Howdy all, Found these in my usual spot in the Drakes formation. The first two look like some sort of bivalve, not a brachiopod. The second looks like some sort of coral.
-
Howdy all, This is something I've wondered for a while. What is the relationship between the Drakes and Kope formation and what are the differences?
-
Howdy all, Been finding some crinoid stems in my usual spot in the Drakes Formation and I'm wanting an ID on them. They look similar to stems from Agaricocrinus americanus from the Carboniferous of the eastern U.S., though they were found in an upper Ordovician deposit. Any ideas?

Howdy all, I've been wondering about this piece for a while. I picked it up thinking it was just a strange rock but someone said it was a worm burrow. What do y'all think? (Found in the Drakes Formation of Louisville, Kentucky).

When it comes to fossils, I am a generalist by nature. I haven't met a fossil that I didn't like! However, in an attempt to narrow my focus a bit, I have decided to take a cue from Adam ( @Tidgy's Dad ) and start this thread. I hope to showcase some of my collection, but more importantly have a central place to post IDed specimens, information I have found regarding them, and/or ask for help with IDs. Hopefully other's will get enjoyment from seeing the specimens and potentially learn a thing or two. So come along on my journey through the Carboniferous! If you haven't had the pleasure of getting lost in the Cambrian, Ordovician, or Silurian with Adam, you are doing yourself a disservice! I highly recommend his below threads. Adam's Ordovician Adam's Silurian Adam's Cambrian Now, let's go! Kentucky is known far and wide by fossil collectors for being within the Cincinnati Arch, and having wonderful Ordovician fossils, but what many fail to realize is that the Ordovician makes up a small percent of Kentucky's exposed strata. By far the most represented time period is the Carboniferous. With Central to Western Kentucky being mostly Mississippian in age, and Eastern Kentucky (and part of Western) being predominantly Pennsylvanian. There is a reason that coal is big business here! A simplified version of Kentucky's geological survey map, but it gives you a good idea of the distribution of what can be found. Image borrowed from: Bryson, Lindsey & Gomez-Gutierrez, I.C. & Hopkins, T.C.. (2012). Development of a new durability index for compacted shale. Engineering Geology. s 139–140. 66–75. 10.1016/j.enggeo.2012.04.011. An adaptation of the KGS map found here https://www.uky.edu/KGS/geoky/index.htm I'm lucky enough to be within an hours drive from most represented time periods. Excluding the Tertiary/Cretaceous and Quaternary, but I live in the Mississippian area and find myself hunting that time period more often than not. The Mississippian here is mostly marine in nature with brachiopods, corals, bryozoans, and the like, being the norm. While the Pennsylvanian is a mixed bag of marine and terrestrial life. More information regarding the geology of Kentucky can be found at the Kentucky Geological Survey website here. I would also recommend the open access papers below regarding the Carboniferous and it's invertebrate fauna. I have not studied terrestrial and vertebrate life much yet, but will showcase those finds and related research material as they come. Mississippian Fauna of Kentucky Pennsylvanian Invertebrate Fauna of Kentucky The fossils will come next, and I plan to post a new one regularly (Daily? Weekly? Monthly?) as time permits. So sit back, grab some popcorn, and enjoy the adventure. Carboniferous here we come!

Howdy all, Found this in my usual spot in the Drakes formation. Looks like some sort of concretion, what do y'all think? Louisville, Kentucky.
-
Howdy all, Found this a little while ago in a Silurian deposit near McNeely Lake park in Louisville, Kentucky. Part of me thinks it's a coral or something like that, but part of me wants it to be a plant fossil of some sort from a younger layer.

9-15-23 to 9-17-23 Southern Indiana and Northern Kentucky Collecting
Nimravis posted a topic in Fossil Hunting Trips
This past weekend I spent the parts of 3 days collecting in Lawrenceburg and St. Leon, Indiana and well as up and down the AA Highway in Kentucky. Here are some random pictures of the sites I collected. Here are some miscellaneous finds- burrows, Trilo-bits, Bryozoan, horn coral, brachiopods, trace fossils, etc. My favorite finds are always hash plates. I love how they show a snap shot in time. Although I mainly collect Mazon Creek fossils, I still like nice hash plates from the Ordovician more, some of them have so much stuff going on. Zoom in on the pictures, they are really cool. Continued on next post-

Found these in a silurian deposit in Louisville, Kentucky. Any idea what they are and if they're fossils or not?

The Cincinnatian Series (Upper Ordovician) is well known for producing beautiful echinoderms. The crinoids and edrioasteroids are probably best known, but some other weird groups do appear locally. This is a slab of Cheirocystis fultonensis, a cystoid that only occurs in a maybe meter-length interval spanning the base of the type Cincinnatian (uppermost Point Pleasant Formation into the Fulton Submember of the Kope Formation). I collected these last winter in northern Kentucky and just got them back from being prepped today. These are some of my favorite echinoderms – they're just so weird! As found in the field. I took this photo while waiting for the ice to thaw so I could safely lift the slab. After prep. They turned out very well!

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 ???? Corals: Widder Formation, SW Ontario Jeffersonville Limestone, S. Indiana Petoskey Limestone, NW lower Michigan Hyolithids: Arkona Formation, SW Ontario Tentaculitids: Arkona Formation, SW Ontario Conulariids: ???? Bryozoans: ???? Brachiopods: Silica Formation, NW Ohio ???? Pelecypods: Arkona Formation, SW Ontario ???? Gastropods: Rogers City Limestone, NE Michigan ???? Non-ammonoid cephalopods: ???? Ammonoid cephalopods: Arkona Formation, SW Ontario Pelecypods: Dundee Limestone, NW Ohio Arkona Formation, SW Ontario Rostroconchs: Dundee Limestone, NW Ohio Trilobites: Silica Formation, NW Ohio Arkona Formation and Widder Formation, SW Ontario Haragan and Bois d'Arc Formations, SE Oklahoma Non-ostracode crustaceans: Chagrin Shale, NE Ohio Arkona Formation and Widder Formation, SW Ontario Silica Formation, NW Ohio Echinoderms: Arkona Formation, SW Ontario Silica Formation, NW Ohio Thunder Bay Limestone, NE Michigan Graptolites: ????

This is a molt fragment of Isotelus sp. that I found in the Drakes formation in one of my usual spots. I've found isotelus pieces before, but this one is odd to me. In particular, I don't know what the lines on it are (not the cracks, I have the lines I'm talking about outlined in the pictures). I thought they might be a possible injury but I'm not sure.

Hi guys! Helping my grandpa clear out his collection, we stumbled across this. It's apparently from the Breathitt Formation somewhere in Kentucky, and we have no idea what it is. Is it some sort of root cast? We found some horsetail and scale tree stuff from there online, but no comparisons to this.

I found these two pieces in the Drakes formation of Louisville, Kentucky a little while ago. I'm 85% sure that these are molt fragments from Isotelus maximus but needed a second opinion. One could argue that these are simply iron coatings on pebbles, but if you look at the second one, the "coating" dips down into the pebble, and is also mixed in with a few other fossils such as vinlandostrophia. Then again I could still be wrong, I have been before.

Brookville, Indiana, St. Leon, Indiana and Wilder, Kentucky Road Trip
Nimravis posted a topic in Fossil Hunting Trips
Yesterday (5-5-23), I decided to take a quick 4 1/2 hour trip (350 miles- one way) down to the tri-state area to collect Ordovician road cut fossils in Indiana, Kentucky and Ohio. Before heading back today I did more collecting and also hit the Geo Fair that was held in Sharonville, Ohio. This post will show the types of fossils that I came across, some I kept, many I left and some will be passed out at the ESCONI Braceville Shaft Mine trip tomorrow. BROOKVILLE, INDIANA- This is a great roadcut to collect, but it is a tall location on 45 degree angle and very easy to loose your footing and slide down. There were a ton of Turkey Vultures flying overhead, here are a few. Vilandistrophia (?) Partial Caritodens Rafinesquina Stromatoporoid- Ambonychia- Ambonychia and Caritodens- Cyclonena- Hebertella- Horn Coral- Other misc pieces-

These pieces of shale were found in a bed of shale in Dykes Quadrangle of Kentucky. The pictures shown depict of a larger piece of shale I had originally found and to preserve. The original shale rock broke into a few pieces, (two of the pieces depicted in attachments). I am able to see some distinguishable areas on the shale that are likely fossilized remains. Do you notice any visible fossils or trace fossils? Do you think the green coloring may be carbon prints from plant life? There appears to be some iron and or sulphur staining and green coloring of parts of broken pieces including one as viewed in attachment. I welcome and would appreciate any assistance given.

Black bits are shiny. Found as float, so no guarantee it's local. Click for larger view

I actually found this several years ago, around the time I started collecting, and always assumed it was a type of Calamites. However, I recently noticed that Cordaites leaves (such as this example) have a very similar appearance. I wouldn't have expected it to have been preserved so... cylindrically though? Roughly 1.5" wide. Thoughts?

Was found while paddle boarding in lake water. Just curious what it could be? Never used this site before but any help would be greatly appreciated. Spherical in shape all the way around. Both horizontal and vertical lines around it but mainly the really close horizontally striped lines all the way down and around the piece

Earlier this month I spent a day collecting in the Kope Formation (Upper Ordovician) of northern Kentucky. It is one of my favorite formations to hunt, and I always walk away with some nice stuff. Here are some of my better finds. A decent Ectenocrinus. It is crushed but should turn out nicely after prep. A much smaller Ectenocrinus hiding in a hash plate A pretty classic Kope hash plate. There's a cluster of crinoid arms to the left of center - I doubt there is a calyx but we'll see. A very nice Cyclonema This was a bucket list find for me: a nice example of a crinoid "log jam". There are two little Cincinnaticrinus calyxes mixed in. My best Cincinnaticrinus to date On the trilobite front, not much luck was had. I had been hoping to find some nice examples of Flexicalymene granulosa but found only some weathered partials. But my last Kope site did end up producing something much better: a partial Acidaspis cincinnatiensis! I've never found anything besides a free cheek of this rare bug, so this was certainly a trip maker.

Hello, I got this cool little Scolecodont (annelid worm jaw) from the Ordovician Fairview Formation of Kentucky. It's tiny as one would expect at 3 mm long. Does anyone know what species it's from? I found a reference for IDing scolecodonts from Cincinnati Ohio: http://drydredgers.org/scolec2.htm, and Nereigenys seems like a decent match with my specimen, though the first two "hooks" are much more prominent on mine. These are also different localities.

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).

I found several remains of an orthoconic nautiloid yesterday while hunting in the Drakes Formation. I was showing it to @FossilNerd and he was unsure if it could be from the Ordovician Drakes Formation, or if I found it where the Drakes overlaps with another younger formation. Is there anyone who knows of such a formation or if this is indeed an Ordovician nautiloid? If it is Ordovician, that would most likely make it Endoceras, as this is the only nautiloid that I have found to have some kind of record in this area. The area in particular of the Drakes Formation is the Bardstown Reef. Here's some websites I frequently use to identify things from the Drakes. https://www.mindat.org/paleo_loc.php?id=19139 https://www.uky.edu/KGS/fossils/fossil-kinds-found-in-ky.php
