  1. TriloBITS

    Hi! I stopped at a rock and fossil show earlier today and I picked up these trilobite parts along with a couple other more complete pieces. I was wondering if it is at all possible to ID it only with these parts. I’m thinking the large part is an Isotelus pygidium and the separate piece on the right looks like an eye, but I’m no expert. So if any of you have ideas, send ‘em at me! From Canada, Middle Ordovician, from Colborne Quarry in Colborne, Ontario
  2. Predation Marks on Hebertella?

    Hi guys so I have this Hebertella occidentalis specimen I collected yesterday from the Credit River at Streetsville, Mississauga, Ontario, which belongs to the Upper Member of the Georgian Bay Formation. Do these look like predation marks? There are also what appears to some crystallized grains inside these marks and I think they could be some sort of calcite. Sorry for the noisy grain of the image, but I hope this will help.
  3. Flexicalymene Mineus

    From the album Trilobites

    A nice little trilobite in a defense posture all rolled up. This Flexicalymene Mineus is a smaller but pretty cute little trilobite. Trilo is upper Ordovician in age, from Maysville, Kentucky. I will have to add in the measurement later on as I have forgotten.
  4. Ogyginus Corndensis

    From the album Trilobites

    A nice little trilobite I aquired from the United Kingdom. Ogyginus Corndensis, from the Landrindod Wells, Powys, Wales. Ordovician in age. Trilobite is about half an inch.
  5. Possible Huge Bryozoan/Anthozoan

    Hello all! I was hunting for fossils in Owingsville, KY on a road cut that contains the Drakes Formation (Late Ordovician). Plenty of brachiopods, small bryozoans, cephalopods and other common Ordovician fossils found. I happened upon this piece, at first just thinking it was geologic with some bryozoan encrusting/deposited within the rock. I almost left it behind but couldn't help but wonder if it was all one piece and that it may truly be an example of large bryozoan or coral. I was curious as to what you all think, whether it be one of the two, mostly geologic or what have you.
  6. Possible fossil found on walk

    I found this in Niagara Ontario, in Upper Ordovician/Lower Silurian rock. The rock is mainly crinoid limestone. I'm not sure if it's a fossil. I wish I had a measurement, but I found it by accident, and didn't have a ruler.
  7. Northeast Arkansas Ammonite?

    Two fossils from Northeast Arkansas southern ozarks.Found in shallow red clay wash.Possible ammonite or mabe gastropods I do not know?This area is not known for cephalopod fossils.Lower Ordovician? I would like to know what others thank. An ID would be great.Thanks.
  8. Today I was out collecting in Lawrenceburg, Indiana for several hours, accompanying me was some rainfall. This will be a picture heavy post and I will show various fossils that I found and many pieces that I left in the field. I will start out with trilobite parts of Flexicalymene and Isotelus. I did find my first ever complete trilobite, at least I think it is my first, and also my largest piece of an Isotelus that I have ever found. Now the pieces- Next post will be Bryozoan-
  9. Today I spent a little time in Lawrenceburg, Indiana Collecting some Ordovician fossils. Today I collected some brachiopods, bryozoan and trilo-bits. I usually do not collect much bryozoan, but I did like this piece. There is always a lot of bryozoan to be had— Here are some brachiopods that I collected- Here is a bunch of Trilo-bits, mostly Isotelus.
  10. Ordovician Creepy Crawler???

    Hey everyone! I was digging through a hash plate today and came across this figure within. I have yet to see anything with this shape yet. It may be nothing, and by all means call me a noob and idiot but I thought I would ask the experts On your thoughts. Plus I haven’t posted in awhile and I miss all of you! Hahaha
  11. Plattville Ordovician Unknown

