  1. Some more Jurassic Brachiopods.

    Hello everyone, I got a few brachiopods from a trade with @will stevenson , I don't have much info on them other than that they used to be part of a Victorian collection and are from Wiltshire, as well as them being Jurassic. Very curious as to what they are, any info is appreciated. Brach 1: Brach 2: Brach 3, Very similar to 2: Brach 4:
  2. Unknown brachiopod

    Hello everyone today I acquired this fossil from @will stevenson and am not sure what kind of brach it is. It looks really interesting and I believe it may be Jurassic, but that's just a guess. Any info would be greatly appreciated. Thank you.
  3. I just made my third trip to northern New Mexico in pursuit of Pennsylvanian fossils. I love this area and I’m especially interested in the Carboniferous periods, and I usually hit a new location on each trip in addition to my favorite location, San Diego canyon near Jemez Springs. But I am always eager to find new locations to hunt! I visited two locations on this trip. I will post my finds from this trip and follow up with another report from previous visits. 1) I spent a few hours at Fossil Hill near Taos. I had little information to work from at this site and had only a little success, but enjoyed the hiking nonetheless. I walked up and down the hill for a few hours, only finding one area with a significant quantity of larger crinoid stems. I also found a single brachiopod and a single Gastropoda. The longest crinoid stem in the image is 1.5” long. This location was near the top of the hill. The fossils were all loose in dirt. I could not find the source layer unfortunately. If you have any good experience at fossil hill, please message me!
  4. Hi, a few days ago I went on my first ever fossil hunting trip to Eben-Emael, a Limestone quarry in Belgium that dates to the Maastrichtian and is part from the type location (the historical ENCI quarry being only a 3,5 km to the north. The trip was orginized by the BVP (Belgische Vereniging voor Paleontologie) and a short report of the trip with phot's and some of the finds can be found in this topic by @Manticocerasman who I was lucky enough to tag along with, cause I doubt I would have found many mention worthy fossils without the guidance of Kevin. But since I am into microfossils I decided to collect some samples of the limestone without the obvious fossils home to later be able to look for microfossils as it should be quite rich. I think I have around 1 - 3 kg of matrix left to look for microfossils. But I have never myself dissolved matrix, and although it seems easy, I don't want to make any mistakes. During the trip they advised me on two different approaches, depending on what kind of fossils I wanted to find. One approach was dissolving in water and the other in vinegar, but now the seeming obvious question. How exactly do I do that? Should I just take a bucket of a glass, fill it halfway with said liquids and just wait? Or should I use a sieve and lay the block there so only fossils remain in the sieve and the rest goes to the buttom. Does the limestone just dissolve or does some kind of putty residu where the microfossils will be in? If so, how to properly remove the fossils when you pour out the liquids without pouring out the fossils? I know I have many questions and some might be very obvious and straigh-forward, but I really haven't done this before and I would like to do it the right way from start. So thanks in advance for any tips & tricks, I would really appreciate any help!
  5. Hey, all! I have a surplus of Upper Ordovician (Cincinnattian series) and Silurian fossils from the Dayton area. Fossils include diverse brachiopods, horn corals, orthoconic nautiloids, and bryozoans as well as trilobite fragments. Would anyone like to trade for these fossils? If there's anything in particular that you'd like from the area that I don't already have in my collection, then I may be able to go search for it before the trade, too. If anyone expresses interest, then I'll upload images of said fossils in the next few days. Let me know!
  6. Monday was an extremely nice one weather wise. I took advantage and visited a small private quarry near Morrisville in Central New York. I've been to this site several times in the past, but the last trip was roughly a year ago. The quarry exposes the Mottville Member of the Middle Devonian Oatkacreek Formation. It is part of the Marcellus Shale which represents the bottom of the Hamilton Group. In terms of fauna it has similarities with the nearby Deep Springs Road and Briggs Road quarry sites which are younger in age. There are also notable differences.
  7. There is a bit of Georgian Bay formation in my neighbourhood. It is littered with trace fossils and guarded by swarms of mosquitos. This area surrenders its treasures very reluctantly. There are a few little bryozoan pieces and not much else that I can see. The exception is a single outcrop from which I've pulled some sedimentary rock and found shell imprints. Some are quite wonderful, and there are several species. I think they might have these genus names: Ambonychia, Rafinesquina, Zygospira. The rocks also have all kinds of "colonies" in them, but I cannot identify them and they are not easy to make out.
  8. Hi all! Now that I'm finally getting around to organizing my fossils into cabinets, I'm looking to get a bit more information on some of them. As I'm currently finishing up the Ordovician shelves of my cabinets, I was hoping to get some help with identifying brachiopods from the St. Leon roadcut in Indiana that I acquired through winning some past auctions benefiting the forum. Photo #1: Mainly strophomenids, I think - does anyone have a more precise ID? Photo #2: Dalmanellids perhaps? Any specific IDs out there? Photo #3: These are really tiny and adorable More to come...
  9. I've bought fossils, and I've found them myself! Here are some of my greatest finds in my collection!
  10. Penn Dixie this weekend

