  1. I'm not sure if folks would like to do this or not, but I thought it might be fun to have a run of "I Spy" with a large fossil-rich rock that I recently found in our yard. Experts and newbies both welcome! This rock weighs 4 pounds and measures about 6 inches by 5 inches. These are macro images - all from the same rock. Check them out and see what you can "Spy" in each image! Look closely - very closely! And think in 3-D format! ;-) A bit of background - this rock was found in Huntsville, Alabama and is likely mostly limestone. I mostly find fenestellan bryozoan, crinoid, and coral fossils, with a few bivalves. So, surprise me with what YOU see in these photos!
  2. Is this a crinoid stem?

    Is this a crinoid stem? If so, what is the exterior? Thx! From Kosciusko Co, IN.
  3. Are these Crinoid Stem?

    These were found in the same place, in black shale, in West Virginia. Are these both crinoid stem? Thank you for your help!
  4. ID verifications?

    Along with being a newly avid fossil student, I am also a stock photographer. I would like to submit these images for stock images, but I want to make sure that I am identifying them correctly. You guys have helped me learn EVERYTHING you see here! All of the names and labels, I learned here! Please let me know if I am missing any thing or have mislabeled any of these? I have numbered them to help with the identification. Thanks so much! Ramona
  5. Got to visit one of the Pennsylvanian era sites outside of Brownwood TX with the Paleontological Society of Austin (FIELD TRIP!) and was astounded by the variety of fauna and the COLOR! Rocks in green, burgundy, purple and golds. Consequently, so were the crinoid stems! A rainbow of Crinoids! I was happy to find one little piece of an arm, also. Was hoping to find a bulb, but did not...one of the other field trippers did though! Also, lots of beautiful horn corals, bryzoans, horn corals, a big and a little Belerophon gastropod, big and little brachiopods, some neat crinoid "spikes" and what I think are Echinoid mouthplates? Aristotle's Lantern parts? Confirmation or correction please! My best find of the day was a little hash plate of echinoid spines and tiny tiny plates. I was also happy to find a cidarid plate and spine. Still looking for that whole one!! My other "big find" of the day was a Petalodus shark tooth...sadly, just the root. But it would have been a BIG one! I spent 5 hours hunting and could have easily stayed another 3 but it was a bit of a long drive home. I look forward to going out again! Rainbow crinoids: Echinoid Hash Plate: tiny piece of Crinoid arm Echinoid Mouthplates? Or Crinoid parts? Crinoid Spines: Not sure if this is another crinoid spine or something else? Petalodus tooth Root: Belerophon Gastropods Bryzoans Neospirifer Horn Corals Punctospriferer Brachiopods Fusilids?
  6. Met a very nice man this evening that finds a lot of fossils in his quest for arrowheads. He gave me this fantastic piece and well as some other nice things I’ll post later. I have several triobites and Ptychodus shark teeth and other stuff all have to me. He told me this Crinoid came from a creek in green county Alabama and that’s all the info I have on it. He said when he didn’t have anything else to do he would work on trying to reveal this a little each time.
  7. Whitby area finds

    Went to a beach in the Whitby area today, it was very slim pickings until my daughter saw the first of these items shining amongst the rocks. I’m guessing some kind of pyrite bivalves? The second item is something I saw on our way off the beach, am I right in thinking they’re crinoid stem sections? Thanks in advance
  8. Amazing Arizona Adventure II

    I went back to my very productive Devonian Martin Formation and Mississippian Escabrosa Formation near Superior, Arizona to retrieve my large single crinoid head fossil. Amazing Arizona Adventure original post link After some acid prep four crinoids and one blastoid were clustered together. Currents probably sorted them by size and shape. Several more hours of acid prep made the remaining four best ones stand out. I had to carefully break away pieces of shell that adhered and covered the crinoids and blastoid. Careful monitoring of their progress prevented any of them falling off the matrix. The resulting piece is probably the finest crinoid and blastoid assemblage ever found in Arizona. Finding one crinoid or blastoid cast in Arizona is very hard let alone four or five together. The two largest crinoids in the center and left are likely Physetocrinus lobatus. The upper right is an Orophocrinus saltensis blastoid. The lower right is an unknown crinoid. (Any idea what it is?) The field of view is about 7.5 cm wide. Keep looking for updates as I prep and post more fossils. I found several loose crinoid heads.
  9. Bryozoa or something different?

