  1. Isotelus bits?

    One lives in hope. From one of my favourite hash plates, sent to me by my wonderful friend Ralph @Nimravis Southgate Hill road cut, St. Leon, Indiana, USA. Cincinnatian (Late Ordovician) Waynesville or Liberty Formation. Is this part of an Isotelus thoracic segment? Thank you so much for looking and any help is very gratefully appreciated. 11 mm across. And is this a bit of Isotelus? 2.2 cm long.
  2. Hypostome?

    Hello, my friends. This specimen comes from a wonderful hash plate, maybe my favourite hash, that was kindly sent to me by Ralph, @Nimravis It's from the Southgate Hill Road Cut, St.Leon, Indiana, USA and is Cincinnatian (Late Ordovician) in age, probably the Waynesville Formation, judging by the brachiopod assemblage. But could be Liberty. Is this a trilobite hypostome? And if so, is it likely to be Flexicalymene? The piece has several Flexi bits on it; a couple of pygidia and some free cheeks, the reverse has three cranidia. But I think there are Isotelus fragments present, too. The specimen is 5 mm wide. Thank you very much as always for any opinions and help.
  3. Nautiloid ID

    Hello all, I found this nautiloid fragment in the Kope Formation out of the Cincinnatian series in Northern Kentucky. Suspecting this to either be an Endocerid due to the size or perhaps even a coiled nauitoid due to the curvature in the camerae towards the end with the siphuncle sticking out and the general shape of the specimen, unfortunately not preserving detail towards the other end. I was thinking it could be Characteroceras due to them being found in the Kope, but it seems to be too big. Seems like this guy died, sank to the bottom and preserved the side that planted in the Ordovician mud, interesting that you can still see the outline of the siphuncle on that end. Curious as to what you all think, I just don't know what to put it in as for my database. Thanks you all!
  4. Hey, all! I have a surplus of Upper Ordovician (Cincinnattian series) and Silurian fossils from the Dayton area. Fossils include diverse brachiopods, horn corals, orthoconic nautiloids, and bryozoans as well as trilobite fragments. Would anyone like to trade for these fossils? If there's anything in particular that you'd like from the area that I don't already have in my collection, then I may be able to go search for it before the trade, too. If anyone expresses interest, then I'll upload images of said fossils in the next few days. Let me know!
  5. Trilo Bit?

    Here we have a photo of a hash plate which has bits of bryozoa and crinoid ossicles, but is that a trilobite genal spine? The rock is Upper Ordovician Kope Formation or Fairview Formation. Economy, Southgate, McMicken, Mt.Hope or Fairmount members/formations if you like. Lawrenceburg Road cut, Indiana. Thanks all for looking.
  6. Finally was able to get out on the river for my first hunt of the year, the water receded time to see what the winter flood brought. I found some big layered slabs of Ordovician bits and pieces and am looking forward to cleaning them up to see what I got. Also found a beautiful mussel half, full of pink mother of pearl. I left it as I found it as Indiana law requires. Was great to get out!
  7. Picked this rock up while fishing the river over the summer. Since it's to bloody cold to do anything outside I figured I would clean it up and see what all the bits and pieces are. I think it will be pretty when it's done, although some of the fossils are eroded. It's like where's Waldo? See anything?
  8. Curious about this one. ID?

    This one is storm battered, broken brachiopods but what I'm curious about is the other half of this hash plate. Running down the center is a ridge that is part of the tongue shaped fossil, hope you can see it okay in the photos. Thanks in advance!
  9. I've been trying my hand at prepping this hash plate that I found on the Whitewater River in Southeast Indiana. Gotta do something when the river is high and the weather sucks!! There is a lot of bits and pieces going on in this one and the color of the fossils are odd compared to the matrix they are in which is really soft. Thought I'd share, what caused this jumble of fossils, and what do you see?
  10. This weather has got me a bad case of cabin fever, my normal fossil hunting ground along the Whitewater River in Southeast Indiana is flooded. Went out in my back yard today to look thru the two truck loads of leach line gravel I bought for landscaping, the quarry is only about a 1/4 mile away. Found this odd ball, thin layers of crystal like formations on both sides, has hollow cavities and some brachiopod fossils that are a red color. Just curious as to how it formed, wish I could get closer photos of the brachiopods, will try again tomorrow with some daylight....if the sun ever shines again LOL.
  11. Possible Amplexus?

    Found in Southeast Indiana on the Whitewater River. I find a bunch of Grewingkia but this coral looks different, has a deeper chalice and wider at the top compared to the length. Thanks guys!
  12. cf. Treptoceras duseri

    Here is an orthoconic nautiloid (cf. Treptoceras duseri) from the Cincinnatian of Ohio that I just completed. It is ~30cm (12 inches) in length. Unfortunately, I forgot to take "before" photos. I cut away about 75% of the plate it was in. About 50% of what you see of the fossil here was covered with matrix.
  13. In search of the elusive isotelus

