    Shale pit - Hamilton Formation Finds

    Afternoon esteemed FF community. I'm new here and was hoping for assistance in identification to aid building interest in fossils for myself and my young kids. My 5yo son has been fascinated with fossils and I'm hoping to learn more myself so I can help shepherd his interest. We went to a nearby shale pit in central Pennsylvania that according to the geological map from the area seems to expose the Hamilton Group of the Devonian Period. My son had a great time scrambling around and we came home with some interesting finds that my limited fossil knowledge can't identify beyond "brachiopod" or "crinoid". Any help would be greatly appreciated and if more pictures are needed let me know; I was hesitant to upload too many. Also, as an amateur I'm finding it difficult to know what diagnostic features to pick out to aid in identification so any tips would be greatly appreciated as I learn more. The scale for all the following images is in Inches (sorry I didn't have a metric ruler I could find at the grandparent's house). Thanks! Item 1: Item 2: Item 3: Item 4: Item 5: a rock that I split on site, my amateur work left an unfortunate scratch on one side. My eye picks out crinoid? and brachiopod? Item 5 bottom closeup 1: Item 5 bottom closeup 2: Item 5 bottom closeup 3: Item 5 top closeup 1: Item 5 top closeup 2: Item 6: Crinoid stem? Item 7: Crinoid stem impression?
  2. Good afternoon. Today I want to show 3 types of crinoid limestone (polished plates) from different places in Ukraine. First one. Place of discovery: Ukraine, Donetsk region, Dobropolsky district. The age of it is the Kasimovian stage of the Carboniferous period (307 Ma). 4.mp4 5.mp4 6.mp4 7.mp4

    I found this Crinoid on Charnmouth beach, Devon, U.K. I am currently trying to label my collection and I was wondering if anyone could tell me what the full species name is and an age of the fossil? Thank you in advance.

    Dorycrinus missouriensis

    From the album: Mississippian fossils

    An amazing Dorycrinus from the Burlington Formation of Missouri. Perhaps my favorite specimen.

    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.
  6. Hello there, I'm a first time poster so I apologise if I've missed anything off or done anything incorrectly, I tried to do my best with pictures. All of the attached photos are of beach finds found between chapel point and skegness, lincolnshire in the UK, so I can't give any detail on what formations they came from sadly, although we get a lot of wash down from the Yorkshire coast and the carboniferous formation in Northumberland. I've hazarded a guess at a couple of them myself, but would really appreciate someone else correcting me or confirming my thoughts. Again, I apologise if anything isn't up to spec. Thanks.

    Azygocrinus on encrinite plate

    A photo I forgot I had taken of an Azygocrinus rotundus calyx on a nice encrinite plate.

    What is this called?

    Besides; Crinoid....Is there a specific name to this thing? Or if it's a piece of something, what is that name of the piece? Just wondering, trying to get more info. Thank you!

    Crinoid arms???

    I found this sample in southeast Kansas (Chautauqua co.). It has what looks to be crinoid arms on it but I’m not for sure. The arms look to be made up of small segments. Any helped would be appreciated.

    Not sure

    I found this bad boy in the creek today. The hole is completely through the center and it has characteristics of a crinoid stem. I looked them up online and from what I've gathered there's 5 types maybe. Whatever this is resembles one of the 5 types. I thought maybe it was wood but there's no rings and the color doesn't match to fossilized wood. Could this in fact be a crinoid stem ? For the record it was found in middle tn.

    What type of crinoid?

    I found this in southeast indiana and I am wondering what type of crinoid this is?

    Megistocrinus farnsworthi

    From the album: Mississippian fossils

    This Megistocrinus best matched with farnsworthi, though it is possible it could be a different species.

    Crinoid fossil?

    Hello! I’ve been doing some fossil and rock hunting on a Lake Michigan beach in Wisconsin, and I was just wondering if this could be a crinoid fossil? There’s chain coral in the rock on both sides. I tried sanding a little around what I think is the crinoid, but I didn’t uncover anything else. Thank you for any help!
  16. Severy Shale, Pennsylvanian of Kansas. Site is mostly brachiopods, gastropods, coral, small straight cephalopods (mooreoceras) and rare trilobites. I'm guessing it may be a partial crinoid calyx but the spines don't look like any of the crinoid pieces I've found in our area. The spines I've found have narrow bases to fit between plates and all the plates ive seen here have a flat surface.

  19. Hello to all. Found this sample few years ago. Place of discovery: Ukraine, Donetsk region, Dobropolsky district. The age of it is the Kasimovian stage of the Carboniferous period (307 Ma). Have a nice day

    Crinoid ID

    I am having trouble identifying this specimen. I have not found or seen another like this, so I'm hoping someone will be more familiar with it than I am. It looks clearly crinoidal like a calyx, and comes from the Burlington Formation of Missouri which contains a large fauna of crinoids. I considered Rhodocrinus, but I don't think that is correct. The calyx looks like it has 2 rows of "spines". I currently lack an air compressor and air abrader, so this specimen cannot be cleaned any further due to how fragile it is. Any ideas?

    Shale splitting

    As I have learned more about fossil collecting I have been limited to surface collecting. But I have wanted to learn how to split shale and what to look for when searching for various cross sections of trilobites, crinoids, etc... in my area. Are there any books or articles I should look through and read, about shale splitting for the Indiana, Ohio and Kentucky area.
