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.

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 th -
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 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

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

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 re

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 th

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 pi

Uncertain if this is from Ocean City or Tel Aviv (minor difference!)... life has been a bit chaotic, and sadly some of my rocks were moved from where they were well organized. (House cleaning to make room so my returning, adult children can have “their rooms back”... jeepers!) Avoiding humans for 5 minutes last night, I noticed three interesting rocks I have not shared before. (I will refer to this as #1 of the 3). Very small but fascinating to me, with both a clear fossil and a clear, smaller imprint, immediately next to the fossil. There are numerous possible oth

Leaping Lizards, is this Fossiliferous Limestone, or am I delusional... (wait, please don't answer)

Wow... so I am learning too much stuff. This is a very dangerously addictive website. One more... a stab at an accurate id.... (ID = identification, not intentionally Freudian despite more than an occasional slip?) -
Another piece from the rock canyon anticline. Both are approximately inch. I find many of these and didn't know if they are worth further investigation or even if they are identifiable, but I have seen amazing diagnosis and seemingly valueless things have scientific value. After seeing the amount of effort and the amount of scientific information continually being amassed I thought it would be worth asking.

Is there a good source for bulk fossil material from different locations around the world?

Looking to trade limestone for shale.
joshuajbelanger posted a topic in Member Fossil Trades Bulletin Board
Hey, looking to trade Ocala limestone, very fossiliferous with calcite inverts for any type of fossiliferous shale. We can discuss amounts later. Will also send you pics and let you choose your specimens. Or I will trade bone valley fossils for the shale. Have peace river and mined fossils, so colors and types vary. Thanks! -J
