Hardly anybody ever talks about the Cambrian fossils of the southern midcontinent (USA). They're super-underappreciated. Show us what you've got! Here's one to start us off: Thorax and pygidium of a trilobite, possibly Orygmaspis, typically referred to as "Orygmaspis cf. Orygmaspis llanoensis" but probably a different species altogether. Note the two pairs of macropleural spines marking the final thoracic segments. Davis Formation (late Cambrian: Furongian), south side of Highway 8, St. François County, Missouri.

Hello! In the past couple months I have been searching out terrestrial arthropod fossils of the carboniferous. In this time I have procured quite a few specimens that I would love to have examined by members of the community, especially those experienced in the identification of carboniferous fauna. I will post the specimens one by one over the next week, if they turn out to be something different than the name they were sold by I will not be disappointed. My experience in Entomology and close disciplines such as Arachnology and Myriapodology has only been with modern species, excluding minor experience with arachnids in amber, so I am so excited to pick your brains! The first fossil was indicated as being from the Carboniferous Zaleskie Beds of Poland, dated at 314 mya. It was sold to me as a "roach" though I know roaches had yet evolve so if so i'm guessing this would be a roachoid. The fossil itself is 3.0 x 2.5 x 1 cm. I will be posting pictures of the specimen below, please let me know if you have any questions or need further information to support a conclusive ID. Thank you all so much for your help! Looking forward to your input.

Paleozoic rock. I found this looking back through some scrap rocks. I think this is a stone I found some crinoids, brachiopods, horn corals, and a trilobite in before. .75 inches long (sorry for not including a scale in the picture) thanks!

Just a note that James Cullison's 1944 monograph on the rocks and fauna of the upper Lower Ordovician of Missouri and Arkansas is now freely available for download or perusal at https://archive.org/details/paper-cullison-1944-the-stratigraphy-of-some-lower-ordovician-formations-of-the This publication has always been devilishly tough to get a hold of. A nice systematic paleontology section deals with the many gastropods and other mollusks as well as the less diverse brachiopods, trilobites, and sponges. The monograph covers the following formations as currently accepted in Missouri: • Smithville Formation • Powell Formation • Cotter Formation • Jefferson City Formation Enjoy and share as you like. Full citation: J. S. Cullison, 1944: "The Stratigraphy Of Some Lower Ordovician Formations Of The Ozark Uplift."

Help requested: Western NY / PA Late Devonian eurypterids & sponges
pefty posted a topic in Fossil Hunting Trips
This Missourian is headed out to the Late Devonian of western New York state and Pennsylvania this coming week and hoping for a little help from y'all on localities for eurypterids and the sponge Hydnoceras. Are Clarke's (1920) Hydnoceras localities at Brown Hill (near Cohocton, NY) and Irish Hill (near Bath, NY) still productive and accessible? Are Ehlers' (1935) eurypterid localities at Bush Hill (near Smethport, PA)? Or are there other spots I should be checking out? I understand that the Trimmers Rock Formation in the vicinity of Bloomsburg, PA, is also worth a look for eurypterids, but I don't have any pinpoints mapped. If you're local to the area and want to show me the way yourself, I'll gladly bring you some Missouri crinoids Thanks in advance . . .- 3 replies

This is a belated report from the Briggs TFF gathering last spring. Here are some photos of TFF'ers working the site: Here are my finds (not in phylogenetic order). Scale in mm throughout. I guess I'll start with one of my bucket listers, a large goniatite: Next, the trilobotes: And "those other arthropods": Now the gastropods: Other Mollusca: Crinoidea: Seedless vascular plant bits: I don't usually collect "hash plates" but such accumulations don't seem very common at these sites, so I picked up this nice one.

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 commonly observe the item of interest; paler orange indicates times in earth history to less commonly observe the item of interest. White indicates very little to no practical probability of observing the item of interest. Please keep in mind that the listed indicators are things like “conspicuous horn corals,” purposefully declining to address rare encounters with groups of low preservation potential, low recognizability, etc. Got additions/amendments, especially for the groups mentioned above? Toss them in the comments below! Thank you..... https://docs.google.com/spreadsheets/d/1tVm_u6v573V4NACrdebb_1OsBEAz60dS1m4pCTckgyA

In the years of fossil hunting some fossils caught me by surprise especially the ones out of rough pieces that had no resemblance to nodules . These are some of my less common finds myriapods,arachnids, arthropleura tergite,shrimp carpace and the nymph idoptilus sp. I also found fish scales and flora though not as abundant as Mazon creek . Cheers John

From the album: ocean stuff
Here was a nice surprise. I picked up this fossil cluster of barnacles and noticed a nice layer of agate underneath! When I processed the photo I took of it I saw that the light from my flash dispersed giving this rainbow effect. It's very small but now when I hold to the light I can see the little rainbows!-
