A friend uncovered this oddball today in the Late Ordovician (Sandbian) of eastern Missouri, in the uppermost part of the Plattin Group (a Platteville equivalent) or possibly the lowermost part of the Decorah Group. He's been finding a lot of weird fossils in that zone, including articulated cyclocystoids, but this one I'm at a loss on. Too wobbly for an orthoconic cephalopod, too much space between calcite elements for a crinoid column. Given the size, is machaeridian a possibility? What other ideas should we be considering?

Hi I've been gifted a plate with different ammonites in it. As it comes from a second hand store, there's no record for provenance,age and all other infos. I'd appreciate any help with the identification. Thanks Back of plate:

Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to com- 5 replies

Hello, I am a new user and I recently picked up this ammonite fossil at a local rock & fossil shop. I got it for $80, and it has not been worked on much, only one side has been mostly cleared of rock. I have tried to use various sources on the internet and galleries, but I am new to this and have not been able to identify this fossil myself. It is decently large, and about 8-9 inches across at its longest. There are lots of deep ridges in the shell, but each ridge as far as I can tell is uniform, with no protrusions. Unfortunately, I do not know the origin of this fossil, or the type of ro

I was seven miles south of Glendive; Montana on October 12, 2018; time 1400; exploring a drainage cut into the Pierre Shale Formation while looking for concretions. This scaphites was partly exposed on the surface of a concretion. Later, I removed most of the surrounding matrix.

Not quite sure what is going on here. In my class we were handed a box of fossils and this was in it. My theory is that its the body of a nautilus. Let me know what your thoughts are.

as usual with this publication,very well illustrated account a continuation of the ongoing effort(the results of which are mostly published in the same publication)to understand molluscan taphonomy. Grade on the Doush qualitymeter**: 10(out of ten) those of you who abhor principal component analysis and boxplots: you are hereby warned beforehand.Open at your own peril A word of caution:as with most neontological studies,it begs the question of how all of that would translate to the deeper time fossil record. It might possibly increase recognition of condensed se
