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!

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.- 8 replies

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 Missour

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 -

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: Seedles

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

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

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! -
Are these trilobites? Tried to post the 3rd one and can't so far
