  4. Hello and Happy New Year to all of my Fossil Friends! Yesterday and today I put in my first 2 hunts of the year. The weather here has been mild and I almost went fishing instead. But the fossil gods were calling to me and I couldn't resist their siren song. I decided to visit a site that I haven't been to for awhile. I am sorry but a have made a New Years resolution to no longer name locations for the world to see. This is a site that I have gone a few times with minimal results. Mainly it is a rather large site and the rock is hard to work. But I knew the potential for nice finds were there. So, Yesterday I arrived in the afternoon, planning on putting in a few hours. I started off on a lower layer. Now there is multiple layers of shale mixed with slate and limestone. The way this material fractures is rather strange. Which makes recovery of specimens rather tough. So while I found many cool things most where damaged in some way. Crinoids, brachiopods, bivalves, gastropods, nautiloids and trilo Cephalons were fairly common. Some were even pyritized. I must have been there for a couple hours before I decided to explore farther up the slope. I noticed a different color rock closer to the top, but there was really no where to stand. I grabbed a couple loose pieces and started seeing parts of corals and crinoids that were larger then any I have found before. Also partial trilo bits and pieces of Eldregoeps. I looked for a way to get to the very top of the slope and found a way that was not at first obvious. And then bingo! I found a small section that was easier to work and I immediately was rewarded. I started finding abundant amounts of horn coral, large crinoid segments and a nice slab with a horn coral with a trilo right next to it and possibly more. Then I removed a chunk of rock and uncovered a huge tabulate coral about the size of a dinner plate. Unfortunately this specimen was fragile and was broke into a million pieces. But I recovered some of the larger pieces. It started getting dark so I left for home with plants to go back this morning, which I did. Today was much of the same tons of corals but one horn coral was about the size of a grapefruit. This is definitely a different species than I am used to seeing. Most if not all need to be cleaned up and possibly prepped. So I plan on trying to clean up and get the mud off. I will post pics later this evening. It looks like this year has started off with a bang. I hope it is a sign of things to come.
  5. On Friday I made a visit to an Atlanta area gem/mineral/fossil show. Generally I have poor luck at these shows, in large part because there are only a couple of dealers with fossils. This trip was different. One of the dealers was selling some items from an old collection. Most of what I bought was exciting to me because they are species I have wanted for a long time, for one reason or another. First up is a nice (to me at least) New Jersey Tiassic coelocanth, Diplurus newarki (I think the genus might have changed but Diplurus is OK for now). The dealer thought it was just a skull so it was very cheap, as the rock is very black and it was hard to see the skeleton in the room lighting. I used the flashlight on my phone to give oblique light and was very happy at what I saw! He also had some ammonites I was excited to see. Two are Triassic, a Ceratites nodosus and an Acanthoceratites spinosum from Germany. I collected a Ceratites when I was a kid (about 10) living in Germany, but it broke and all I have left is a piece. I've wanted a better specimen for roughly the last 50 years! I started to clean out the inner whorls on the Acanthoceratites but that will take quite a while. There was a third ammonite that was labeled as another Triassic species, but when I got home I recognized that it is actually a Placenticeras, a Late Cretaceous genus. I am not sure of the species and the preservation is different from the North American sites I know about, so I suspect it might be from a European source. I'll post more photos in the Fossil ID thread to see if anyone recognizes it. I also scored a trilobite I've wanted forever, an Elliposocephalus hoffi. Not because it is especially pretty, but because it is representative of the Chechosolakian Cambrian that is so important in trilobite lore. I also grabbed a nice Calymene celebra. Last up for now is an OK shrimp from Lebanon. The body is all authentic, but I'm not 100% sure about the appendages. It's pretty nice though so I like it. There are a few other little things but the above is enough for now. When I got home a box of New Mexico ammonites from the Christmas auction was waiting for me, which made a good day even better!

  6. On Monday I went on a little trip to one of my top secret places to fossil hunt on the shores of Lake Michigan. It's a small beach in Northeastern Cook County, Illinois which I've always found lots of Silurian aged fossils. (1) This trip was no different!! https://silurian-reef.fieldmuseum.org/narrative/392 I found a large amount of small but pretty interesting Silurian fossils which demonstrate the diversity of reef supported aquatic life in the Chicago land area 444 to 419 million year ago during the Silurian era!

