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

A seemingly simple question seems to not have a simple answer. How many orders of trilobites are there? Not everyone agrees on the number but is there a number that is generally accepted by the experts? I have seen anywhere from 9-14 different orders. @piranha has 14 in this thread, Sam Gon III has 11 on his site and I have seen many other sites with different numbers. Which is most up to date? Thanks in advance for any feedback. I'm going to tag two resident trilobite experts ahead of time. @Kane @piranha That was more than one question but they're all in the sa

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

Dive Into an Ordovician Ocean—Trilobites—And a Rare Find
FossilSniper posted a topic in Fossil Hunting Trips
On July 1st, 2021, I went for the first time to a public, personal site and was very pleased with the results of my fossil excursion. The locale consists of several exposed formations, namely the Liberty formation I was hunting in. In my region of southwestern Ohio, that's known to be one of the best fossil-hunting formations due to its remarkable preservation of particularly fragile Ordovician life, even when compared to the excellent fossil preservation quality of other formations in the area. The thirty-three degrees Celsius heat was rather hot by itself, and as the sun's rays- 4 replies

I have had this trilobite since I was a small child, I’m now nearly 35. I don’t know anything about it or it’s value. I am looking for help on identifying what kind, how old, and anything else helpful. Anything helps. Thank you!!

My collection of some really cool fossils on the land most of the fossils I have in my collection are bought so it’s always nice to find something actually in the field. Now my main goal with this post is to try to identify the trilobite I found today although it only has the head piece, it clearly shows the eye and part of the gabella. The horn coral which are the sort of conical fossils should help identify the age of the rocks. if anyone else can give an ID on the rest of the fossils that would help thanks. By the way these were all found in Dane County, Wisconsin. (PS) I have no clue what

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

Hello to everyone. I am studying Geology in the Aristotle University of Thessaloniki and I am facing difficulties in passing the subject of Invertebrate Paleontology. This subject requires Identification of fossils both in power point but also live. Because of this I am interested in buying models (paper models, plastic models , whatever) of fossils. I have been told by my professor that some of the samples exhibited during classes were sold to the University a very long time ago by a well known shop which I will not name that sells such products. Sadly though I have not been able to find wha

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

Trilobite- real or fake?
Science_Teacher_1996 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, I am brand new at fossil collecting and am trying to get specimens for my science class (I’m a high school science teacher). I bought a few fossils pretty cheap not knowing how prevalent fakes are. I think some are fake, partially faked, or enhanced. I don’t want to misinform my students in what is real and what isn’t so I’d love some help! (Fakes aren’t the worst thing for me since we can discuss the use of models in class, I just need to know what is real or fake). Here is my first specimen: a trilobite of unknown origin (I havnt seen one like it online which is why I think it i- 9 replies

Cephalon, or more specifically - a glabella, my father found today, here in Poland. It is an erratic boulder and so its age is likely Ordovician or Silurian. Can someone tell the trilobite group or even a genus?

First trip of the year today to the "Fossil Gardens" at Paulding, Ohio. This is quarry spoil of mid-Devonian age, Silica Formation. There was not a cloud in the sky, and temps were relatively warm at 43 deg. F. I was the only one there for most of the day, and it was extremely peaceful. What a great day. Here are pics of some of the finds. These are "farm fresh" and haven't even been washed yet, but I did take time to polish some horn corals and get some acetate peels (couldn't wait). A large Cystiphylloides rugose coral.

A mollusc Sinuites plus a free cheek of a trilobite. Any thoughts about the trilobite in question? Thanks in advance, Miguel
