoth Lakes, California. Its almost perfectly round and feels somewhat light so it may be hollow. Google says its a concretion. My mom thinks its a Geode. What do you think?

This is the part I found, I know that I know the outside of this geode or rock or whatever from some thing, but I can’t find it... marine fossils....? Didn’t know if corals could be geodes if it is a coral, by all my posts on here everybody knows I don’t know what I’m doing

Found these all laying around the same area by an old creek flowing from the mountains into the Yukon River, Alaska! it was like a nest of them! Lots of round rocks near this creek as well, then angles bedrock surrounding this creek area...the rounder ones are very heavy! Working on better pictures with a scale, weight, etc for identification.... in the upper left hand corner by the hand, the larger dark rock has 'rib' markings as well as the rock below it...then the small rock in the left upper corner by the hand seems to be fossilized bone or tusk... then the smal

Hello all, I've come across something intriguing. A couple months back I found what looked like a geode. I've only recently got to splitting it, and got more than I bargained for I believe. This popped out of the dead center of the rock. I've given some of the other crystal lined peices to my brother, so I don't have all the peices of the outer. There are some brach bits in the rock, so there are fossil remains forsure. Are my eyes playing pareidolia on me, or does anyone else see what resembles to be a crinoid calyx? I'm happy alone to have the little brachiopodic bits druzied. All opinions a

I found these super cool fossils turned geode today. Any idea what kind of crystals they might be? I was thinking calcite or quartz. Much appreciated. (Edit: Doesn’t react to vinegar, so silica or clear quartz maybe?)

I have about a hundred pounds of what I believe to be fossilized coral and sea plants. Any help would be appreciated.
