  1. Hello dear members, in this post I'll show you the fossil bonanza of Caesar Creek State Park, near Waynesville, Ohio. This summer I spent a day collecting fossils in Ohio and I visited three sites: Trammell (I talk about it here http://www.thefossilforum.com/index.php?/topic/98830-trammel-fossil-park-ohio/), Oakes Quarry and Caesar Creek State Parks. The latter was the best, both for finds and general experience. It is in fact regarded as the most accessible fossil hunting locality on Ohio: over 150 m (500 ft) of fossiliferous rocks are exposed, due to the works for the constuction of an emergency spillway back in 1978. Since then it has attracted the attention of paleontologist and amateurs. In order to collect, you have to sign an authorization at the nearby Visitor Center and you cannot use tools or collect specimens that are larger than the palm of your hand. Nevertheless, you'll find and be able to keep some exceptional material and I consider my experience as the best ever in a fossiliferous locality! Three formations crop out: Waynesville, Liberty and Whitewater formations. They date to the Upper Ordovician, a period when Ohio was covered by a shallow inland sea and was characterized by a tropical to subtropical climate. Beds of limestones and mudstones formed as the result of storm waves and currents; in a few cases the effects of super-hurricanes and tsunamis can be recorded. the fossil assemblage is dominated by clusters of brachiopods, bryozoans and horn corals. aragonitic fossils, such as bivalves, gastropods and nautiloids are preserved as internal molds. articulated and frequently enrolled trilobites can be found, as well as fragments of Isotelus, a very large trilobte and State Fossil of Ohio. In the Visitor Center a small diomara shows the Caesar Creek biota as it apparead in the Ordovician, alongside some fossils, including a perfectly-preserved Isotelus specimen. In the field, I collected fossils only from the ground, not on the walls (where you can only take pictures). i found a lot of isolated specimens, here I show the larger and more impressive clusters. Let's start with a picture of a section of the exposure And now the fossils! In the clusters, many kinds of fossils are preserved, in particular brachiopods and bryozoans, of which many species can be found. Horn corals are easily distinguishable: In this case, I think the cephalon of a trilobite can be seen: This was a huge Bryozoan cluster! And now, my favourite specimen, the genal spine of an Isotelus trilobite! Finally, a picture of me holding a rock densely-packed with bryozoans and brachiopods. all right, that's all! I hope you liked my post. I really loved the experience at Caesar Creek: everywhere you looked you could see museum-quality specimens. I spent only a couple hours at the site, but I have never seen so many fossils in a single place! I higly suggest anyone to pay visit, you wont't be disappointed. Thank you, Fabio
  2. Tristate Trilobite Hunt

    Hi all, This week I'm heading to the tristate area (Ohio, Indiana, Kentucky) for a trilobite hunting trip. It's unusual for me insofar as it's being run by my university. Usually I do my own recon, but since I don't really know where I'll be going (I assume we'll be visiting fairly well known localities), I was wondering if ya'll could help me out. I'm trying to figure which sites are famous in the area, and which layers to look in at those sites etc. I'd appreciate any info or advice! I'll be sure to return the favor by posting a full trip report when I get back.
  3. Trilobite Fragment?

    From the Caesar Creek Spillway in Ohio. Much detail was lost in my feeble attempt at prepping. What’s exposed here is probably just under an inch long; it’s pretty small.
  4. ID assist bone? Rock? Drilled or natural?

  5. Marine Fossils (Ohio)

    Figured I’d post one more while I’ve got the collection out. When I was younger, my grandfather had a gravel driveway put in. I assume it came from Ohio, although I have no idea in truth. I frequently picked through it and found a few fossils. The gravel is clearly made of marine sediment for the most part - I’ve found brachiopods, trilobite fragments, shells, etc. I just wonder what these two could be? The first one has a couple of different structures in it - I’m thinking sponge or coral for the main part. The second, I have no idea. It looks footprint-ish, but this doesn’t make sense due to the marine nature of the gravel. Any ideas? Thanks, Nate
  6. Tooth

    Walking the shore line tooth was found on beach. Looks like from a large mammal? Any idea which mammal it came from? thanks for any help you can provide
  7. Hey, all! I would like to hunt for fossils in or near Columbus, Ohio. Do any of you have any recommendations for locations to hunt or resources that I could consult? Thank you!
  8. Hello everybody! This summer I had the pleasure to collect fossils in a few famous Ohio localites. I want to start with the first that I visited, the Trammel Fossil Park in Sharonville (Butler and Hamilton counties). The park is a 10 acres fossil-rich hillside and woodland area, that was donated to the city by a local developer. Ordovician rokcs crop out and they are very productive! Collecting is free for everybody, tools can be used, but you are not supposed to remove large boulders of rock. The space in front is equipped with tables, benches and boards that explain the geology and faunal assemblage of the site. Here, 4 formations are exposed: Fairview, Miamitown, Corryville and Bellevue, that date back to the Late Ordovician. The most abundant fossils are a few different species of brachiopods and bryozoans. Less likey you can find crinoids, gastropods and, for the Miamitown section, even Edrioasteroids. I'll let the boards explain more specifically. Let's talk about the actual collecting! Picking by hand is the preferable method, for bryozoans lie on the ground or they can be easily freed from the rock. Brachiopods are usually broken and less easily removable, but you can find some remarkable specimen too! Overall, I was more than satisfied! I filled a small box with the best preserved fossils and had a nice chat with a fellow fossil hunter! Trammel is definetely a family-friendly location, easily accessible and risk-free. Findings and fun are guaranteed!! I'll add the pics of my finds later on in another post, wait for it
  9. Hello friends! Thix summer, after visiting the Orton Geological Museum (you can find my post about it), I paid a brief visit to another museum in Columbus, Ohio. It was the Ohio History Center, that featured an extensive history of Ohio from the geological past to present. Focusing on the fossil exhibits, they are predominantly educational, for children I'd say and sadly most of the label lack specific informations (scientific names, origin). Nevertheless, there are some very peculiar fossils, that I'm going to show you now. Let's start with one of the highlights of the whole museum, the Conway Mastodon, a complete skeleton found in 1887 in the Ohio countryside. The Ice age exhibit features three other bone remains: those of a stag moose, a flat-head peccary and a woodland muskox skull. The other cases display fossils from the Palaeozoic. the Ordovician section consists of an Isotelus trilobite (state fossil of Ohio), a large crinoid slab and other fossil taxa (like bryozoans and nautiloids). From the Devonian you can see large colonial corals, nautiloids and a huge trunk (or branch, I'm not sure) from a tree of the genus "Callixylon". The Carbonferous section features fossil plants, like the well-known calamites, sigillaria and the fern "Pecopteris". Finally a huge fossil tree stump of the genus "Lepidodendron" concludes the exhibition. Overall I was satisfied, for you have an overview of all the kinds of fossils that you can find throughout Ohio, from the Ordovician trilobites to the Pleistocene proboscideans. the exhibition is rather small and labels and boards are far from being techincal, but fossil enthusiasts won't be disappointed, at least I was not! So tha's it, Let me know your impressions!
  10. Hello everybody! This summer I spent a couple weeks in the U.S. and besides the famous museums (Smithsonian, Carnegie), I enjoyed a few less knwon destinations. I want to start with the Orton Geological Museum, that exhibits the geological collections of The Ohio State University, in Columbus, Ohio. In the hall you are welcomed by a reconstruction of "Cryolophosaurus ellioti", a Jurassic Theropod found in Antarctica by a geologist of the O.S.U. you can see a reconstruction of the skull in the museum itself. Fossils are given the most space. I found very interesting the cases exhibiting the local fossils of Ohio, ranging from the Ordovician to the Pleistocene. the Ordovician case featured trilobites, brachiopods, nautiloids, bryozoans and other clades. the carboniferous featured also plant fossils. the Pleistocene specimens were Mastodon teeth and other bones. Besides this, a case showing the latest acquisitions kept a very large and well preserved Isotelus trilobite, the state fossil of Ohio. another case displayed fossils from the notorious Jurassic lagerstatten of Solnhofen, Germany. Other highlights were a reconstructed skeleton of a Megalonyx found in Ohio and of a Glyptodon from Argentina. Overall I found the museum really intriguing, because it displayed both fossils from nearby location and from all over the world. the museum layout is a bit aged, but it does not prevent having fun! Don't forget to visit the adjoining library, where a few large specimens are kept (including a slab with two set of prints made by a Carboniferous amphibian). I hope I was clear enough. let me know if any of you has already paid a visit here of you are now intrigued to! Thanks, Fabio
  11. I’m brand new at this. Please help.

    I found these on the shore of Lake Erie, on Catawba island (west of Cleveland, Ohio). Any help identifying would be greatly appreciated. Pic 1, the creature is about the size of a fly or ladybug. Pic 2 &3 are the same fossil and the rock is about the size of a baseball. Pic 4 & 5, the rock is about the size of a golf ball or an egg.
  12. Possible agatized dinosaur bone

    I found this today in a stream bed. It doesn’t look like just a rock to me. Seems to resemble bone with tissue. Any help in identification would be greatly appreciated
  13. Two More Paulding Ohio Finds

    I found these at the Paulding Fossil Park. I originally dismissed one as a horn coral as they are plentiful there. On closer examination it doesn't fit the typical growth pattern of a horn coral, no cone shape, no growth rings around the circumference. It is 1-3/4" in length. Could it possibly be a tooth? The spike shaped item is 2" long.
  14. Trammel Fossil Park

    Anyone here familiar with Trammel Fossil Park? I am in Dayton and I am going to be hitting a few places tomorrow. I want to go to Trammel first thing in the AM, but I can't find a ton of information on it online. My main question is what type of collecting is allowed? I have all my gear with me, 8lb. sledge, 5' & 3' prybars, chisels, etc. I don't have any power tools. Am I allowed to go to town there, or is that frowned upon? Thanks in advance for any info! -J
  15. Not sure what this is

    Found this guy in a creek in Cincinnati Ohio. Not sure what to think of it, we have a plethora of Ordovician fossils in our area, maybe it’s one of them. Kind of resembles a section of vertebrae to me but I can’t tell for sure. Would appreciate any help. Sample is roughly 3 inches long by 1.75 inches wide.
  16. Why Does the U.S. Army Own So Many Fossils?

    Why Does the U.S. Army Own So Many Fossils? Turns out massive flood control projects are a great way to find dinosaurs. by Sabrina Imbler, Atlas Obscura, August 7, 2019 https://www.atlasobscura.com/articles/why-does-the-army-own-dinosaurs Yours, Paul H.
  17. Unearthing prehistoric prizes at Sylvania's Fossil Park By Dan Smith, Channel 13 News, Jul 29, 2019 https://www.13abc.com/content/news/Unearthing-prehistoric-prizes-at-Sylvanias-Fossil-Park-513352581.html Yours, Paul H.
  18. Paulding, OH (Dev.) 7/28/19

    Found the usual goodies at Paulding today. But I'll only show this photo of a nice, thick chunk of Placoderm armor. This is embedded in hard limestone, so I think it's from the underlying Dundee Limestone Fm., rather than the Silica Shale Fm. (For those unfamiliar with the Paulding Locality, these are quarry dump piles). This is one of two placoderm pieces I found today. The color alone makes this a desirable find, let alone the cool factor of what it is.
  19. Not a huge piece of my collection but still neat. The fine details of these marine animals are often lost to the ages but every once in awhile you find a few pieces that catch your eye. I was digging through my collections curious about those fossils I found when I first started collecting. Came across this little invertebrate nugget. It is worn but the color and how it hugged the matrix was attractive. Taxonomy: Animalia; Bryozoa; Ectoprocta; Gymnolaemata; Trepostomata; Amalgamata; Monticuliporidae
  20. I have found what I believe could be a fossilized bone. Can I get confirmation on this? It was found in a creek in Holmes county Ohio. A book of my buddies says bison fossils are in the county.
  21. Beach fiindings

    Found these on the beach in Lorain OH. Not sure what they can be. Any help?
  22. Hello,

    Not sure what this is? Some type of fossilized coral?found on beach of Lake Erie, Lorain OH.