    Hi All, I picked up this rock in my back yard a couple of days ago. I picked it up because I saw a couple cross sections of rugose coral and some fenestrate bryozoan fossil pieces. When looking at it later, I noticed this feature. I haven't found anything like this before. Is this just a different type of bryozoa? These little marks also look like some tiny Platycrinite crinoid pieces. This was found in Howell County, Missouri, USA. It came from the Ordovician Period. These lines measure approximately 23mm in length and measure approximately 0.79mm wide. The individual spots are oval in shape and measure approximately 0.38x0.79mm. I don't know if it shows well in the first image, but this feature appears to be in a fracture in the host rock. There is still some rock covering the feature in the fracture. Any assistance or direction that you can give me is greatly appreciated. Thanks for your time, Doug
  10. I am considering buying a floating crinoid fossil, and the seller claims they’re “rare.” Is this true or is he just trying to make a sale?
  11. Crinoid stem or segmented worm?

    This is not a fossil that I am familiar with, but I have done some research and it looks a bit like a crinoid stem? The segments seem fatter than the stems I saw online, but that was as close as I came... Could it be a bryozoan segment? I didn't see any of those online that matched it, either... Found in Huntsville, AL, where I usually find fossiliferous limestone with crinoids and fenestellen bryozoan fossils. Thanks! Ramona
  12. Fossils in quartz?

    I continue to be amazed at the plethora of fossils in our yard, so I tried an experiment. I raked up some rocks that were around a tree in our front yard and half filled a five gallon bucket with them. I figure that some of them were brought in as decorative rocks, but to test that theory I grabbed two from the top at random. I cleaned them with vinegar and water and then photographed them with my macro lens. They are at least a different type of rock than I am used to seeing (not all of these are different, but those two were). I mostly see limestone, but I will post photos of these in the comments. They look like quartz to me? Or are they a different type of limestone? And maybe I am imaging it, but I think I am seeing some crinoids and bryozoans in them? If no one else sees them I will circle what I THINK are fossils for further verification. Is it odd to find an area so rich in fossils? Or am I odd in that I am looking so closely for them, LOL? I guess since this area was once covered in water, it is likely "normal" to find bryozoans and crinoids everywhere I look, right? Thanks for all input! I learn so much here! (And I won't be surprised to hear that the following photos really ARE rocks that were likely brought in as decorative, LOL!) Ramona
  13. I am really trying to learn my common invertebrate fossils. Can someone, once again, confirm my tenative identification, or correct me? I really appreciate it. The fossil in question is this oval fossil. After doing some research my guess is it is a crinoid of some sort. I am guessing that the little "nipple" in the center of the oval is where the normal hole is, but why does it have a line disecting the oval into two distinct parts? If it is not a crinoid, can someone please tell me what I am looking at, and where I went wrong on my identification? Thanks, Doug
  14. My First Alabama Fossils

    Got these in the mail today and got them off a auction site. My first of anything from Alabama and I love them. Crinoid fossil stem echino derm sections rugosa horned coral fossils these were found along the Tennessee River in Florence
  15. Went to a fossil garage sale, were the person was selling off his collection, this fall with low expectation. Found what turned out to be a very nice specimen of a Devonian Crinoid after prepping it out. My friend Tom W. tells me it is more than likely an Arthrocantha carpenteri. Wish I knew what quarry it came from, it wasn't labeled.
  16. Klein Quarry IA Crinoid

    Below is an example of a Box Crinoid I was lucky to find in 2017 with the Cedar Valley Rock and Mineral Society in 2017. This quarry can produce Devonian Phacops, Greenops, Crinoids and Fish parts, besides lots of brachiopods . Been going here and the Conklin quarries for close to a decade. Finally found a complete Crinoid. This one is a Camerate Crinoid, more common name Box Crinoid.
  17. What might this be?