    I had a fun weekend hunting for fossils. The first day was spent in East Central Iowa with the fossil club that I belong to. A special find occurred there (placoderm tooth) and identified on the forum yesterday. I then headed east and looked at the Ordovician Platteville of SW Wisconsin. While at home looking at the specimens I returned with, I stumbled across this. Has me baffled. A stem taking a right angle turn leading to a sunburst type of pattern up top. Probably a few different bryozoans that come together suggesting what I see. But I would like some more intelligent people than me to evaluate this and give me their opinion. Maybe, just maybe something special??? I will cross my fingers. Thanks for the opinions, Mike
  12. Yesterday the weather in my area hit above the 20 degrees Celsius so I dared myself to go to Streetsville in Mississauga to visit a fossil site I have not been to in 2 years. I now live in Hamilton, Ontario so travelling to Streetsville was intimidating for me using public transit from Hamilton to Streetsville. I have not been to Streetsville by the Credit River ever since I moved from Etobicoke to Hamilton, Ontario and I miss collecting in this vicinity. But I made it. :)) I took pics of exposure sites as these sites are mentioned in one of the literatures describing the Georgian Bay formation. This site exposes the Georgian Bay formation, Upper Member.
  13. Cephalopod Preparation

    Found this cephalopod at Caesar Creek a month ago, just now got the chance to clean it up now that school is done. It's about 4.5 inches long and 1.5 inches wide. My best guess at ID is Cameroceras but if anyone thinks it may be something else please let me know. Looking at about 450 million years old. Before After
  14. Early B-Day Gift

    When I got down to Georgia my wife had an early birthday gift for me. She always tries to get me things that are fossil, rock climbing or backpacking related. This time she said that she searched the Fossil Forum site and some member was talking about chisels, so she bought the ones below. These should be great when collecting my Ordovician or Pennsylvanian road cuts.
  15. Trilobite Hunt in NSW

    G'day everyone! I have reccently come back from a three day trip to Forbes with the Australian Fossil Club where we looked for Ordovician and Silurian trilobites. We checked out the Silurian Cotton Hill Quarry as well as some new Ordovician sites around the town of Gunningbland. Fellow forum member @Foozil was also apart of the trip. Over the three days I ended up with many beautiful trilobite fossils and my first whole specimens! @piranha could possibly help with IDs? DAY 1 - Cotton Hill Quarry Friday morning my dad and I left home at 3:30 AM and began the 7 and a half hour journey from Melbourne to Forbes in Central NSW. We arrived at the first site, Cotton Hill Quarry at around 12:30 and began digging. The fossils here come from the Cotton formation, approxomitely 435 million years old. The most common fossils at the site were bits of the Sinespinaspis markhami , a small odontopleurid trilobite. They were common fragmentary remains however whole ones were still uncommon to find. Unfortunately, the layer that the Australian Fossil Club used to dig was buried udner 1.5 metres worth of rock by the local council as they were looking to smoothen out the sides of the quarry and possibly revegetate most of the site. However we soon found the layer again and I found quite a few nice Sinespinaspis markhami. After 5 hours of digging, we went home and prepared for the next day ahead. The Quarry Sinespinaspis markhami
  16. This fossil is not like the other Gastropods I find in this creek. The shell is more inline instead of going out to one side.Very few Cephalopods found in this creek.Lower Ordovician Northeast Arkansas creek gravel.Southeast boundary of the ozark uplift.Someone Please ID this fossil.Thank you.
  17. Day Three ; Locality One (Or Eight if you include Days One and Two) Ait Benhaddou, Morocco. 21st February 2019 We spent the second night in Ouarzazate, where the biggest film studios in Africa can be found and many famous films have been shot. In the morning we went briefly to the Atlas Studios where Anouar took some photos of the exterior for his blog, but non of us actually wanted to go in, so we headed for the kasbah of Ait Benhaddou. The road going south from Ouarzazate, at Ait Saoun, just before one reaches Agdz is a fossilized and genuine stromatolite reef, but it was out of our way on this occasion, so that's one for another day, but here's a photo courtesy of the Universities Space Research Program who test out Moon Buggies, Mars Rovers and stuff there. Just before we reached Ait Benhaddou, we stopped off at a viewpoint, I wanted to look at the rocks and hillside as fossils can be found in this area. I can't remember what they were as i didn't find any, but one of the hills next to the kasbah is quite famous, so i'm told. You can see the kasbah in the distance here and i think the hill just to the right of it is the fossil location. Hunting around, I did find lots of pieces of what I think is a porphyritic gabbro. Nice phenocrysts!
  18. Isorthoceras sociale (Hall 1877)

