Found this in a Pennsylvanian-era formation. This is my first fossil hunt ever, so I don't even know if a lot of what I found are fossils or not. But this one was the most interesting. Found in some shale in a road cut near Jellico, TN. To me it looks like some type of millipede, or maybe some type of root system. Not too sure!

Hello, thank you in advance for any help identifying. I found these on the cherokee lake bed in Northeast Tennessee Hawkins county they are extremely hard and after washing don't change in appearance. Are they fossils?

A nice Dictyonema flabelliforme dendroid graptolite from Oslo Fields in Norway. It's Tremadoc, Lower Ordovician in age and is thus maybe around 480 mya. Another angle :

The thread http://www.thefossilforum.com/index.php?/topic/84678-adams-silurian/ was getting rather enormous, so I have decided to leave that one to deal with the Llandovery and Wenlock and put my specimens from the Late / Upper Silurian here, though I don't have a great deal of material from the Ludlow and Pridoli yet. However, I do still have some jolly nice specimens to show off here. Here are my other collection threads for the Cambrian and Ordovician ; http://www.thefossilforum.com/index.php?/topic/78887-adams-cambrian/&tab=comments#comment-832018 and : http://www.thefossilforum.com/index.php?/topic/78974-adams-ordovician/&tab=comments#comment-832912 In the mid 1980's, on the way home from one of my annual visits to the Hay-on-Wye second-hand bookshops, I managed to persuade my girlfriend at the time to take a bit of a detour and stop off at a roadcuttting just outside Aymestrey,, Herefordshire in the Welsh Borderlands. The rock here is the Aymestry (sic) Limestone Formation, part of the Upper Bringewood Beds and is Gorstian, Lower Ludlow in age, so about 426 mya and a little younger than the Much Wenlock Shale Formation. Many species of coral, trilobites and brachiopods found in the formation are the same as those found at Dudley, but the bed is noted for its massive numbers of the brachiopod Kirkidium knighti (was K. knightii),a lovely, large pentamerid. In fact, during my hour or so searching, I found almost nothing but this species, the only exception being a couple of Atrypa reticularis. The problem was that this limestone is thick and seriously hard, even the broken bits are generally huge, but I managed to obtain half a dozen reasonable specimens and about the same number of fragments. Over the years I have traded, given away or sold them, so that now I only have the best one left. Here is Kirkidium knighti : It's a shame the tip of the beak is broken off : I make index cards for all my fossils, this is the one I made for the specimens at the time, back in the mid 1980's : And today's version : There was a minor extinction between the Wenlock and the Ludlow, known as the Mulde event and it is often said to have primarily effected graptolites and conodonts, but it seems to me it had a massive impact on the bryozoan faunas of the time too. Gone are the varied stony stick and mound trepostomes that made up such an integral part of many faunas from the Middle Ordovician through to the Middle Silurian and even cystoporid groups such as the Constellariidae became extinct at this time. Trepostomes and cystoporids did survive until the end of the Triassic, but were never as important again, the bryozoan faunas would start to become dominated by fenestrids in the Devonian, though they reached their peak of diversity and distribution in the Carboniferous. I will look closely at my limited number of rocks, but I don't think I have a single Late Silurian bryozoan. I know our friend @Mainefossils studies the Late Silurian Leighton Formation in microscopic detail, but I can't recall him posting any bryozoans. Are there any, Asher, old chap? Interesting.

The Devonian period is known as "The Age of Fish", but could also be known as "The Age of Brachiopods." In the Early / Lower Devonian, brachiopods reached the height of their diversity towards its end in the Emsian. We see the ancestral groups occurring, lingulids, craniids, orthids, protorthids, pentamerids, rhynchonellids and strophomenids, as well as the later successful groups we have seen before such as atrypids, athyrids and orthotetids, plus the rise of spiriferids, spiriferinids and productids and the beginning of the terebratulids. By the end of the Devonian , several of these groups are extinct or severely reduced in importance and brachiopods never quite recover. Also, the Devonian is the last time we see trilobites with such variation, large sizes and numbers and orthocerids too are much more uncommon after the rise of the goniatites. The massive tabulate coral reefs also disappear after the Devonian. Fascinating period and I hope to share some of its wonders with you. Equally, a lot of this is rather new to me, so I would be very grateful for any assistance, corrections or further information on my specimens. Thank you. The Early Devonian epoch is split into three stages, so let's start with the first of those, the Lochkovian, that began about 419 mya and finished roughly 411 mya. I have been sent a nice selection of brachiopods from the Kalkberg Formation, Helderberg Group by the Mighty @Misha, mostly. But the kind gentleperson also sent me this fascinating little bryozoan hash : It is dominated by fenestellids, which is usually the case in the Devonian, but other orders sill occur. These ones, I think, are Fenestella, but there are so many species in the formation that I wont take a guess as to species : Not sure what this one is ;

