My first attempt at identification. I hope the pic sizes are ok. I found this in South Dakota. It was my first attempt at finding fossils. Either at the Mount Moriah Cemetery in Deadwood or Badlands. A local expert said it was a shell, possibly ammonite. I'm hoping for a verification. These pics are front and back. ALSO, it feels quite solid but it does have cracks. I was planning to have it made into maybe a necklace for a friend, possibly in a macrame setting. I'd like to make it more solid first. I'd like opinions for how to do this. I've read many ways and products but the opinions are widely varied. Thank you for your time. I have two more fossils and will put those in their own posts. Thanks, Jeff

Purisima Formation (3-7 Ma), Santa Cruz, CA: One piece doesn’t match the rest
Slow_BS posted a topic in Fossil ID
Hi there, I have a collection of Santa Cruz, CA shell hash, from the Purisima Formation. It’s pretty much all non-mineralized mollusks, I think. I received a new piece that seems to be from the same formation (it was a gift from the heir of the original collector who lived in Monterey - the other side of the bay from the formation). The fossiliferous pieces inside this one have a totally different structure - much more of a radial/flakey look. I circled it in red in the first picture, and it’s the only rock in pics 3-6. I’d love to here if anyone has any thoughts on whether the new piece is Purisima, and what the white portions may have been. Thanks for reading!- 14 replies

Hello all, and thanks for being here! I am looking for an ID on these fossils for my own gratification! My focus is in archaeology, so I come across fossils often during surface collection adventures! A little about the location: These were found in Nancy, Kentucky, USA on a partially man made flood-control lake called Lake Cumberland (Cumberland river basin/Cumberland plateau). The banks are rich with small to medium chert concretions, fossiliferous sedimentary stones, and small to medium iron inclusions. Preservation of these specimens are, generally, fair to good. I found this piece along with horn corals, only a couple of brachiopods, and a wealth of crinoid stem pieces in less than 20 minutes! I thank you all in advance for any information you can give me! -Skelly B. Specimen 1- Specimen 2 - Specimen 3 -

I think the curved part of this rock is probably just a coincidence, but since I have never seen anything like it before, I thought I would check. Like a lot of other rocks I find, it seems to have a layer of limestone fenestellan bryozoan fossils encrusted around it (that's about the only way I know to describe it) and lots of tiny impression fossils on the inside of the rock. Can anyone help me figure out the rock's story? What might have caused the curved and layered appearance? Is that just a coincidence? Or is this a particular "thing"? Found in Madison County, Alabama. I will post more photos in follow up comments. Thanks! Ramona

I am learning to pick apart the items I find in the limestone fossiliferous rocks from my yard, but I see some things here that I am not familiar with. What is the tubular item at the bottom of the photo? And what are the tiny round black things? They look like poop, LOL! One of them is inside of a crinoid fossil, but it may have fallen there? This was found in Madison County, Alabama. I find fossiliferous limestone mostly with fenestellan bryzoan fossils, crinoids, coral, etc. Thanks! Ramona

Can anyone identify any of the fossils in this rock? We found it on the beach of Lake Michigan in Benton Harbor, Michigan, USA. Unfortunately, we didn't have any kind of ruler or other measuring device.

My grandson and I found this chunk of fossiliferous limestone in our yard today and I cleaned it with vinegar, but it is very crumbly. I can tell that it contains mostly fenestellan bryzoa and crinoids, which is what we find most of in our yard. What is the best way to preserve this fossil to keep it from crumbling? I am hesitant to clean it anymore due to the fragility of it! Thanks! Ramona

I've got to stop picking up rocks when I take the dog out... I already have so many in the house that I need to clean and study more, but I went and did it again today. It looked interesting, but now I am baffled. I cleaned this just a little bit with a weak vinegar solution and then looked at it. I am used to seeing fenestellan bryozoan, so these little round things caught me off guard. Are they branches of the bryozoan fossils? I I do seem some fenestellan bryozoan elsewhere on the rock, I think, but these little things look like eggs or snails? Point me in a direction and I will go research - again?! Thanks so much for being patient with me and my neverending questions! Ramona

I think I have completed my first full cleaning of a fossiliferous limestone rock. I will post a series of macro photos of the rock here and would welcome input. I am new at this (like I said, it is my FIRST full cleaning) so would appreciate input and suggestions. I first soaked the rock in a vinegar and water solution for a couple of days, taking it out every once in a while and brushing it with a soft bristled paint brush. I had ordered some essence of vinegar to have a stronger acid, so when that arrived I used a very small amount of it on the brush to continue cleaning the rock. I then placed it in a baking soda and water solution overnight, again brushing and rinsing it every once in a while. It seemed to have stop bubbling this morning, so I declared it "done", but would like thoughts on whether it looks completely cleaned or not. I mostly see fenestella bryozoan fossils in it, in different stages and at different angles, so please let me know what else, if anything, you see in this rock. The size of the rock is as follows: 5cm long, 3 cm wide, 2.5 cm tall and I found it in our yard in Huntsville, Alabama. I am posting a number of macro photographs of different areas of the rock and I may ask questions on some of them. Thanks for any and all input!

This is my first post in the Fossil ID section - I am SO excited to find this resource! A have found a few very helpful folks in other places, but this group is a huge wealth of information! A bit of background - we moved into a house just outside of the city limits of Huntsville, AL, a couple of months ago. After finding a couple of fossils laying around in the yard, I decided to investigate the wooded area at the back of our property a bit more. Whoa!!! There is a creek bed on the property and the closer you walk to the creek the more rocks you have to walk over. Every single rock I picked up had some kind of fossil in it. The sides of the creek have rocks embedded in them, too. It seems like someone may have looked around a bit in the past (found a small pile of rocks) but many (MANY) of these rocks are in their natural state. Most of them, in fact. It seems overwhelming to me, but I have been delving into understanding the treasures I am finding. I don't understand all of the classification systems, but I found a place online that seems to indicate that we are in the Mississipian Age? The rocks which have been identified so far are all limestone, so I am assuming this one is limestone as well. The soil is VERY red (someone called it ochre red?) and some of it always remains on the rocks after I clean them. The fossils that have been identified so far are fenestella, bryzoan, crinoid. And I think the word fossiliferous was also used? I am a photographer by trade and macro photography is my FAVORITE, so I will post plenty of photos. This particular rock is a very small one compared to most of them. It is also harder than the other ones I have worked with - less "crumbly". The first couple of photos are of the top and the bottom of the rock, to get a general idea of the size and shape of it. The rest of the images are close ups of various areas. Any and all input is appreciated! Is it common to find an area like this where rocks such as this one are very abundant? From what I can tell these are all common fossils, but a great springboard for learning! Hints on how to clean and store the rocks appreciated, too, since there are so very many of them? Thanks!!

Hi all, I recently found a sedimentary rock that looks like it has small skeletal fragments. The fragments are very small and circular. I first thought it was a fossiliferous limestone that had calcite filled into the shells but it does not fizz with HCl. I have never heard of a fossiliferous silicic rock but that seems to be what it is. Looking through a hand lense I can see small clear to white crystals that look to have a poor cleavage and a fairly high hardness (possibly quartz?). there is also a larger white mineral that looks like it has a radial growth texture, it also looks like it is filling in larger cavities (possibly some zeolite?). The sample was found in a boulder field in the foothills of the cascades in oregon outside of sweethome. There was lots of siltstone in the area. Can anyone help me ID this rock or just tell me some more about it?
