  1. Monday morning was dreary here in Central Kentucky. The sky was cloudy grey, and the rain was sputtering off and on. I didn't let that dampen my spirits though. I had planned to go fossil hunting and nothing was going to ruin my day! I grabbed my hunting gear, a cup of coffee, dropped my daughter off at daycare, and headed out. I arrived at the Upper Ordovician (Drakes Formation) spot that I had found this year. The last time I visited this place I didn't have time to really enjoy myself. It was more of a smash and grab. A rush to see if anything was actually there and to grab what I could. This time I was determined to spend more time at my new found hunting grounds. Not even a little wind and rain would stop me. After about a 45 minute drive I arrived at the road cut. The last time I visited, I looked through the scree at the base of the cut and found items that, over time, had washed down from the rain. Many of these pieces didn't fair well with the 5-6 meter drop. After a few minutes of looking at the strata of the cut, I determined that the most fossiliferous layers were at the top 2 meters or so. I decided that I needed to check out the top instead of the bottom. I'm glad I did! After a short walk and hike up the gentlest slope I could find, I made it to the top. This is what I found. A loose layer of dirt (well mud since it was raining...) with coral heads and fragments everywhere! All different shapes and sizes. whole specimens just a few cm across to ones that where half a meter or more.
  2. Unknown critter from Ellisburg, NY

    I found this while fossil hunting in a creek near Lake Ontario in NY. It is Ordovician in age and I believe it is from the Trenton group.
  3. Orthoconic Nautiloid?

    I made a trip to my new favorite Upper Ordovician (Drakes Formation) spot today (working on a field trip report ). I came across a few of these cylinders, which I believe are orthoconic nautiloids. I found them in many different sizes. Some taper as I would expect from an orthocone. However, they do not have the suture lines or septa that I am used to seeing. Some have what appears to be a possible siphuncle in the center while others do not. Here are a few pics of some of the more interesting ones. I can provide more if needed. Thoughts? Thanks in advance for any assistance! This one is about 3cm in diameter and 7.5 cm length. Number 8 in first pic. There are also a couple that have this twisting pattern on the outside. This one is about 5cm in diameter and 3.5 in length. Number 4 in first pic. Possible Siphuncle? 1 cm in diameter. Number 7.
  4. I am considering buying this fossil offered online but it's NOT on our "favorite" auction site- just straightforward purchases. I really like this, and it's not QUITE up to what is not affordable for me. It is offered as an arthropod trackway in hyporelief.

  7. For your viewing pleasure. Sharing with the group.
  8. 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
  9. Missouri trilobite

    Need help on the id of this early ordovician trilobite butt. South Central Missouri.
  10. A few Ordovician unknowns

    Here are a few fossils I recently collected from the Maquoketa Group (Upper Ordovician) in northern Illinois that I'm not sure about. 1) Maybe some kind of trace fossil? 2) The two things in question here are to the left and right of the pentagonal crinoid columnal. The small fossil on the left looks like it might be part of a trilobite genal spine? And the three-pointed fossil to the bottom right I have no idea about. I feel like I've seen something similar before but can't remember.
  11. Fezouata Hyolithid?

    I am hoping someone on the forum might be familiar with Ordovician aged fossils from Fezouata. I believe this might be a large hyolithid but am not sure.
  12. Another odd one

    Another odd one! It's the same kind of surface I've found before, tiny spikes and bumps, and the previous one was suggested as some kind of lichid.
  13. Streetsville reconnaisance

    I hunted in Juan Emmanuel's old haunts. Went to Streetsville just for a reconnaisance. I didn't know the best places along the Credit River. So I went to a ball park between the river and Queen Street and just walked over to the water. The rocks scattered on the shore were just plastered with fossils...right where people picnic and entertain their children. Admittedly, most were of interest only to a beginner: Shell fragments, Bryozoan "wishbones", etc. Nonetheless, I had a good time and couldn't resist dragging some rocks home. Got a tetradium and a few nice corals, as well as other things to be identified.
  14. Fezouata Endless Fossil's Identification

    Hello dear fellows, Any ideas about this one from Fezouata Shale? It has 2,8 x 2,0 cm. A Brachiopod, a Hyolith, a Chrondrophore, a Clam??? Thanks in advance.
  15. Trilobite?

