  1. This specimen is from the Ordovician Platteville Formation of Wisconsin. The top part looks like a crinoid stem, but the larger disc at the bottom is throwing me off. My only thought was possibly a holdfast. Any thoughts?

    PSA Field Trip

    The club went to the Brownwood Spillway and Wilson Clay Pit Saturday. Weather was spectacular! I decided to skip the spillway and head straight to the old clay pit. Had the place virtually to myself for the first two hours. I headed for a spot that has always panned out with good crinoid material and some nice teeth. I had joked around with the other members that I needed to go there and find the complete crinoid calyx and arms I saw in a dream. Well I found it. But you know how things are always bigger in dreams...
  3. The Paleontolocigal Society of Austin monthly field trip was last weekend - we planned to hit a couple of spots in Brownwood. Well it's a bit of a drive from San Marcos, so I decided to make a mini two day trip out of it and stay in an Air BNB (a great option for traveling these days - no shared air source like a hotel!) . So instead of just the two sites on Saturday with the Society, I headed up to Lake Jacksboro for some solo hunting! And boy was it solo.....not a SINGLE person at the site! I was astounded. Had the whole place to myself for HOURS! It was a beautiful day - 70s and sunny. I c

    Seven-sided crinoid stem?

    This is an enlargment of a photograph I took a while back, where only later did I spot the odd fossil. Apologies for the low quality. I'm curious about the star-shaped object with seven corners. This is from the Madera Group in the Jemez Mountains of New Mexico, which is a Pennsylvanian carbonate shelf formation with abundant crinoids, brachiopods, and bryozoans. I've heard of star-shaped crinoid stem segments with five points, but not seven before. Any ideas?

    Crinoid like ?

    Found st charles county Missouri. Looks like a crinoid segment but no center hole. Instead has like a chip in one side.

    Crinoid like but oat shaped?

    Found in st charles county Missouri. While search for crinoids. These looke like small oat shaped fossils.

    Just a couple crinoids

    Help with ID....

    My wife found this in some talus. It is 5mm long axis. Image was taken with a G9/Oly 60mm with extension tubes (2x). Is this a Crinoid? Looks like the feeding part. Any Ideas on what this fossils is? Keasey Formation, late Eocene. Mostly Mollusk and Gastropods however Crinoids are listed as being found in this location but rare.
  12. Brachiopods orthoceras crinoids all found right here in Hendersonville TN Sumner county just north of Nashville. Love to fossil hunt and see what I can find while imagining worlds of the past.
  13. I did my first microfossil sifting on the sandbars of the Kaw river in Kansas (I posted the trip on the forum ). Anywho, I found this microfossil that reminds me of modern day cowrie in pattern but I'm guessing its a coral? The second I am pretty sure is coral, the third is a worn crinoid segment? and the fourth, ummm I don't have a clue- one side has three parallel ridges- thoughts? Appreciate all the help as always! Bone
  14. I had some spare time this past weekend, and a fossil hunt sounded nice. Bad weather had made that impossible the previous month. The weather was great out finally, so I went out Sunday (3/7/2021) to good old Truman Lake to look for Burlington Formation crinoids. I mainly just wanted to find and keep nicer, intact crinoids that day. It's a good walk to the crinoid hunting grounds from my car, and there is fossiliferous chert material along the way. I decided to split one chunk of chert, which contained only one single platyceras gastropod steinkern. After finishing work on it, I hi

    Snow thaw

    I needed to get out of the house for a few hours and so went to try my luck at finding some local Silurian fossils. First outing of the year. My first best find was this crinoid which I believe is a Eucalyptocrinites crassus calyx. A good size. On the reverse side is a small Encrinurus egani. This next find I was pretty excited about. A large D. platycaudus cephalon. I took it home to prep... Unfortunately, the preservation was not ideal, but that's the way the cookie crumbles. I placed a nicer example next to it

    From the album: Platteville to Decorah formation Ordovician Twin Cities

    Larger picture of the same trilobite. Just to show an example of upper Decorah twin cities hash plates. Certain crinoid species are very strongly represent compare to middle and lower Decorah Formation. The largest crinoid species is often in single pieces or sizable stem pieces but head and suction portion are unusually absent. In Middle and Lower Decorah formation, the density of crinoid fossils tend to be lower.
  17. Work and weather have kept me from doing much fossil collecting these last couple of months. But I was finally able to photograph finds from my last outing. I found some interesting stuff I think. We'll start with my favorite find.. This is the large blastoid Xyeleblastus magnificus. They're always found crushed to some extent (even the holotype.) This is only the second blastoid I've found in the Fort Payne! Did well with the crinoids that day A very nice Agaricocrinus sp. with the stem attachment point exposed (they
  18. From what I've learned crinoids aren't from around here, prob from way upstream fill rock. Here being Dallas creekbed in Eagle Ford shale. Its so unique with the patterns, almost looks carved, just guessing part of a crinoid because of the cylinder shape. What the heck is it?
  19. Any feedback on the authenticity and quality of these 2 fossils? I'm assuming the quality of the brittle star is not top notch, as the seller didnt provide close up photos but fir the right price, I might still buy it if it is authentic. Any advice will be much appreciated as I learned a lot from my recent post of a similar nature!
  20. Hello, I believe this to be a "holdfast" from the Crawfordsville Indiana crinoid locality. I am hoping that someone could help with identification of the particular species, and also if there is a scientific name for "holdfast." Thank you!
  21. Hello, I am hoping that someone can please help me identify the four species of crinoids on the attached plate? I have numbered them for reference and show close-ups. Thank you in advance!

    Part of crinoid crown?

    Hello this is my first visit here, and no I didn't go on airport property but was on the border at a small tributary. I have found a lot of crinoid stems on the past and this looked similar, my best guess was part of crown. Am I close? I included couple pics of bivalves and an ammonite found in same place if that helps.
  23. One of the nice things about being on the team to design a new facility is you can get what you want. All retaking walls and benches are locally quarried Stoner Limestone from Weeping Water, Nebraska. I can’t wait to get my scribe and chisels out...

    Substrate?

    There are fossils in the background gray sedimentary, but so much better preserved in brown! Why? Almost like this pile of creatures is on display, a 7 inch blob just laying on top of gray stone. I'm more interested in how these were preserved than what they are.
  25. I wanted to show a fossil I found years before I ever joined this forum or took a step in the Cretaceous brooks. This is a Crinoid specimen I found about 20 years ago at the Delaware River in Burlington City, NJ when I was a kid. The Deleware River has a good amount of fossils brought down here from the glaciers. At the time, I did a horrible job prepping (if you can even call it that) this fossil and pretty much destroyed the middle of it. A few months ago, I re-discovered this in a closet at my parents' house. I took some time, polished up the middle, did a little trimming, and n
