My preschooler found this on a hike in western pa. We scoured our Audobon and cannot figure out what it is a fossil of, if it is one at all. I am afraid to ruin it by cleaning it. UV reactive, fluoresces bright yellow-green. Thanks to all you brilliant folks for your help!

I picked this up thinking it looked vaguely like a fish scale, but I'm not entirely sure either way. Collected from the Cuyahoga Formation (Mississippian) in northern Ohio. Any thoughts?

Mississippian mystery ?shell, UK. SOLVED: Isogramma, an unusual brachiopod
TqB posted a topic in Fossil ID
I have seven specimens of these, all with the same appearance and strange internal structure. They have perplexed me for years though I'm familiar with most fossils from the area. (I originally had three and have recently collected four more which enables them to be characterised more reliably. Altogether, five individuals are fairly complete). One small exposure of marine shale, Mississippian, Brigantian Stage, northern England, Co. Durham. The main features are: 1) See photos 3 & 4 -The shell material is strange, being irregularly honeycombed, resulting in a granular a- 63 replies

Hey all I was out collecting in Vienna, Illinois yesterday and amongst what I found was this which looks like vertebrae. The thing is it looks to me to be a fossil but I'm not sure. It's about 3/8 th inch diameter. The area is Mississippian in age. Please can someone help, is this a modern critter vertebrae or indeed fossil. It was laying with a bunch of crinoid stems

I've had the opportunity to collect in some Mississipian-aged units in Georgia recently. Like neighboring Alabama and Tennessee, Georgia's Mississippian is made up mostly of non-clastic rocks, chiefly limestone and chert, with a few notable exceptions such as the Floyd Shale and Hartselle Sandstone. Although other states might be better known for their Mississippian fauna, Georgia boasts many of the same fossils, and can be a good source for them if you can find the right exposure. So far, I've collected in a few different formations in Georgia; the Fort Payne Chert, the Floyd Sha

No idea what this fossil is. Found in Northwest Arkansas, where, I believe, it is part of the Boone Formation, Mississippian Period. I’ve checked my fossil ID book, and every scallop-shaped fossil I see has vertical ridges, rather than horizontal. The fossil is just under 2 inches wide (5.08 cm) and one inch tall (2.54 cm). At its deepest point, it has a depth of 1/2 an inch (1.27 cm). It has a deep ridge in the center and a circular spot at its deepest point (seen most clearly in the second to last photo). Thanks for your help! Addendum: Just discov

Found this in the rocks used to repair our road. Larger and narrower than any of the brachiopods I've found so far. Is it even a brachiopod at all? I assume the rock originated in the same formation as what I've found around the railroad tracks and in my driveway gravel, which I've been told came from the Slade Formation (Mississippian).

Found this guy in crumbly shaley stuff, Monroe County, Indiana. The rippling shape reminds me a lot of a modern oyster shell. Closest thing I can match online is platyceras, but I don’t see any like this. The large associated crinoid plates are about 1/2” diameter for size reference. Is this worth prepping out and trying to glue together/consolidate?

Questions about any large and currently unnamed Ctenacanthiformes sharks known
Joseph Fossil posted a topic in Questions & Answers
As I have been researching large ctenacanthiform sharks from North America, I've been wondering if there are any known globally that are currently unnamed. I definitely know of the large Ctenacanthiformes Saivodus stratus (found in both what is now North America and Great Britain), the large Ctenacanthiform from the Permian Kaibab formation in Arizona, and the 'Texas supershark' (a likely large species of Gilkmanius) from the Pennsylvanian Texas Graham formation (all three as larger or larger than an adult Great White Shark (Carcharodon carcharias)). But are there any large ctenac -
Formation: Bangor Limestone Age: Mississippian Found this location in a remote area of Alabama recently. I Haven't hunted the Bangor in awhile, so I gave it a shot. A fragmentary calyx. Northern Alabama seems to be teeming with these, as I found 8 others in a nearby locality as well. A complete, but squashed roller of a Kaskia? Fenestrella are found commonly articulated with their fans here. This was the best individual I found. My guess is these are Spyroceras? All of my nautiloids come from the Ordovicia

Hey everyone, I've been trying to plan a little trip for me and my family to go on a little fossil hunt. I live in Bartlesville Oklahoma and I have several nice places I can go to find fossils all over. Mainly mississippian and Pennsylvanian. I'm looking for areas within an hour or so drive from where I live. I'm aware of the pliestocene finds in the arkansas river in tulsa area. I'd love for someone to send me maps or geologic surveys showing what areas in the topography, and other recomendations. Places I've been to worth noting: Kaw Lake spillway, Ponca City (good shells everyw

Cracked this open and found an interesting pattern. Is this evidence of a fossil within this limestone? If so what could it be? See the thin strands alongside the main “stem”. Why is the outer layer this color? Some pictures have had the contrast and saturation adjusted to aid with identification I’ve only been searching for and studying fossils and rocks for not even a year. Teach me all the things! The fossils that I’m familiar with in this area aren’t matching up. found near Beaman Park - north west Davidson County, Tennessee. This area has features of th

