  1. It was a beautiful 53 degree day today and I decided to take a 155 mile round trip to Oregon, Illinois. The purpose of the trip was to collect a road cut that exposes the Middle Ordovician, Platteville Group / Miffin member fossils. @connorp was nice enough to give me the location to this 1/2 mile collection site in Ogle County. I had fun checking out this area, but it will probably be my own time visiting this site and not for any particular reason. There is plenty places to park along the road, but this area can be tricky for people who are not sure-footed and children, as the scree on the hillside can move easily, there is also a deep drainage hole located towards the middle of the collecting area and some of the cliff face is unstable. SCREE- Drainage Hole- Unstable Walls- Here are some other pictures of the area. Fossils to follow in next post-
  2. What animal is this?

    Good morning everyone, Few weeks ago I found this interesting imprint in limestone erratic boulder, it was found in Klaipeda district Western Lithuania. The fossil is 2 cm length, I would think it belongs to worm or maybe sea cucumber. Any idea? Best Regards Domas
  3. Ordovician Tail?

    I found this several years ago in Kentucky near Maysville, which, based on this map, is in the middle to upper ordovician. It was probably around 50 feet down. All I have is the tail. Probably not enough to identify, but any information would be appreciated. I couldn't find a measuring device, but I will post a picture with one as soon as I do. It is about 8 1/2 inches long, or 26 1/2 centimeters. Map is upside down. I have the fossil on hand for any clarification/questions.
  4. Large ordovician tooth?

    First off, I don't know anything about paleontology. I found this fossil in Nicholas county Kentucky. It was about at the C in NiCholas county on the map. Sorry it's upside down, but Nicholas is 2 above bracken, assuming picture orientation. The fossil was 6-10 feet down. The first layer of fossils went down about 5 feet, maybe more, and we're tan and sandy. Below this layer was a gray layer, and this was several feet into that. Also, don't have enough file space to do enough pictures for inches, but it is about 11.5 centimeters long, or 4.53 inches.
  5. Nautiloid? Ordovician, NT, Australia

    Hello everyone! I've been examining a fossil I found a short while back and wanted to try and confirm my suspicions that it is a Orthoconic Nautiloid. Interested to hear some opinions from those more knowledgeable than I. So far I've been struggling to find good resources describing the different species found in this formation, it seems the work of John Laurie should possibly be my focus. The diameter of the possible siphuncle seems unusually large and positioned in very close proximity to the outer shell. I seem to remember reading something about the siphuncle moving closer to the outer shell as the nautiloid ages. The fossil was found in Maloney Creek, NT, Australia and comes from the Horn Valley Siltstone, early to middle Ordovician (487 Ma - 468 Ma). Feel free to ask for any additional photo angles, measurements or further information on the location. I also have a number of specimens from the same location that are clearly straight-shelled nautiloids, but likely another species.
  6. Decorah Group Trilobite

    Need help with identification of this trilobite cephalon from Silex, Missouri (Middle Ordovician, Decorah Group, Bloomsdale Fm?) I'm thinking Eomonorachus intermedius? @piranha @GerryK Scale in mm I also found this hypostome in the same spot. Not sure if it's the same taxon.
  7. What on Earth?

    Hi TTF! Since I am now going to present my science fair at the Ontario regionals, I have decided to add a few new displays to it. Right now, I am working on a model of the Earth during the middle Ordovician, when Pseudogygites Lantimarginatus lived. I have searched the internet for pictures of the middle Ordovician Earth, but each one is slightly different. For example, the location a Siberia changes with almost every map. I assume this is just because the different maps were made during different eras or by different people. Does anyone on the forum know which is the most up to date image? There are some images of the globe as it is right now below.
  8. BRACHIOPOD

    Rhynchonellids are hard to identify by exterior morphology as they often need to have their internal structures visible to be sure of an id. However if you know the faunal lists from a specific area, you can reduce the candidates considerably. The specimen here has 22 costae with 4 on the fold and thus, at this size must be one of two species, Rostricellula minnesotensis or Rhynchotrema wisconsinensis. The only completely safe way to differentiate between the two is the presence or absence of a cardinal process in the brachial valve but this is not possible here. However, Rostricellula usually, though not always, devoid of shell ornamentation, such as ridges or the presence of growth lines, and Rhynchotrema wisconsinensis usually, though not always, shows these, though they can also be seemingly absent through wear. But, R. wisconsinensis never shows a length to width ratio of 1.00, only from 0.80 to 0.95 and this specimen has a ratio of 1.00 which does occur in Rostricellula. Furthermore, the fold of Rostricellula is wider and less sharply developed Finally, good specimens of Rostricellula are far more common than R wisconsinense at the locality as the species most commonly found here is Rhynchotrema ainsiei which is describe elsewhere and not to be confused with the other two due to it's larger number of costae Thus, I am fairly confident with my id
  9. JUVENILE BRACHIOPOD