  7. This important new paper from Allart Van Viersen and Gerry Kloc @GerryK should cause an indeterminable number of revised labels around the globe! Hollardops mesocristatus (Le Maître, 1952) has been restricted to the holotype from the Chefar el Ahmar Formation, Algeria. "The replacement of the unidentifiable name-bearing type of H. mesocristatus with the poorly preserved paratype of evenly imprecise geographic and stratigraphic provenance would be pointless. Therefore, we prefer to restrict H. mesocristatus to the holotype. This is a rigorous measure but one that enables the objective recognition of distinct species, albeit with the knowledge that one of these might potentially belong to H. mesocristatus when future collections at the type locality are conducted. Still, that would require the near-impossible identification of the specific bank that the holotype was extracted from as well as sufficient specimens to span a range of holaspid instars, in order to validate an unambiguous relationship with the type." This is the revised and updated list of the valid species from Morocco: Hollardops aithassainorum – Chatterton, Fortey, Brett, Gibb & McKellar, 2006 (lower Eifelian, Morocco) Hollardops angustifrons – Van Viersen & Kloc, 2022 (upper Emsian, Morocco) Hollardops boudibensis – Morzadec, 1997 (upper Emsian, Morocco) Hollardops burtandmimiae – (Lieberman & Kloc, 1997)(upper Emsian?, Morocco) Hollardops hyfinkeli (Lieberman & Kloc, 1997) (upper Emsian?, Morocco) Hollardops klugi – Van Viersen & Kloc, 2022 (lower Emsian, Morocco) Hollardops kyriarchos – Van Viersen & Kloc, 2022 (upper Emsian, Morocco) Hollardops luscus – Van Viersen & Kloc, 2022 (upper Emsian, Morocco) Hollardops multatuli – Van Viersen & Kloc, 2022 (upper Emsian, Morocco) Van Viersen, A.P., Kloc, G.J., 2022 Functional Morphology, Coaptation and Palaeoecology of Hollardops (Trilobita, Acastidae), With Descriptions of New Species and Two New Genera from the Devonian of Morocco.

  8. Day Two ; Locality Two (or Seven if you include Day One) Prepping and Retail, Erfoud, Morocco. 20th February 2019 Erfoud town itself is famous for its beautiful fossils, its skilled fossil preppers and also for its wide variety of fakes, composites, good and bad repair jobs and utter frankenfossils. A large percentage of fossils from Morocco that are available in shops and on the internet the world over originate from here or pass through the place. Fossils are sent here for prepping from all over the south and then sent from here everywhere in the country and abroad. There are many little shops, prepping centres with huge attached shops and 'museums which are really pretty much just shops as well. Top Tip :The prices here are about ten times the price of the prices in the little shacks on the edge of town or elsewhere in Morocco, but haggling can reduce the cost significantly. Many places have 'fixed' prices, but they're actually always negotiable. This time, we went to the one my friend Anouar, who is a tour guide, takes his tourists and I was asked politely not to accuse the owners and chap who'd show us around and do the chat, of having fakes or wrong info, so i had to bite my lip. We asked if it was okay to take photos and they said yes, which I was surprised about, but I guess it was because Anouar was going to use photos for his own purposes and this would involve advertising the shop. Top Tip : You will see a lot of fixed prices in Moroccan Dirham in the pieces and shelves. Divide by ten to have a price in US dollars. Because we were with Anouar, we were told everything is 50% of the marked price, but I suspect they often do this anyway, "Special Berber prices, today only". I've heard that before. And you can still haggle to get something way under that 50% and you just know they'll still be making a good profit. I didn't buy anything. Little local stores are more my line anyway - I rarely shop in supermarkets. Here is the entrance where you can see huge plates ready for prepping and polishing, some have been cut into pieces and they glued back together it seems to me, I know this happens with the crinoid beds, so i guess it's true of the orthocerid and goniatite stuff too. Some just look cobbled together because of the circular saw marks when cutting out upper layers.With these, polishing will remove the grid lines. These sheets are from the local area and contain the goniatites and orthoconic nautiloids we were walking on earlier, but from a better quality, less eroded and distorted source. Famennian, Upper Devonian, I think. This photo shows one of the trenches they dig to reach the best quality material, similar to the ones i was walking along earlier this day : Below, somebody walking on the slabs and some maps of the the world at different times in it's past, showing continental drift. : Notice these are not the famous black orthocerid marbles that come from elsewhere. The picture of Spinosaurus is a bit misleading, as you all know, it's not found in these marbles or in the Erfoud area. In fact there is very little Kem Kem material available here these days, though there was in the past. I suspect the Kem Kem area probably has it's own facillities nowadays.