Hello, everyone! I am a 34 year old married female that loves everything about rocks, fossils, and gemstones! My husband and I have an extensive collection of all varieties of just anything we thought looked neat or different. My husband recently started working on a house his mom bought and under it is a root cellar with a rock "wall" that I've been allowed to dig in .. y'all, I can't wait to show my finds off. I am certain (although I'm definitely also not sure 😃) that we have stumbled upon something amazing! Hint* dinos and gold/silver!

I found this in Tennessee in a "rock wall" in a root cellar about 3 days ago. The house was built in the 20s but the cellar wasn't dug until the 60s. If that helps at all. And it sits right beside a creek.

Help! So we found this in our backyard and we’re pretty sure it’s a fossil. Any help identifying what it could be ? Found in Middle Tennessee, Dekalb County Husband did the “lick test” he found online and it is sticky 🤣

Need help to ID potential fossils found in The Little Harpeth River in Brentwood, TN
KWalla posted a topic in Fossil ID
I think these are fossils but need someone to verify and possibly identify. I found these in a creek bed along the Little Harpeth River in Brentwood, TN. They were all within a 30’ area in the creek bed. Some may not even be fossils but figured I’d post pictures just in case they were. I’ve taken close ups of the first row and if I need to take some of the other rows I can. “A” and “B” are the ones I’m most curious about because to me they look like actual fossils. ”C”-“E” feel like a shell of some sort, like a turtle. “G” & “H” are cylindrical looking and sound like porcelain when you tap them against something. “T” looks like a finger and has ripples in the sides and is fairly heavy. Not light like a regular fossil would be. “U” almost feels and sounds like porcelain and I found it in the same area as these others. The last one is what I think is a turtle shell that doesn’t look to be a fossil but I’ll leave that up to you all to decide. -
The locality of this fossil was 5 minutes from the Ross Formation in Tennessee. My professors believe that this is a trilobite that has undergone replacement. Specifically the Shepard's Hook Trilobite.

Hello, I have a few specimens my kids and I have found and need help identifying, if they are indeed fossils. I included a dime for size reference, but will try to include a measurement also for each: The first two images are a swirl shape in rock (I was hoping it was a shell) about 4 centimeters across The next images are of two round things (1.5 and 2 cm across) embedded in a rock, there are crinoid stems embedded near them All were found in Hamilton county Tennessee. Thank you for any info

I have a find from a dry creekbed in Apison, Tennessee (Hamilton county). It appears like little segments of columns but doesn't look like the crinoid fossils from the area. The segments are 1-2 centimeters long but some (if connected would be 6-7+ centimeters).

Hello, I found this in a dry creekbed where I have found crinoid stem fossils, and initially thought this might be two stacked crinoid segments or a brachiopod imprint. I thought it slightly resembles a trilobite. What does this look like to you? Found in a creekbed in Apison, Tennessee (Hamilton county).

Help me name the outstanding fossil deposits of the midcontinent Devonian
pefty posted a topic in Questions & Answers
Crowdsourcing / help request! I'm putting together a review article for the fossil collector community on the Devonian rocks of the American midcontinent, which I've defined as the gray area on the map below plus southwest Ontario. I'm hoping to include a section in which I highlight the midcontinent fossils of greatest renown for each of a number of taxa (list below). (I purposely leave "renown" as a somewhat squishy quality open to multiple interpretations.) I would appreciate (1) your nominations of any midcontinent Devonian fossils of great renown that I have failed to capture in the list below and (2) your assistance in filling in the blanks marked with "????" Thank you! List is below. Microbes: ???? Marine algae: ???? Sponges: Formosa Reef Limestone, SW Ontario Rockport Quarry Limestone, NE Michigan ????