    I have been able to identify (with your help) a few of the fossils we found while hunting at Beltzville state park. This is something that may be something. I tried to get the six-sided pics as recommended. What might this be (if anything)? Beltzville State Park in Pennsylvania, USA. I believe these come the Upper Devonian Mahantango Formation. Thank you.
  18. Crinoid holdfast 3D

    Have you ever wondered what the holdfast root system looked like? I did. So I prepped one of my least costly duplicates to see the whole picture. Here are the before photos.
  19. Crinoid ID from Keyser formation

    Hi all, Another couple of mysteries that I found at an old quarry near Mapleton, PA and are from the Keyser formation which is thought to straddle the boundary between the Silurian and Devonian periods. The layers they were found in were close to layers of the Tonoloway formation which is Upper Silurian in age. I found one item that I believe is a Mariacrinus pachydactylus based on the Paleontology of New York, Part 3, Vol 2, Plate 3. It's been preserved by a black colored Chert but I don't want to acid etch it any more that I have (about an hour in vinegar). The other oddball is this UFO shaped specimen. I've found similar examples before but I ruined any chance of seeing detail on the surface by soaking them in vinegar. This is the first example I've found since then. Close examination with a lens and microscope does not show any detail so it may need to be cleaned a bit more. The "Bottom" has a nick in it or maybe it was where a stalk attached? Any thoughts? Thanks for looking!
  20. crinoid ?

  21. I think this might be a sea lily?

    I picked this up off of the shoreline of Norwood, Michigan this summer. Initially I just thought it was a weird, pretty shell fossil. Until this morning, when I read the recent Atlas Obscura article about sea lily fossils (https://www.atlasobscura.com/articles/sea-lily-fossil-utah-evolutionary-mystery). The bit that caught my attention was that crinoid fossils often segment into little 'cheerio' shapes. I have SO many Norwood specimens with the distinctive cheerio on them (see the second image, left), and it got me thinking that the white frond shape might be a sea lily? Anyway, I'll be happy to learn whatever it might be, as it's definitely one of the weirdest things I've ever found on the beach. Thanks! Made In Michigan
  22. Hi All I found this rock earlier today and was surprised with what I saw. There is what might possibly be three different fossils in it. If anyone can please tell me if these are fossils, geology or a mix, I would appreciate it. This rock was found near Willow Springs, MO. A - Measures 8mm on the longest side. B - Measures from side to side approximately 19mm. It doesn't show up well in the image, but there are five total sections in an almost fan shape. Is this crinoid stem impressions or something different? C - This one is one that I am guessing might not be a fossil. These little "lines" remind me of tiny bones in their appearance. On average, they measure 3mm long and about 0.33mm in diameter. If anyone can shed any light on any of these areas of interest in this rock, I would greatly appreciate it. Doug
  23. I haven't posted in a while, due to traveling and then starting a new job, but I find it hard to stay away from the rocks in our yard. We recently moved into a house (Huntsville, AL), where I soon discovered that we had a wooded area with a creek bed full of fossils. From what I have seen so far they are mostly common bryzoan, crinoid, etc fossils in what I have learned is fossiliferous limestone (mostly). I ventured out today and photographed some rocks, as there are simply WAY more than I can bring into the house to study. I am wondering about this rock... According to what I have learned here, it is likely limestone with fenestella bryzoan and crinoid fossils? Oh, and the hitchhiker looks like some sort of insect. LOL It's well camouflaged, so you might have to zoom in to see it. If I am correct on this identification, the thanks goes to you guys! Ramona
  24. For your viewing pleasure. Sharing with the group.
  25. Help Id'ing Crawfordsville Crinoid

    Hello, I recently unpacked from an old collection this crinoid specimen from Crawfordsville Indiana. I would appreciate any help identifying species. The slab measures 13 x 14 cm, the detail is 7 x 6 cm. Thank you!