    trilobite species identification

    can anyone help me identify this trilobite? it will soon be mine but it was mislabelled as Morocconites malladoides which it’s certainly isn’t. have been told it might be a Reedops cephalotes
  10. I've recently been looking over the geologic formations in Illinois and I found one that's a bit interesting - it's a Cambrian period outcrop but it seems to be a bit small, only found in parts of Ogle and Lee County, Illinois. http://ebeltz.net/firstfam/1stfam.html https://www.osti.gov/servlets/purl/1202269 https://ilstratwiki.web.illinois.edu/index.php/Cambrian_System I haven't heard of a lot of fossils coming from this area so I'm wondering if anyone's been fossil hunting in that region of Illinois before and how common are Cambrian Fossils from Illinois's Ogle and Lee Counties?
  11. Here is a thread to share some of your rarest partials that if whole would've been incredible specimens, but you know how it is sometimes... Yet they still amazing to own a piece of. I will start off by sharing a piece of the tail of a Probolichas Kristiae, an incredibly unique looking rare lichid trilobite from Oklahoma that would've of been incredible if whole of course yet this piece still has amazing detail and I am more that happy to own

    Trilobite ID

    I was hoping someone could identify these two trilobites. I’ve had them as long as I can remember but I never got them ID’d and I’m terrible with trilobites. I have no information on the time period or the location. If higher quality photos are needed I can take them.
  13. It's been a long while since I've posted on here. I haven't been able to collect much lately, but I recently went out to some new haunts and came back with some pretty intriguing stuff I'll hopefully get to follow up on later. I'll start off with an interesting discovery I've had recently. The outcrop exposes rocks stretching from the upper(?) Brallier Formation to the middle(?) Foreknobs Formation. Although I tried searching in the past for brittle star trace fossils, I was mostly unsuccessful in this regard, and over time my interest in it shifted to the much more fossiliferous beds of the Foreknobs (formerly Chemung) Formation. A couple of years ago I posted about finding a fish bone in a boulder next to the outcrop, as well as pointing out I found some potential teeth. Going over my posts, that finding intrigued me so I dug deeper into the presence (or lack thereof) of fish remains in the upper Devonian strata of the region. What I came up with was an 1887 report of the Genesee Shale from New York, an upper Devonian formation roughly analogous to the Scherr (and possibly the lower Foreknobs by the sound of it, it's all rather ambiguous) in Maryland. The authors noted multiple occurrences of fish bones and isolated teeth in sandstone and "fine pebble conglomerate"...similar in description to the rocks of my own outcrop. Coupled with the knowledge of possible fish remains I found previously I decided it'd be worth it to give the outcrop a more thorough look over, this time concentrating instead on the conglomerate facies and ignoring the shale. What I discovered has so far been fairly interesting. As I stated previously the outcrop exposes parts of the Brallier and Foreknobs Formations, including several dozen feet of shale and siltstone in the Foreknobs grading into upper siltstone and sandstone beds closer to the axis of the syncline. Towards the top of the exposed section of the Foreknobs is a bed several inches thick of hard, pebbly conglomerate. After some searching the silty shale above and below the bed is mostly unfossiliferous, although local profusions in brachiopods, crinoids, and other creatures are present. The conglomerate, however, is densely fossiliferous to the point that it forms a veritable coquina in parts running for several feet along the exposure. Because the conglomerate is so hard (made up of quartzose pebbles and sand), and the underlying and overlying beds made of much softer shale and silty rock, the conglomerate is poorly exposed outside of the exposure wall, forming something of a canopy between it and the less resistant layers. It is covered in part by a dense layer of talus from the overlying beds, likewise obscuring part of the exposure. Luckily, however, a few boulders have eroded out from the cut and are free on the ground to examine, and a few loose pieces weathered from the boulders are present around those. In these rocks I have found one chunk of blueish-white fish bone(?), and several possible tooth fragments. I recently examined the outcrop wall looking for more bone/teeth still present in the outcrop, and discovered part of a fish tooth(?) exposed slightly above one of the boulders, and similar looking black enamel(?) specks that could be fish derivatives. They are distinguished from the quartz pebbles by their shiny black appearance, whereas the quartz is mostly lighter gray and translucent. Is this a possible bone bed in the Foreknobs Formation? More scouting is of course needed, but there's a strong possibility in my opinion that, at the minimum, this conglomerate layer is a decent source of fragmentary Devonian fish remains. Note the blueish tint to the fossil. This possible bone fragment was found in a boulder of quartzose, pebbly conglomerate in the middle-upper Foreknobs Formation (Famennian). Note the associated fauna of crinoid and brachiopod fragments. Crinoid stem fragments in particular are extremely common, comprising a large part of the conglomerate "pebbles." This boulder is derived from a layer above a Cyrtospirifer disjunctus bearing shale, indicating it's Chemung age.
  14. Hi all Just a quick question , I have been very interested in the material from Mazon Creek since I won a great auction lot from Ralph that included a few fine specimens . While looking today online I spotted a trilobite pygidium that was labelled Mazon Creek it looks like the right type of siderite concretions but it could be from some where else . So what do we think? I don’t think they was native to Mazon creek but maybe transported there by floods ?
  15. A few weeks ago I went on a fossil hunting trip to Albany County. I was hunting in the New Scotland formation which is lower Devonian in age. It was very quick and easy to collect in and the dry dredging technique was quite useful. The rock was a very thin shaly limestone which could break easily but many of the fossils had been silicified, making it easy to pop them out of the rock. I found many different species of brachiopods, some gastropods, lots of corals and large bryozoa and a few trilobites