Hello from middle TN, looking for fellow hunters!
darkskykosmos posted a topic in Member Introductions
Hello, I have had a profile for a while but never used it. I am sorta new to fossil hunting (a little over a year into it so far) and I recently moved to Pulaski, TN and have spent quite some time looking at all the roadcuts in the area. If you have recently driven on 64, you may have seen me parked at all the roadcuts looking at the rocks and fossils! I am curious to learn more and meet anyone in the area who has spots they know about. I have quite a few on 64 and in the area around Pulaski mapped out and am continuing to explore the area. I have found all sorts of bivalves species, crinoid pieces, gastropods, cephalopods, one trilobite head, worm tubes, tabulate and horn coral, etc. I also have a couple of digital microscopes and am trying my hand in hunting microfossils in soil samples from different areas of the world. I'm usually available weekends if you're in the area, I know there's more fossils and new locations out there! I also work in Huntsville so if you know anything in between Huntsville and Pulaski I could check out I'd love to know. I did notice east of Huntsville has some big roadcuts too, but haven't had a chance to investigate since then. It was raining pretty hard the day I saw them. I'm also in the VBAS in Huntsville if anyone on here is a member. It's the astronomical league chapter in Huntsville, my other passion is learning astrophotography. Chris- 9 replies

This one had a complicated life. It appears to be metamorphic with quartz veins. Wrapped around it are leaves that resemble cat tail leaves or some sort of water plant. . I first thought they were dried or baked on the core rock. No these Leaves are not being scraped off the core rock. They are rock. Limestone leaves that appear to wrap around a core metamorphic rock that somehow fell into perhap a bog or marsh. Was it buried in a peat or some sort of bog ? I’m just baffled. The area where it was found is Watts Bar Lake near Nashville Tennessee. That corner of the lake was at one time dynamited. So it is not like adjacent rock walls. There was more than one. I was sure I could scrape the leaves off but they have become rock. Looking forward to your thoughts on this.

Rock is 7 inches long. Little balls the size of black peppercorns. Was able to remove a ball with a nail. Look the same from all angles. Reminded me of frog eggs. No other shapes.

I’ve been clearing out invasive vines from my neighborhood park/green space and came across these structures absolutely covered in fortunes spindle and green briar. I could see a little part poking out and wow I just had to uncover them. Could they be stromatolites? Or just layered ole weathered limestone boulders? My Google searches of stromatolites did turn up a few that resembled these structures. But only a few:) any thoughts are greatly welcomed!

Woo-hoo! Here goes my first one! I never knew taking photos of tiny, inanimate objects would be so hard!! These are awful and I'm not pleased. I will get better ones if I need to, but I'm curious to see if this is an easy one and no further photos are needed. Ok so these were found roughly a year apart (early 2000s) in the same creek in north-central Tennessee. Not a clue as to the layers or geology. They feel sand-stony, the larger one is rougher. The larger one also has a glob of matrix on (what I'm calling) the bottom with tiny crinoid segments stuck in it. I've been searching online for over a month to find something similar, initially thought crinoid parts, because of the crinoid-looking center in the small one, but I don't find any tri-radial crinoids, only 5-radial (however you say that, haha). The closest I can find to its shape is a pollen spore... oh my, imagine the size of the bees!

Hey folks, this is my second post attempting to identify a potential fossil. The last time members confirmed I had found a 350 million year old horn, coral fossil. Thrilling!potential fossil #2 is a very interesting looking rock. I recently picked up in Sequatchie Valley Tennessee. The more I looked at it the more I started to see a potential mandible, fossil or possibly teeth. Please review the pictures and let me know what you think probably seen one two mini PBS documentaries. Lol

Hello, I hope someone here can identify what I found. I found this rock along the Little TN River and Tellico Lake last winter. This rock has what appears to me as a quarter size piece of coral. thanks