    As with the adult this has more costae than any other brachiopod found in this formation. In this case 32. and 5 of them on the fold. The fold and sulcus are not yet very noticeable, as this species only develops a noticeable fold as it matures.
  10. Orthocera group.JPG

    From the album MY FOSSIL Collection - Dpaul7

    Orthocera Specimens 11" x 18" Morocco Data: Orthoceras ("straight horn") is a genus of extinct nautiloid cephalopod endemic to Middle Ordovician-aged marine limestones of the Baltic States and Sweden. This genus is sometimes called Orthoceratites. Note it is sometimes misspelled as Orthocera, Orthocerus or Orthoceros (Sweet 1964:K222). Orthoceras was formerly thought to have had a worldwide distribution due to the genus' use as a wastebasket taxon for numerous species of conical-shelled nautiloids throughout the Paleozoic and Triassic. Now, Orthoceras sensu stricto refers to O. regulare, of Ordovician-aged Baltic Sea limestones of Sweden and neighboring areas. These are slender, elongate shells with the middle of the body chamber transversely constricted, and a subcentral orthochoanitic siphuncle. The surface is ornamented by a network of fine lirae (Sweet 1964:K224). Many other very similar species are included under the genus Michelinoceras. Orthoceras and related orthoconic nautiloid cephalopods are often confused with the superficially similar Baculites and related Cretaceous orthoconic ammonoids. Both are long and tubular in form, and both are common items for sale in rock shops (often under each other's names). Both lineages evidently evolved the tubular form independently of one another, and at different times in earth history. Orthoceras lived much earlier (Middle Ordovician) than Baculites (Late Cretaceous). The two types of fossils can be distinguished by many features, most obvious among which is the suture line: simple in Orthoceras, intricately foliated in Baculites and related forms. TIME PERIOD: Middle Ordovician (458-470 Million Years Ago) Kingdom: Animalia Phylum: Mollusca Class: Cephalopoda Order: †Orthocerida Family: †Orthoceratidae Genus: †Orthoceras
  11. Sorry this report is late, but I wanted to wait until prep was complete as I always show unprepped finds lol. Back in May, Laura and I made an impromptu trip to Grant County Wisconsin for some trilobite action. We had spent nearly five hours hunting with only partials and some hash plates uncovered. I decided to sit in the middle of the site and take a break and let Laura search. Being bored, I started to pick up pieces of rock and brush off the dirt and broken pieces of matrix. To my utter shock, I brushed off some dirt and saw a cephalon emerge, with what looked like thoracic segments. I finished brushing off the dirt and was in shock. My first complete Ceraurus mifflinensis (Demott1987). I was not prepared at all and my wife said I sounded like a five year old opening every Christmas present I've ever wanted. Well here she is, Gabi in all her beauty. It was truely amazing to be the first human to see such a magnificent creature. Prep was completed by David Comfort July 1st. Thank you @piranha for connecting me with the world renowned prep master. Now prepped
  12. Hi guys, This is my 1st post(Execpt introduction)! I went to fossil hunting at June 5th and 6th to Gangwon-Do, Republic of Korea(South Korea). It was my 2nd geological exploration. Location information : 1st site - Jangseong, Gangwon-Do, Republic of Korea(South Korea) = Jiggunsan Formation(Jigun Mountain Formation), Middle Ordovician <Figure 2> 2nd site - Sesong, Yeongwol-Gun, Republic of Korea(South Korea) = Jiggunsan Formation(Jigun Mountain Formation), Middle Ordovician <Figure 3, 4, 5> I rode a bike to get there about 110 km(Actually 50 km. Including returning distance is 110 km.) and there was a lot of bugs like flies or mosquitos etc. It was very hard journey but it was very nice too. This picture took at the first fossil site.(Actually, before arrive at the fossil site.) The first fossil site was easier to access than the second fossil site. \ Actually, I couldn't find the second fossil site. I heard that veeeeery many fossils are there(Trilobites, Cephalopods, Gastropods, etc.). However, it was too hard to get there. Forest was too thick to access! So, I couldn't find the actual fossil site, but I found a pile of black shale. Probably it exposed the tip of the formation or crumbled and moved from the site. Anyway, I didn't have much time at that time to investigate arround there. I hope to go there again in order to investigate someday! I collected 88 specimens there.(Except donation. I donated about 27 specimens to national museum.) I could find a lot of trilobites and gastopods. I couldn't find a complete one, but I found sub-complete trilobites and its eye lens are completely preserved. Also, I found complete ventral cephalon of trilobite. Its hypostome is very good conditon. I found this one at the 1st fossil site. And, I found a lot of trilobite hypostome at the 2nd fossil site too. Left side - Excavated at 2nd fossil site Middle side - Excavated at 1st fossil site Right side - Excavated at other fossil site. It's plant fossil. I found them in a pile of coal muck. It's Gangwon-Do too. * I'll update fossil images after this post. I resized whole, but I think that the data is not enough to upload whole images here.
  13. I bought this from a store in my area, it is labeled Licuites Iii. I think it's real but I'm weary, especially since there was a "Made in China" sticker on the back. If it is real, is the ID correct? on the bottom it appears that some fossils have been cut through, and on the end part of the orthocone there is a faint circle in the rock, suggesting it's three D. Assuming it's real, can it be prepped? Thanks for any information!
  14. Image of Reophax foram