    For the month of March I will be in Ohio working and am hoping someone can point me in the right direction to find some Ohio trilobites. Even partial large isotelus and flexis are fine. Maybe an Ohio crinoid as well. I hope someone can help and maybe even meet up and we can collect together!
  14. Sorry guys I'm back with more Brachiopods. Usually the ones I find are embedded in matrix but these are nice ones, found near the Whitewater River. I've been going thru my ID book and wonder if my stab at identification is right or wrong, I learn either way. Once again thanks again for your help! Using the fourth photo with the shells right side up and with a ruler. Top left and middle are they Rafinesquina? Top right is that Holtedahlina? Bottom left Platystrophia? Bottom right Plaesiomys?
  15. I've found a blob me thinks. Came across this on the Whitewater River, Southeast Indiana. What the heck do you think is in this? I see a Leptaena.
  16. I found this conglomerate, or hashplate of Brachiopods on the Whitewater River, Southeast Indiana and wonder what they are. It seems like a cross cut of the ancient Ordovician sea bed because all the fossils are on top of rock that seems layered. I've been slowly working on my first prep, from left to right using sewing machine needles, I don't want to mess it up!
  17. Ordovician Brachiopod Id?

    I found these brachiopods on the Whitewater River, Southeast Indiana within the Cincinnati Arch. Was trying to identify them with my book wondered if they are what I think they are. The one on the left, the shell with the groove in the middle, could it be Platystrophia? The small shell bottom right, Hiscobeccus? The cluster of shells on the top, I have no idea. I appreciate how help you all are!
  18. With the mild December weather, I decided to squeeze in one more collecting trip before the end of the year. I contacted a few friends and we hopped in the car and made a six hour trek from the Chicagoland area down to Northern Kentucky. We decided to collect a huge roadcut outside of Maysville Kentucky. The cut is well known to collectors of Cincinnatian aged fossils. Many beautiful crinoids, edrioasteroids and other rare Ordovician fauna have been found at this site. The cut is enormous and is quite overwhelming to a first time collector. I have not done much collecting in the Cincinnatian but had had a chance to briefly visit this site once before and it looked promising. The site cuts through several formations of the Cincinnatian. From bottom to top, it exposes the Kope, Fairview and Bellevue Formations. My main goal was to hopefully find a rare edrioasteroid. We initially concentrated on the upper layers in the Bellevue. We had already had some luck earlier in the day with echinoderms. We had stopped at a smaller cut on our way to the site that exposed the Kope Formation. My friend found 2 nice slabs with well preserved examples of the Crinoid Ectenocaris with stems and calyx’s preserved. Unfortunately, we did not have much luck locating any Edrioasteroids. I decided to head down the cut and do a little prospecting in the Fairview. Almost immediately, I stumbled upon my best find ever in the Cincinnatian! I was looking at pieces of shale when I was stunned to see a slab covered in trilobites! For those who have not collected in the Cincinnatian, finding any trilobites other then Flexicalymene and Isotelus is a rare occurrence. A collector is likely to only find isolated parts of some of the rarer types. The trilobites that you do find are normally individuals and likely enrolled. After closer inspection, I was amazed to see that the trilobites that were preserved on this slab appeared to be examples of Ceraurus milleranus! All appear to be prone and some are even piled on top of each other. Finding one complete Ceraurus in the Cincinnatian would be considered an amazing and very rare find. In all, we collected over twenty in various stages of growth ranging from a tiny 1/4 inch example to one nearly two inches in length. The slabs need to be cleaned and prepped but I am attaching a picture of one of the unfinished pieces. I will add more pictures to this post once everything is prepped. We found some other nice fossils that day that I will post as well.
  19. Being an amateur fossil collector, yet long time "rock hound", I became interested in learning and discovering what these fossils I picked up were. How did they come about and why? I live within the Cincinnatian Arch even though I'm in Southeast Indiana, it's a small area and Ordovovician in nature. But this book helped me understand what this area looked like, the stratification, and information of the fossils most commonly found here. I'm always looking for books and knowledge, so glad I found this forum!!
  20. I've been sifting through a bucket of dirt I collected on my last dig in Cincinnati. I've come across these two pieces that has me scratching my head. Are they ammonites, snails, arms of a Isorophus? Not the most glorious finds but two that I am having some trouble while cataloging. Thanks all!
  21. So, It's been a while since I've posted a trip report but I had some success this weekend with finding those elusive Cincinnattian trilobites that have flummoxed and avoided me for years. While on my way out to the St. Paul, IN quarry open house on Saturday, I stopped off at the St. Leon (South Gate Hill) roadcut in Indiana. I'd heard that there was a layer of "butter" shales that produced Flexicalymene trilobites. I've tried to locate it in the past with no luck but I decided to try again this time. I was successful! Thanks to some observation of another collector that was working the East side of the roadcut I figured what level I should be at on the West side. Then it came down to just looking really hard: Those are the first two of five total rollers that I found. They are waaaaaay tiny but I was happy to finally have found some on my own. Then, on Sunday, I hit up a roadcut near Bedford, KY with fellow member Kentukiana Mike and I found a yuuuuge one: The St. Paul quarry was pretty cool too. I didn't find any whole trilos but lots and lots of brachs and Eucalyptocrinus caylxes. So I'm pretty happy with this trip between the Trilobites and other cool stuff I found. I'll have to post more detail later once I get pics. Dave
  22. Bryozoan Fossil?

    Hello all, I'm working on a project for my Geo 200 class and I am having some trouble identifying the fossils on a rock I was given (pictured with the white bar representing 2 cm). I believe it's Bryozoan but if you have a better explanation please share. Thanks!