    This weekend we're taking a long weekend up to the Niagara Falls NY area. We're going to be doing the typical tourist stops plus a visit to Penn Dixie. . Based on the weather forecast I would assume to be there at opening time to avoid the afternoon heat and possibility of thunderstorms. I don't know yet if we're going to be there on Saturday or Sunday. Is there any tips or suggestions for first timers to Penn Dixie? We have a rock hammer, mason's hammer, an engineer hammer and several cold chisels. Also on a totally unrelated note any restaurants in the Buffalo/Niagara Falls area that anyone would recommend for the family. Thanks for any information and I will post a field report early next week.
  11. It was a planned family get together at my sister's ranch in Kentucky to celebrate my father's 90th birthday. I was travelling from Southeastern New York by car. Made it to Harrison, Ohio the first day, right on the border with Indiana. Next morning, weather was pleasant and I was out to the famous St. Leon road cut, a place that I've wanted to visit for years. Finally made it there. Spent the entire day. Despite the site's fame, didn't see another collector and except for one brief shower the weather was perfect though a little on the warm side. I explored the entire exposure though the best was just below one of the terraces where the brachiopods and corals were weathering out of the shale complete.
  12. So I went back to Tannery Park to find fragments...got a few gastropods. But walking on the rocks, I encountered lots that I had missed. Brought my wife along and her eyes are sharp. She found a couple of nautiloids so large that I can't believe I missed them before. I'd not noticed many brachiopods before, but I did this time. Also lots of "periwinkle beds". This place will open to the public as a lakeside promenade in September.

