Last sunday was my first time hunting this year I went hunting in a place which contains old coast defences. The rocks are Tournaisian in age, probably from the area Tournais, or maybe the area of Soignies. The fossils are Tournaisian aged. I mostly found corals; Caninia sp., Michelina favosa etc. and brachiopods; Spirifer, Aletyphorus, Productus, Leptaenea, Rhipidomella etc. I also found trilobite pygidia from Plitonia kuehnei. When i came home and started unpacking everything i found out i was blessed. I had found a very rare Cochliodus contortus tooth without knowing it. some of my finds : 1: Caninia sp. 2: Piltonia kuehnei 3: Michelina favosa 4: unidentified 5: Cochliodus contortus 6: unprepped, probably Leptaenea analoga 7: Aletyphorus tornaciensis

These fossils are from old coast defences. They are probably from the region around Tournais, the type locality of the Tournaisian. Can someone help me to ID these? I cant find any good literature to ID these. thanks. Jasper

Taxonomy from Poplin & Lund 2000. Description for the genus from Woodward 1893, p 286: "Trunk elegantly fusiform, more or less elongated. Mandibular suspensorium oblique, and dentition compromising conspicuous well-spaced conical laniaries; external head and opercular bones completely ornamented with striations, vermiculating rugae, and dots of ganoine. Fins small, without fulcra, and the rays delicate, distally bifurcated. Dorsal and anal fins triangular, the former opposed to the space between the pelvic and anal fins; upper caudal lobe slender and the caudal fin forked. Scales large and thick, covered with ganoine and ornamented with transverse ridges, usually serrated at the hinder border; principal flank-scales not much deeper than broad, and no enlarged series of ridge-scales; lateral line conspicuous."

Complete newbie with a bunch of new fossils so brace yourselves. The fossil was found in east Clare (Ireland) Waulsotian limestone. This rock is dated Tournaisian - Lower Visean, and is a mix of solid limestone & a brittle lime mud. (Id'd using geological survey maps) "Waulsortian limestone is extensively developed in Ireland, and it represents a phase of submarine bank development during the Tournaisian (Mississippian, Carboniferous). These carbonate buildups are rich in (now lithified) lime mud, contain a shelly marine fossil fauna and generally lack any sign of a rigid supporting framework." Murray, John & Henry, Tiernan. (2018) Lots of crinoid, bryozoan and brachiopod fossils found a round it. It appears to be a part of a longer section (unexcavated). I wasn't able to find anything online that resembled it so would be delighted if anyone could steer me towards an answer. Thanks!

Greetings, all! I am currently writing a thesis involving fossils from the Burlington Limestone near its type section along the Illinois/Iowa border. To demonstrate the diversity of the crinoidal remains from the limestone (over 400 species have been described from the Burlington alone!), I am looking for photographs of articulated crinoids. Do any of you have any that you would like to let me include in my thesis? If possible, I would like high-res images of crinoids identified to genus or species with a scale bar/ruler present in the image as well as the collection/locality info. I can't guarantee that I will use every image posted, but if I use your image, then I will acknowledge you in my acknowledgements and give you credit for the image. Thank you for your time & assistance! -Elasmohunter

Hell All I was going through some micro-matrix from the quarry in Soignies when I found this tiny object. I'm not sure it's a fossil but I wanted to check and it seems to be too symmetrical to be geologic. The piece is 2,5 mm in size. It's found in marine deposits togheter with crinoid parts, trilobites... It's from the Tournaisian (Carboniferous). What do you all think? Picture one shows one side and the second picture the opposite side. It's round and nearly perfectly symmetrical. Thanks already