I found this strange fossil near Sand Springs on the Arkansas River of Northeast Oklahoma back in 2013 or so. I was told by multiple sources that it appears to be a chunk of seabed. Is this from the Devonian/Mississippian period? Can anyone ID any of the fossils on this piece? Any help would be greatly appreciated! Thanks! I have a few other specimens I would love to identify as well! :)) ~Noah Benzing

Tips for Fossil hunting in the St. Louis Area of Missouri
Joseph Fossil posted a topic in General Fossil Discussion
Recently, I've been thinking about conducting an exploratory fossil hunting trip in the St. Louis area of Missouri. I've never been there before, but I've heard there is a lot of caves and limestone outcrops near the city. I've also heard there is a decent amount of Ordovician and Mississippian fossils in the area. I'm just wondering if anyone's been fossil hunting in the St. Louis area before and what fossils can be found there? -
Is Cladodus part of Cladoselachiformes or Ctenacanthiformes
Joseph Fossil posted a topic in Questions & Answers
As I was recently doing some research on the prehistoric shark genus Cladodus, I came across some info that classifies the genus as a member of the family Cladoselachidae, Order Cladoselachiformes. https://en.wikipedia.org/wiki/Cladoselachidae This is somewhat confusing to me as mindat and the Paleontological Database aka fossilworks list Cladodus as a member of the family Ctenacanthidae, Order Ctenacanthiformes. https://www.mindat.org/taxon-8657177.html http://www.fossilworks.org/cgi-bin/bridge.pl?a=taxonInfo&taxon_no=104838 -
Back in June, I posted this Burlington crinoid, wondering if it was worth prepping out. Responses were fairly cool except to say it may be worth a bit of exploration to see. @Ptychodus04 volunteered to give me a hand. He was instructed to put about an hour of work into it and then return the crinoid to me. His resulting exposure left me with the nagging question of do I go further. It was not worth professional prepping, so all summer and fall it sat on my desk begging to receive some attention. This week, I grabbed the specimen and kept whittling away at the matrix u

Saivodus striatus and the Graham formation Gilkmanius: Which one was bigger?
Joseph Fossil posted a topic in Questions & Answers
The Ctenacanthiformes are an impressive group of prehistoric sharks, emerging in the Devonian period before surviving the two Devonian extinction events that gave rise to the Carboniferous. During the Carboniferous, the Ctenacanthiformes diversified rapidly, even becoming some of the Carboniferous Oceans Apex Predators. But of all the members of this impressive (yet almost unknown to the general public) group, two species stand out as especially impressive and awe inspiring - Saivodus striatus and the Graham formation Gilkmanius (this species currently doesn't have a name yet).

The impact of the Serpukhovian extinction on Ctenacanthiform diversity

Help identifying locations of Mississippian era formations in Northern Illinois
Joseph Fossil posted a topic in Questions & Answers
I've recently been trying to locate some new fossil sites (particularly those of Mississippian age) to go to and I found some places that might seem interesting. I found them looking at a slightly old geologic map of Illinois and I was wondering if anyone can tell me where exactly these locations are and if they are particularly fossil rich? https://www.mindat.org/loc-14607.html -
Help request: feedback on layout for blastoid identification guide
pefty posted a topic in Fossil ID
Hey all, I could use some specific feedback on this visual guide I'm working on for the diverse blastoid fauna of the Burlington Formation (Mississippian, Mississippi Valley / Illinois Basin). The job of these 3 pages is to show, on each page, one of the three standard views for all Burlington species. Specifically I'd like to ask whether you prefer the horizontal layouts or the vertical ones. For some reasons I prefer vertical, while for other reasons I prefer horizontal. What do you think? Please keep in mind that these are not the only pages in the complete visual guide -- most- 3 replies

I’ve been going through the finds from my recent(ish) outing with fellow TFF member @Jeffrey P and remembered that I promised Jeff to post this little bivalve. To my knowledge it’s the first inflated and relatively complete bivalve that he or I have found at one of our favorite hunting spots. Any previously suspected bivalve has been fragmented or deflated and damaged beyond definitive identification. It is from the Glen Dean Limestone formation of the Leitchfeild Kentucky area which is Carboniferous (Mississippian) in age. It’s tiny, but was one of the top finds of the d

Hi Everyone, Last month I took a trip from New York to Elizabethtown, Kentucky to attend my parents' 70th anniversary. My sister and her husband, two of her adult children, and my parents, both in their 90s have all resettled there. I try to visit them at least once per year, but my parents' 70th wedding anniversary could not be missed. It is a very long trip from the suburbs of New York City to E-Town and a stop along the way was the sensible thing to do, so I spent the night in Harrison, Ohio near the border with Indiana and only 15 minutes from St. Leon, the well known Ordovician roadc
