  1. I am fortunate enough to have such a huge amount of Middle Devonian Givetian material that I thought it best to put the older Middle Devonian stage, the Eifelian, in its own thread. There are some spectacular fossils here as well though! I thought a good place to start would be in the Formosa Reef, which I believe is quite early Eifelian. This tabulate coral and stromatoporoid reef continues similar complexes found from the Middle Silurian, see my: https://www.thefossilforum.com/topic/84678-adams-silurian/page/3/ thread from page three onwards for details. All these Formosa Reef specimens come from a delightful gift from my good friend @Monica who is a tad busy with life at the moment but is fine and still thinking of the forum. This outcrop can be found on Route 12 near Formosa/Amherstburg, Bruce County, Ontario, Canada. This beautiful-looking specimen came to me with only a third of it revealed but I managed to get it this far after nine days of painful pin prepping. Monica found another one and posted it for ID here: https://www.thefossilforum.com/topic/105528-weird-circular-imprints-formosa-reef-lower-devonian/#comment-1172285 The specimen was identified by another Canny Canadian @Kane to be the little stromatoporoid sponge Syringostroma cylindricum. Hardly a reef-builder, but gorgeous nonetheless. It does have a little thickness to it, but not much. Beautiful! Pretty thin, actually. I love this Monica, thank you!

    ADAM'S SILURIAN

    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.
  3. IDing my Waldron Shale finds is going well, but I hit a snag when getting to Atrypa. My research shows Atrypa reticularis is a common brachiopod found in the Waldron. Also mentioned was Atrypa newsomensis, for which I could not find a picture or description of. My finds include what look like two different Atrypa species but could be the same. There are smarter members than I that hopefully can set me straight on this. The first specimens are what I feel are Atrypa reticularis. The next group are much more ornate. They remind me of Spinatrypa beulla of the Devonian.

    Adam's Early / Lower Devonian

    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 ;
  5. Hi everyone! Yesterday I bought a collection of fossils from a retired fossil hunter, included in the lot was a box full of devonian Brachiopods from the Eifel region (mainly Gerolstein) in Germany. I find Brachiopods very interesting and I am getting better at ID'ing them, but there are quite a few species I've never really seen before and my usual ID website of Paleontica doesn't seem to have most in their database. So I was hoping if anyone here has some handy articles, papers or websites which might help with my quest on ID'ing these critters. PS. I was also planning on posting the ones I really can't figure out, but since I am leaving for Solnhofen tomorrow I wanted to get my hands on some good sources first. Thank you in advance!

  7. Hi everyone! Last saturday we went on a fossil hunting trip with the BVP to Hotton in the Belgian Ardennes. https://www.paleontica.org/locations/fossil/667 There were 2 different locations planned for the day, the first was the "Carrière de Marenne" quarry in Hotton were we spent most of the day. It was my first time at this location, so I didn't have very high expectations but we were very pleasantly surprised by the quality and quantity of the finds which made for a very productive and succesfull trip! Unfortunately like so often I forgot to make pictures inside the quarry... So it will mainly be a report of the finds rather than the excavation. The age of the layers date back to the Givetian stage of the middle Devonian which lasted from 388 million years ago to 383 million years ago. There were 3 spots inside the quarry were we searched for fossils. We started on the east side of the quarry where we found some weathered corals, a bivalve and some bryozoans. One of our friends was very lucky when they found a fragment of Placoderm bone.. the 2nd spot we searched was still on the east side of the Quarry but this time near the big rock outcrop which devides the quarry in two pieces. Here we all hit gold as this was a large area where it was full with weathered fossils in great condition ready to be picked up! No need for hammers here, just grabbing which was laying on the ground as it was littered with corals en brachiopods. We almost collected a bucket full from this area alone. The 3rd spot was the west side of the quarry which was divided in multiple levels. I mainly searched in a large rock pile with some others as it seems these were the remains of an ancient coral bank. We found many large corals here like Hexagonaria and Favosites as well as some nice mineral specimens to much delight of my girlfriend. Someone did do the find of the day here when he found 2 extremely large Stringocephalus brachiopods. I also went with Tom, our group leader to prospect the rest of the quarry but beside some corals I didn't find much more things of interest. At the end of the trip we were given some nice mineral specimens by Tom who found some on the lowest level of the quarry which we didn't visit ourselves. Here the only photo I made inside the quarry, were my girlfriend was building a rock fortress. (Everyone was on a one hour break due to the early summer heat) And here are our finds from inside the quarry: A large Hexagonaria sp. coral which we managed the haul home, one of the perks when you bring a wheelbarrow to a quarry! Another nice Hexagonaria sp. coral And our 3rd large piece of Hexagonaria sp. coral One of the Favosites sp. corals we brought home. Another Favosites coral An our chuncky Favosites coral A weathered Hexagonaria coral. A bivalve we found early at the beginning of the search.

    Atrypha or Atrypa

    I bought a couple brachiopods not to long ago and the information that came with them says they are "Atrypha sp." but when I look up "Atrypha sp." all that I find is "Atrypa sp." I would really like to know if the information that came with them is correct or not. Thanks in advance!

    Atrypa devoniana

    From the album: Lime Creek Devonian Rockford Iowa

    Atrypa devoniana. Can be confused with two other genus species even thought it is low in diversity of shapes. Its shell is fragile, and more likely to be misshaped during the fossilization progress. Juvenile can be easily confused with Spinatrypa rockfordensis.