    Madison County meetup

    Hello all! Today I met up with my good friends @Dean Ruocco and @KompsFossilsNMinerals to collect a couple of Hamilton Group sites in Central NY. The first site we went to was the famous Deep Springs Road site, and then we hit a second location for a little while afterwards. All around it was a good day of collecting, with everyone having success in the trilobite department.

    Madison County Trip W/ Forum Friends

    Hi all, yesterday I met up with @Nautiloid and @Dean Ruocco in Madison County to collect some bugs at DSR and another site nearby. After exchanging some gifts we got to work collecting, you can see some of @Nautiloid’s finds on his post here… Dean and I got to work creating benches in a promising area whilst @Nautiloid checked out an area at the site I had mentioned to him prior to the trip. Straight off the bat we were all finding some decent bugs, here were the only Greenops I found yesterday. I always like to collect some of the weirder associated fauna found at DSR, such as these Hyoliths. This one has both a Hyolith and a cephalopod I didn’t find too much Dipleura wise, only a decent head and some single segments, the latter of which I left at the site. After we finished up at DSR, we decided to move onto another site which I was told not to mention, so I will honor that request.

  19. Well took a trip about a week ago ran in to another member of TFF we both did well. I’m holding up on prepping until I get some new bits in. However here is a preview of what I collected think I even scored a whole one time will tell.
  20. I recently stumbled upon this informative gem of an html article discussing modern trilobite lookalikes. Being a trilobite-cephalon myself, I found it fascinating, so I wanted to share it with you all! The article: Trilobite imposters