  15. A week ago today, I took the day off work to hit one of my favorite sites, a roadcut above the Illinois River in Oglesby, Illinois. This cut exposes the Pennsylvanian LaSalle Limestone member of the Bond Formation and produces abundant brachiopods as well as occasional other fauna including gastropods, cephalopods, coral, trilobites, and shark teeth. The weather was perfect, sunny but not too warm, when I pulled up. The cut is a somewhat unstable slope of cobbles and boulders of varying size, almost all with at least some fossils in them. To get up to the slope, you have to hop across a small ditch with running water. I have a good sampling of the common brachiopods from here, so I am looking for unusual fossils when I go now. I was very happy to quickly find a piece of trilobite as I started to search the rocks at the base of the hill. (I will put pics of everything I brought home in a response post) One interesting find that I was not able to bring home was this Linoproductus brachiopod with some shell preserved and a really pretty dendritic pattern on it- it was very delicate and firmly embedded in the middle of an ~80 lb boulder. I was able to stay for 4 hours, and I felt like I gave most of the site at least a quick look. I am very happy with what I found- I was able to check off many of the rarer things I was looking for, including shark teeth, a trilobite, cephalopod material, and a brachiopod with spines attached, as well as some nice crystallized brachiopods. I will post all of my finds below.
  16. Today I was out collecting in Lawrenceburg, Indiana for several hours, accompanying me was some rainfall. This will be a picture heavy post and I will show various fossils that I found and many pieces that I left in the field. I will start out with trilobite parts of Flexicalymene and Isotelus. I did find my first ever complete trilobite, at least I think it is my first, and also my largest piece of an Isotelus that I have ever found. Now the pieces- Next post will be Bryozoan-
  17. This collecting trip was more of a scouting expedition than an actual dig. After the snow and ice have melted, its fun to get out and see whats newly exposed/uncovered. Today we found the usual cast of characters like horn corals, tabulate corals, brachiopods, gastropods, pelecypods, and trilobites. I was mad at myself for not having faith in a trilobite fossil that I found on this trip. It was barely visible in the rock I found it in and I thought it would be incomplete just on how it looked. I started to remove the matrix (hard limey shale) with a hammer and small chisel. The bug popped out of the rock complete and fell on the floor. The trilobite landed on its glabella and some of its shell broke off. I think I found all the pieces but I should have been more careful. After all these years of collecting I should know better. I promised myself to make up for it and that I would find a killer bug this season with some new sites that I have lined up Thanks and Happy Collecting mikeymig
  18. Sorry I haven’t been around the forum as much for a couple months now but I’m starting to get some more free time recently. Here’s a quick trip @Earth Chemistry and I did a little bit ago. Let’s start out with what stratigraphy we’re looking at here. I’ve been visiting multiple locations of what is locally known as the Gardison Limestone. Source: http://utahgeology.com/utah-stratigraphic-columns/?var=strat_27 It is from the early Mississippian or Early Carboniferous for our international members.
  19. English Brachiopod Identification

    Hello, I just got a surprise package from my Aunt and Uncle who live in Somerset, England. It contained a nice amount of Brachiopods they found near them, at a place called Hill Farm. (May be meaningless to some, not for others.) I know definitively that these came out of the Blue Lias. What they are i'm not so certain. May anyone ID? First Batch: (All look similar; I included back and front sides as well) Second Batch: (Similar to some MD oysters Thanks!
  20. Last Saturday (April 6th, 2019) my wife and I made our second trip to Tully, NY to search for trilobite fossils. Unfortunately this was the second time I was unable to find a complete trilobite; I'll keep searching for them in other locations. I did find some other fossils that I thought were interesting enough to keep. The first photo is of the hill in Tully that I searched. On our first trip I tried to cover the entire hill while we were there, on our second trip I concentrated on smaller areas and had better results with finding fossils. A gastropod fossil which is next to another fossil that is round, flat and has a spiral pattern that is difficult to see in the photo. I found many brachiopods and some bivalves. This is the longest crinoid stem that I've found so far at Tully, it is about 13/4 inches in length. I'm guessing this is another crinoid stem. It has a much larger diameter than the other crinoid stems that I've found and it has "spikes". And two very small pieces of fossil from trilobites, which I was happy to find even though they are not complete. Thanks for looking.
  21. Fossil hunting in the Ardennes