    From the album Nautiloidea

    The plate measures 11x9x3cm. Elgin Member Maquoketa Formation Richmondian Late Ordovician Found at a roadcut near Graf, Iowa Gift from Minnbuckeye.
  19. Caesar Creek Fossils

    Hey all! I'm new to the forums and this is my first post so I figured I'd show off my recent finds. I'm just an 18 year old from Michigan and this was my very first time fossil hunting. Seeing as how there isn't good fossil sites in Michigan, the next best place to look would be Ohio, and luckily I live near the border. I had read different opinions of Caesar Creek and was skeptical of whether or not I would find some good fossils out there, but I decided to go since I had to start somewhere. My family of 5 went down there for the weekend and went to the spillway on Friday. Luckily, the freeze-thaw cycle had just ended and it rained over night. We figured this would be the best chance of the year to find some good fossils. We were the only people there all day and hunted for about 4 hours. With 5 people hunting we were able to find a good amount of fossils. We found a lot of brachiopods and bryozoans of course, and then towards the end we started finding more gastropods and horn corals. We were bummed that we hadn't found any trilobites all day when we finally found the sweet spot. About 10 different pieces of Flexicalymene and 3 of those being whole and enrolled. We were pretty stoked to be able to find those and some of them looked really nice. I realize they're just some basic Ordovician marine fossils but everyone has got to start somewhere and I'm happy with the collection I was able to start. Already planning a trip to Fossil Park in Sylvania for early May since it's just an hour from my house. And then looking to possibly go to Calvert Cliffs/Brownies Beach in Maryland during the summer to look for Miocene shark teeth and others in the Chesapeake. Let me know if you see anything wrong with any ID's, that'd be great but other than that enjoy these mediocre pictures I took.
  20. This fossil was found in Northeast Arkansas.Sandy wash.Lower Ordovician. This fossil may not be common in this area it's the only one I have ever found.Thanks.
  21. Backwards Gastropod?

    This species of Gastropod seems different than the other Ordovician Snails I have found.It appears to spiral backwards.Can someone name this species and is it common?
  22. Hello guys. I’ve got 2 Late Ordovician reef fossils from Streetsville, Mississauga, Ontario, Canada that I’d like to trade away to make room now that the fossil hunting season is coming back soon. I am trading away the specimens below. These are very nice specimens and comes from an exposure out of access to the ordinary public. Both belong to the Upper Member of the Georgian Bay Formation. Favistina calicina: Stromatocerium huronense:
  23. Advice on Prepping Limestone

    Hello everyone, I'm New to the fossil forum. I'm from Minnesota and I've got some nice sized Ordovician fossil from the Platteville formation in Rochester, Minnesota. They're in Limestone sediment. One is a slab that is a filled on both side with crinoid stems (hoping for other rarer parts under the sediment on this slab). The other two are large section on cephalopods. I'm looking for some advice/tips on how I should go about prepping them. Like what kind of tools should I be using and if I should use any chemicals. Any advice/tips would be appreciated. Still fairly new to fossil preparation. Also if better pics are needed I can get them Thank you
  24. Back in May 2017, I brought back some nice fossil plates from Ohio, I believe Ordovician in age. First photo is plate 1. Next photo (of plate 1) shows a close-up of parts of the trilobite Isotelus, next photo - a nautiloid (unknown species), next photo shows valves of the brachiopod Strophomera, along with many bryozoan fossils. Next photo is a close-up of crinoids on plate 3. (Not much on plate 2). And last photo is of quite a few crinoids on plate 4.
  25. Help me id mold fossil please

    Please bear with me as I am new to fossil identification. My 14 year old son recently became interested in fossils and geodes, so I am trying to encourage his interest. We found a round rock about the size of a bowling ball recently while digging to install a septic tank and he wanted to break it open to see if any crystals were inside. When he broke it open, he found some fossils, one of which I believe is called a mold fossil, images attached. The object that made the imprint appears to have had spines or thorns. Any help is appreciated! This was found in west central Missouri, SE Henry County. The imprint measures approximately 4-5 cm long. The round circle near the imprint appears to be a similar mold fossil, seen end-on. When he broke open the rock, he apparently split the mold down the middle. The pictures show both halves.