    Field Collection at St. Leon

    On my eighth trip to the locality, I collected fossils at the famous St. Leon roadcut. Exposed were the Waynesville and Liberty formations, which date to the immense coral reefs of the upper Ordovician, or 450 ±5 MYA. The site was heavily picked, its erosive forces slowed during Indiana's summer heat. My drops of sweat evaporated on the sun-tempered limestone faster than I could count to ten. Despite the setbacks, acquisitions were generous. Best for last. Behold my brachiopods. The top row is Strophomena sp., the top-left sample demonstrating encrusting bryozoan. The second row is Vinlandostrophia ponderosa. The third and fourth rows are Lepidocyclus/Hiscobeccus, though I am of the opinion the genera are synonymous and are just sexual dimorphs given their identical ages, appearances, and regional occurrences. I am curious what other brachiopod enthusiasts think of this similarity. (Four boxes on the grid is 25 millimeters.) I continue with the bivalves. The top row is Caritodens sp, the top-left sample being a particularly well-preserved example. The bottom-left sample is Anomaladonta sp., and the bottom-right sample is a near-perfect Ambonychia sp. Life is incomplete without the gastropods! I didn't take French in high school for nothing! The top sample is unknown to me, despite being the second I have found of its type. The middle-left sample is too buried. The remaining four are all Paupospira sp., the middle sample being a good example. Interestingly, the bottommost Paupospira has a partial Flexicalymene sp. trilobite cephalon on it, which makes me question if the trilobite was consuming the calcium to augment its own development. However, considering the sample is a messy storm deposit, it is likely pure luck. I have to mention the numerous Isotelus maximus fragments at the site. When looking for fossils at St. Leon, one must wonder how many beautiful I. maximus lie under the surface, only to crumble down the slopes of the roadcut and into my hands. Of interest is the long, delicate genal spine on the top right. Now to the more interesting fossils. I follow with three of six total straight-shelled nautiloid cephalopods. The middle sample is a rare, (calcified) Anaspyroceras sp., and the right sample is also calcified. The beautiful, ancient calcite crystals within the dull-appearing right sample: Now to the next three. The left orthocone is all associated and is very large. The middle sample is also quite large. Species-level identification of orthocones can be difficult even with a clear cross-section of the siphuncle, so "straight-shelled nautiloid cephalopod" will have to suffice. However, I suspect these three samples are likely Treptoceras sp. Excellent samples to say the least. I kept saying "straight-shelled," so perhaps some of you guessed it: I found a coiled nautiloid cephalopod! These are very rare. I have found only a handful of these. Behold the curved Beloitoceras sp., a member of Oncocerida, to which the modern nautilus owes its existence to! It's unbelievable how this rock from half a billion years ago directly led to the existence of modern nautiloids! The continuity of life is incredible. The penultimate is a bryozoan fan. Yes, a fan! The bryozoan tapers off at the upper edges. I have never seen anything like it! It is 8x4 cm. And finally... ...a giant bryozoan! This is my biggest single fossil find ever! The caliper on the left is set all the way out to 15.00 cm! It is easily 15 inches in diameter and four inches thick! After crashing my bicycle a few weeks ago, this immense find could be my new wheel! Hear me out. In ten years of collecting, I have found many rare trilobites, behemoth cephalopods, and more, but this colony of tens of thousands of individual animals takes the cake for the most interesting fossil I've ever had the privilege to collect. On top of being huge and complete, it's riddled with trypanites (trace burrows for you bone hunters out there) from all a manner of creatures that used to reside in the Ordovician. I'm sure my fellow amateur paleontologists appreciate that this isn't just a fossil coral, it's an entire ecosystem! It's literally a window into life 450 million years ago! It's riddled with traces left by crinoid stems, scolecodonts (boring worms), parasitic encrusting bryozoans, brachiopods, bivalves, and so much else! I'm considering donating it to a museum. Thank you so much for reading! I hope you enjoyed.

    Fossil Preparation Services?

    Has anyone on here had a good experience with fossil preparation services? I’m not asking for specific companies (as I know this might be a breach of TFF community rules), just wanting to know if anyone has had good results with fossil prep companies in general. I’ve got a couple of nice-ish Devonian trilobite partials in need of prep and am too impatient to prep them myself. Also full air scribe setups are extremely expensive, this isn’t even taking into account that there are no spare rooms in my house for a fossil prep workshop. Meaning, I would either have to build onto the house or build a shed for my prep equipment. I apologize for rambling on a bit here, just wanted to make it clear that I really don’t have any other options.

    Trilobite and shell indentification help NY

    Just started searching for fossils since moving to central New York. These are some finds from Madison County. I was hoping for some help, I know they are trilobites, but not the species. There were also some shells I was curious about. Thanks.