    Hello All Today and the next five days I'm on a family trip in the Ardennes. I am close to the region around Hotton. This is known for the many invertebrate fossils that can be found here. I went to a quarry first. I had to get permission from the owners but they gave if I didn't break the obvious rules of fossilhunting in an active quarry. The weather was very nice and the fossils numerous. What else does a fossilhunter want? I searched in an the loose rocks and didn't even had to use my hammer. The ground here is littered with fossil corals. In 5 minutes I found about 20 pieces. I have no Idea of the species yet.
  22. Chonetid impressions in slate (“Chonetenschiefer”) from the Plabutsch-formation, Palaeozoic of Graz, Styria, Austria (Devonian – Eifelian) The classic occurrence at Gaisbergsattel, west of Graz The Eifelian Plabutsch-formation – mostly fossiliferous limestones – of the Palaeozoic of Graz, Styria, Austria, contains locally beds of slates of various colors. Some of these beds contain abundant limonitic imprints of brachiopods and bivalves (“Chonetenschiefer”). The locality first mentioned in the literature (1871) is that at Gaisbergsattel west of Graz: Austrian map with "classic" occurrence of “Chonetenschiefer” at Gaisbergsattel (red x). Part of geological map of Kuntschnig (1937) with “Chonetenschiefer” between the two red x east of Gaisbergsattel. Here, the slate layer is up to 2 m thick, grey like mice and splits easily in flat pieces (Hanselmayer, 1957). The fauna was first listed in Heritsch (1935): Chonetes subquadrata Chonetes sarcinulata Chonetes oblonga Chonetes nova species (most abundant!) Spirifer aculeatus Pterinea fasciculata Pterinea cf. bifida Pterinea cf. costata More than 10 years ago, my first attempt looking for these rocks was not successful. A few days ago (03/29/2019), however, I stumbled over this rock by pure serendipity. A small piece of it was lying on a rather busy hiking trail (“Mariazeller Weg 06”) east of Gaisbergsattel. Relief map with my first find of “Chonetenschiefer” at the hiking trail (red x) and supposed outcrop area of this rock after the geologic map of Kuntschnig (1937). Hiking trail “Mariazeller Weg 06”, where I found my first specimen. Pic from 04/01/2019. I was able to split the rock with my fingernail – and there they were, the limonitic brachiopod imprints! A faint radial ripping is visible. No other specimen was found on the trail. Now I looked closely at the geologic map, the text of Hanselmayer (1957), and the relief map and decided to explore the area around the red line (see above), where the outcrop of this rock is supposed to be. It’s a forested area with dense undergrowth, among the undergrowth many spiky blackberry bushes… No outcrop was found, but fallen trees have exposed some rock fragments: Abundant limestones, light brownish slates and, yes, some grey slate, mostly small pieces. I split only the largest of them – and again some brachiopod imprints were found...
  23. Hi all, Some weeks ago, I found a site pretty rich in brachipods from the Late Pliensbachian/Early Toarcian in my area (Pedraforca Zone, SE Pyrennes) So, I made a parenthesis in my Upper Cretaceous usual issues, for a change, and I have been picking & preparing them last weeks. This site is very well studied in this paper (in French), and in fossilworks. I probably i found all the species mentioned from the site: Telothyris pyrenaica Telothyris jauberti Quadratirhynchia vasconcellosi Soaresirhynchia sp. Soaresirhynchia (Alméras, 1994) (former Stolmorhynchia) is a genus of little brachiopods first described by Alméras in a study about Portugueses Toarcian specimens, but are common in all the Iberian-Pyrenean Toarcian basin, from Portugal to South France. Unfortunately, they show great morphology diversity, and I must confess the I am not be able to distinguish one specie from another (S.bouchardi, S.flamandi, S.rustica). Maybe @ricardo could help. These are some examples: Homoeorhynchia batalleri And finally, the only Liospireferina falloti I found, though in poor condition:
  24. Recovery and Extinction

    The recovery period after an extinction event may lead to evolutionary bottlenecks. Counterintuitive. https://m.phys.org/news/2019-03-fossils-recovery-extinction-event-evolutionary.html
  25. This weekend we had a quick stop near the city of Mons in the south of Belgium. It is not commonly known that in some forrests in this area are ancient quarries of Maastrichtian phosphatic chalk, not all are accessible but with a reasearch on old maps some of them can be found with a little effort you can clear out a spot on the ground and search for a multitude of small fossils. we only stayed 2 hours, but we did find our fair share of tiny but beautiful brachiopods, bryozoans, shark teeth, dentaliums, bellemnite fragments,... . @Tidgy's Dad , you'll like those little critters and even a few teeth and an echinoid spine:
