Over the Fourth of July weekend, I made my annual pilgrimage to Western NY for a family get-together/reunion. I have been going to the Rushford Lake area for over 20 years now. I usually take a partial day to do some fossil hunting further north and west of that area, closer to Buffalo, NY. This year, as a change of pace from hunting my usually Middle Devonian haunts, I decided to try to get back to a site I went to last year with Jeffrey P that exposes some Silurian aged sediments. I've come across differing opinions on what stratigraphy this site exposes. Some consider this site to be part of the Clinton Group and Lockport Formation, while others consider it to be a Rochester Shale/Lewiston Member exposure. Either way, these fossils are Silurian in age. This is a surface collecting locality, where I get down on hands and knees to search for tiny fossils that have weathered out of the under-laying limestone/shale areas on a hillside. There are chunks of matrix to collect as well, that show hashplates of bryozoans, crinoid, and shell material. I arrived to the site a bit after 8:00 AM. I took my time, and scoured the hillside with a pair of +3.00 reading glasses on, to better see the tiny fossils. It stinks, getting old! This is what the area basically looks like: Rock hammer for scale lower center. As I hunted, I threw interesting looking fossiliferous chunks of matrix down to the bottom of the hill, as I explored the surroundings. I took a few small chunks home to put in the garden to weather out some. I came across a few interesting/photo worthy flora and fauna while hunting. A nice Common Daisy: And a little Yellow caterpillar - possibly a Tiger moth caterpillar: Here he is, on the ground, looking for fossils with me. Note the large amount of ramose bryozoan bits, scattered along the ground. There are also some fenestrate bryozoans, and a Leptaena brachiopod visible in this picture. . I spent about 2 to 2.5 hours at the site, moving along on hands and knees, picking up whatever looked interesting. I found quite a few things. Some corals, both Favosites parasiticus, and Enterolasma caliculus. Ramose and Fenestellid bryozoans. A number of small to miniscule brachiopods - Rhynchonellids, spiriferids, and strophomenids. A few bits of trilobites, both Dalmanites and Flexicalymene. A gastropod, which still needs some prep, and a few crinoid bits. (My identifications come from THIS WEBSITE. ) Here is a group shot of my loose finds. I will have to take some pics this evening or tomorrow of my matrix pieces. I found a really nice, large plate of a crinoid calyx. cystoid! Caryocrinites ornatus. Ruler is in CM. Here are the Trilobites: And a Leptaena with a crinoid (or cystoid?) plate attached, and a tiny brachiopod- unidentified at the moment. More to follow.

This gastropod was found at Jacksboro Texas in the Finis Shale member of the Graham Formation, Late Pennsylvanian. It resembles some of the smaller species of Pseudozygopleura except for the strongly disjunct coiling near the apex. A steinkern can exhibit similar coiling once the shell and columella are gone but not just at one end and you typically wouldn't see the ornamentation at the anterior end. It is 1.5 mm long.

Hello, I was looking throug my fossil storage, when I suddenly found this danish flint nodule with an interesting, spikey looking imprint that I have no idea of what it may be. I have some literature about fossils from the baltic coasts, but nothing shown in it seemed to match. I was wondering about the spikes, and the stem it has, so I thought brachiopod, but nothing matched. Hopefully you guys are able to solve this mystery. Age : maastrichtiam-danium formation : flint, danish flint Finding location : Langeland, Denmark Sice : about two cm long (hole counted in) Sorry, but Im not able to secure good pictures of the stem section, as its only visible when light directly shines into it. So when I hold my camera in front of it, it blockes off the light, and then its only black.

The last 30 days have been great. Not the largest numbers of fossils, but high quality. I went to a highway median lower Eagle Ford exposure in South Grand Prairie, Texas, and another nearby Tarrant formation exposure on 3 occasions in the last few weeks. I have a lot of firsts from these excursions: unknown gastropod absolute unit of an ammonite, a 5.1 pound acanthoceras amphibolum with huge spikes concretion with conlinoceras tarrantense with original shell and septarian veins mosasaur vertebra partial (?) lobster in a pre-broken concretion metiococeras ammonite (rough one but my first) numerous conlinoceras tarrantense ammonites 2-4 inches diameter

Since I’m new here I’d like to show some of my finds from a past trip searching a freshly covered dirt road in Berne, NY, ... and a nearby shale pit that is on the Cotton Hill Coral Bed. The shale road has had trucks brought in from two locations. One being from the shale pit I also explored but the other is unknown. Dr. Bartholomew has helped me identify many of the finds. I found one nice trilobite that I was told is a proetid so I’m happy about that. The gastropod is a Bembexia. Both of these from the unknown location as well as the clams in the upper left and the cephalopod pieces. The large bivalves are Grammysia bisulcata from the Cotton Hill Bed. The round brachiopod is a Lindstomnella from the Cotton Hill Bed. The small Favosites is also from the bed. We found some Favosites in this location that were almost 5 feet across. I have one that we managed to get into the truck that is three foot by three foot. The Cotton Hill Bed is amazing, and loaded with fossils. There are horn corals laying everywhere as well as Favosites. It’s truly awesome to see how filled with life the area was millions of years ago. IMG_5256.dng IMG_5257.dng IMG_5258.dng IMG_5259.dng

Fossil hunting weekend to the Jurassic of Luxembourg (BE & LUX)
ziggycardon posted a topic in Fossil Hunting Trips
Hi everyone, Two months ago our fossil club the BVP (Belgische Vereniging voor Paleontologie) orginized a fossil hunting weekend to the Jurassic of Luxembourg (Both in Belgium & the Grand Duchy of Luxembourg) during the 13th & 14th april 2024. The first day we visited the Socogetra quarry in Sampont, Arlon, Gaume region, Luxembourg, Belgium. The layers in this quarry date back to the early Jurassic, the sinemurian to be exact, around 200 million years ago. While not an extremely rich quarry when it comes to fossils, potential finds are Bivalves like Pinnidae, Greslya, Cercomya and Cardinia. Currenly there was a temporary exposure where some Gastropods were to be found, which were my personal favorite finds in the quarry. Besides that there is a chance to find ammonites (though very rare) as well as sometimes shark teeth (even rarer) and Brittlestars (very rare). The most common finds are crinoïd stems. Day 1: Sampont, Belgium - 13 april 2024 We met in the morning at a forest road which led to the quarry where we met with the quarry owner who told us a bit about the quarry itself. I soon met with my friends Tom & Tineke who I hang out with most during our hunting trips, and we were joined by another girl called Anne who was new in our club but who decided to hang out with us the entire day. While the finds where sparse and not always of great quality we all did go home with some nice gastropods and lots of Crinoïd stems. But most important of all, we had a fun day with great weather and amazing company! Some people were lucky enough to have found some decent ammonites. This was the spot where we started and ended as it seems the best fossils were to be found here. Full of Crinoid stems and if you started sieving the sand you could find the gastropods. We first searched the surface. Lot's of pieces of Crinoïd stems on the sand. After doing some surface hunting we went to a higher level of the quarry. Here we found some bivalves (though not of great quality) as well as some partial ammonites, though other members managed to find complete ones. Partial weathered ammonite block with Bivalves Me & Tineke After finding not really much at the higher level we went back to our original spot but started sieving instead, it was then that we found some of the nicer gastropods. Cardinia sp.

Some Relatively Heart Shaped Fossil Gastropods or Bivalves? In Phosphatic Nodules ( Missouri )
Samurai posted a topic in Fossil ID
Location is in Missouri The area is dated to the Pennsylvanian Formation: Iola limestone formation Subformation: Muncie Creek Shale Member Hello and happy valentines day ! I was re-examining my old collection of Muncie creek shale nodules and found these peculiar specimens Originally I posted an image of one of my larger heart shaped fossils in my member's album, where someone mentioned it could be some sort of bellerophrontid gastropod. But now that I have found a second more complete specimen, I think it was time to ask fossil ID to get more eyes and possible identifications. Specimen #1: My newest specimen and one I found to be heart shaped This specimen also has some weird sphere like structures beneath it so I took more up close images of it For this specimen there are no other parts of this nodule as I found it fragmented. Specimen #2: (2.3cm) My largest one and the one possibly identified as a bellerophrontid gastropod Size comparison between this specimen and the smaller specimen Specimen #3: I think this is just a regular old brachiopod or bivalve but I just wanted a confirmation on such! (The individual is 6mm long) It also died near some fish remains Both halves of the nodule Right side of the nodule -

Mourlonia lucina? Gastropod from DSR I stumbled upon in my weathering pile. Doesn't match the usual Glyptomaria found here so it caught my eye. I'm not too sure on the ID as I couldn't find any images online of similar specimens, so had to go off figures from the field guide.

Hoooooooooooorrrrrrrrrrrraaaaaaayyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here we are at last, into Adam's Silurian. Thanks for looking. First up is the Lower Silurian or Llandovery and I begin with a problem. I posted this one incorrectly in Adam's Ordovician as it had got it's label muddled up with an Ordovician Favosites I had that has vanished in the move here, but is being replaced by kind forum member @Herb Anyway, this, I remember now I've found the correct label, is from the greenish Browgill Formation, part of the Stockdale Group from a cutting near Skelgill (Skelghyll) in Cumbria, Northern England. It seems to be a tabulate coral, but I can't find any listed for this location, only mentions of small, rare, rugose corals. It has the star shaped corallites of a Heliolitidid, but seems to be tightly packed together like a Favositidid. A couple of species of Palaeofavosites seem to be close and are a bit star-shaped,, but anyone know any better? @TqB@piranha hmm who else? The coral bit, an external mold, is a maximum of 3.5 cm across and each corallite up to 2 mm.

Micro heteromorphic silicified ?gastropod ?microconchid Mississippian, England
TqB posted a topic in Fossil ID
Does anyone recognise this tiny silicified shell? It's about 2mm long. I haven't seen one like it before from the Carboniferous. From the Great Limestone (upper Mississippian, Pendleian Stage) from Weardale, Co. Durham, England. From a piece I've been dissolving in acid, containing silicified brachiopods, gastropods etc. It starts off with an open helical spiral (3rd photo) and then straightens out. It also has clear annular ribs. Although the preservation is imperfect and sugary, I'm sure it's shell replacement rather than internal mould, judging from other fossils in the pece. The various serpulid-like gastropods and microconchids I've come across elsewhere don't have the regular ribbing.

Ameura missouriensis Trilobite and Amphiscapha Gastropod
Samurai posted a gallery image in Member Collections
From the album: Missouri Trilobites
Found this beauty on a trip near Nodoway county along the Platte River. This most likely belongs to the Kereford limestone member of the Oread Limestone formation. The limestone itself is oolitic and can be seen in the missing/glabella cast of the trilobite. It sits atop a possibly a very thin to nonexistent layer of the Heumader but definitely atop a larger exposure of Plattsmouth with beautiful brachiopods with spines. This trilobite is definitely a rare find for the area.- 3 comments