    Ive been looking over some Platteville plates for a trade with a member, but I am having issues with finding access to some images or papers. The image or paper i'm looking for is on a middle ordovician foram, Reophax blackriveranus n. sp. thats found in the Platteville formation- Mifflin member. Papers on other forams found in this formation would also be appreciated. If anyone is able to assist, I would be grateful. Thanks! Best regards, Paul
  15. SW Wisconsin Hunt 9-11-2016

    My wife and I took a trip to Grant County here in Wisconsin on 9-11 as a tribute to the anniversary of the day that affected us all. We left around 6:30am-ish and arrived at our destination a little past 8am. It had been raining the past several days so our chances were good that slides had exposed new rock and washed away dirt from old. Upon inspection, the site looked fantastic, but the insects were out in full force. I began by just a quick walk around scouting and picking up pieces here and there; a few brachiopod plates and corals. Throughout the day we found many partials, but these were of specimens we did not currently have in our collection. I had intended to visit a few sites I had been to before. The site we were at was our first time there and the finds just kept coming so we stayed there the length of our hunt. Here are some pictures of the site and our trilobite finds. These were all found at one site in the span of 6 hours. I have tried to identify them the best I could so if I made an error feel free to correct me. Id rather have the correct name on the label than not. Mffln mbr-Platteville Formation Middle ordovician SW-Wisconsin Measurements are in centimeters Hermiarges aff. H.paulianus (Clark-1894)-Cephalon(On Right) Sceptaspis lincolnensis (Branson-1909)Pygidium(On left) Thaleops sp. With cephalopod and brachiopod association Ceraurinella templetoni n. sp. Amphilichas sp. Bumastoides milleri (Billings-1859) continued on next page...
  16. The following graptolites were collected at two Luster’s Gate locations east of Blacksburg, Virginia, one on VA 723 (UTM 17S 556351.49 4121426.16) and the other on VA 785 (most likely, UTM 17S 556851.28 4122155.54). I remember the second location as being just north of a sharp bend in the road and I wish Google Earth would run a street view down VA 785 so I could verify it. The locality on VA 785 has been listed as having exceptional preservation (lagerstatten) but I had never considered it so, until I found Specimen # 6. Anyways, I’ve photographed and scanned six specimens and I am having problems pinning down any type of assured ID other than graptolithina. I’m not well versed in graptolite taxonomy and I realize the preservation is somewhat poor, so I would expect speciation unlikely. But, maybe someone in the FF familiar with the taxa and/or the site can verify my lame attempt at taxanomic placement of some of the specimens and make a generic or family/group determination on all. That would be most helpful. Also, is anyone aware of where I might obtain a copy of the following thesis/dissertation other than the VPI library? J. Duval Shultz, 1919. The Graptolites of the Luster's Gate Locality, Montgomery County. Virginia Polytechnic Institute, 18p. Specimen#1 Specimen #2
  17. I see these every once in a while, but I can't seem to locate any information on them. The shape is fairly consistent involving a tapering "cone" with a bulbous end. I'm hoping with such a distinct shape, someone with knowledge of Byrozoa may be able to assist me with a possible genus or family. Middle Ordovician, Blackriverian (similar in age to the Bromide Formation of Oklahoma) Platteville Formation, Mifflin member Southwest Wisconsin All pictured measure around 3cm These are 3 different specimens on the same hash slab: Thanks, Caleb
