3 weeks, 3 days ago3 weeks, 3 days agoWhat you have are sea shell fossils. Even the bits that look like teeth. If you can find out the age of the rock you, it will be easier to identify the shells.

3 weeks, 3 days ago3 weeks, 3 days agoFossilized cracked mud.Abe I would post pictures of such mud cracks that are from cambrian rock formations, but the comments section doesn’t allow for pictures posting as comments. Such mud cracks are a geologic feature left by water features such as ponds, lakes and seas.

3 weeks, 3 days ago3 weeks, 3 days agoAmy Wu the fossils you posted are productid brachiopods. If you can learn the age of the rocks you will be able to narrow down what kind of productid it is. Also try to learned what kind of brachiopods are common for the location of the rock. Some only show up in narrow time span.

Mollusc Mania 2 months, 3 weeks ago2 months, 3 weeks ago2 months, 3 weeks agoCollected yesterday from Kevin member of Marias Formation, near Loma Montana. I have been exploring a strata of sandy shale that is about 10 to 12 CM and is about 6 feet from the top of the Kevin rocks. Above the Kevin shale is glacial till. The explored strata rest on about 8 feet of dark grey bentonite shale. The lower bed of shale is nearly…[Read more]

What is it? 3 months, 2 weeks ago3 months, 2 weeks ago3 months, 2 weeks agoI have plate of brachiopods crinoids stem bits and bryozoans. Next a large piece of bryozoan is a bit of something I don’t recognize. It has what looks like a base for attaching to a stem and cup shaped body. No patterns or signs of attachment points on rim. There are two of these on this plate. Can someone identify these.Note brachiopods ha…[Read more]

Probably the base of a crinoid cup, though not sure if I’m looking at the right thing

David Powers replied to the topic What kind of productida brachiopod is this? in the forum What Is It? 1 year, 1 month ago
1 year, 1 month ago1 year, 1 month agoThere is a strata that contains productids. It rest on a bed of mixed bryozoans. The shale is about 15 feet thick. It rest on a breccia limestone Bed. The breccia is evaporate crusts that were pilled by tidal activity.
In these shale I found part of a plant fossil. I am hoping to find more. So far I have not seen any fish. There are clams a…[Read more]

1 year, 1 month ago1 year, 1 month agoHi James,
Your formation is older. It would be equivalent to the Lodgepole formation which is part of the Madison group in Montana. I also have some Productids from that formation too.
The examples of Echinoconchus I saw were from Kansas coming from Penn age rocks.
The productids in the original post are from the Kibbey formation which is…[Read more]