    This is my third and final request for an ID today!!! I lean towards this being a trilobite. If there is doubt, I will use a hammer to help expose this. If it is likely a trilobite, I will work on it in a little less physical way. It was collected 2 weeks ago in SW Wisconsin, Platteville Formation, Ordovician. Mike
  16. Ordovician ID

    On Sunday I went to a road cut in Ogle County, Illinois that exposes the Middle Ordovician, Platteville Group / Miffin member fossils. The below piece is something that I am having trouble identifying. Per @minnbuckeye request, I hope that these pictures are better. Any help with an ID would be appreciated.
  17. Trilobite ID

    I found it near Byron, IL. Can see gabella.... I need confirmation. My guess is gabricersurus....?!?
  18. 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.
  19. Hi all, It's been a while since I posted a trip report but I was feeling like posting last evening as well as testing out my new photography rig. I moved houses two years ago and lost my lovely brick wall backdrop (the exterior of back of the house) which allowed photography in natural light. The new house is all vinyl siding outside and I have more shade so less opportunity for good sunlit pictures. However, one corner inside the house has a bricked area where a wood burning stove used to be so I have decided to set up some lights there. The pics came out ok so let's proceed with the report. I recently went up to the St. Mary's quarry in Bowmanville, Ontario on a scheduled trip with the local Scarborough club and also stopped off at Arkona while in Canada. I did pretty well at Arkona where I found four Eldredgeops trilobites and two Blastoids among other finds. Nucelocrinus elegans from the Hungry Hollow member of the Widder formation. Sorry, no pics of the Trilobites due to some back spasms but I got these pics of a nice Atactotoechus fruiticosus branch also from the Hungry Hollow Member of the Widder formation. Then I went to the St. Mary's quarry on Sunday where I took a tumble down the rock pile and hurt my ribs. Lucky for me my hard hat took the brunt of the impact my head made with the rocks. With nothing broken and still able to move around, I stayed closer to the ground and found this partial, eroded Isoltelus sp. that is inverted and still shows the Hypostome in place. I also found a plate with Graptolites but that was too heavy to hold and photograph last night. I'll post it tomorrow maybe. Finally, I drove home on Monday and stopped off at a place in New York where some of the Kashong Shale member of the Moscow formation is exposed and found these two surprises. A cephalon of a Dipleura dekayi with some of the shell material eroded away. I think the eye is intact and waiting to see again once some rock is removed. And here is a closeup of the shell on top where you can see the stippled pattern where sensory pits used to be. Lastly I found a pygidium that I am not sure of the genera on. Possibly a Basidechenella sp.? So not a bad trip at all, despite the injury. Good news is that I am healing nicely but still have some soreness and muscle spasms. I'm looking forward to my next trip up in the spring and hopefully will avoid the health scares.
  20. Since there was no Fossil Garage Sale this weekend I decided to drive 4 1/2 hours down to Brookville and St. Leon, Indiana on Friday to do a little collecting at both sites and then headed back home on Saturday week. I was a quick trip and I hit both sites on each day. On Friday it was about 70 degrees, but poured in the afternoon while I was at a Brookville road cut and on Saturday morning it was a brisk 37 degrees and I forgot to check the "Feels like" temp. The cut is very steep and prior to the rain it was very dry and there were numerous times when I lost my fitting and slid down at least 5 feet each time. This was the first time that I had visited this site and I was reminded of it by @stats Rich when I saw him last week at the garage sale, though I did not go to the cut that he goes too. With this report I am going to keep it short and just show a couple of my finds, but I did find a lot of stuff. I found a lot of larger, loose Rafinesquina, and I believe that this is one, but I never have found one shaped like this big boy. I found a lot of Cyclonema snails and as many that were just the internal mold, some are pictured in the Right side pic. The top internal mold in the below picture is a Monoplacophoran. I think that I found about 20 Ambonychia pelecypods, here are some below. Here is a piece with an Ambonychia (Top Left) and a Caritodens (Bottom Right) pelecypods. I found several other pieces of Caritodens,here is one below. I only found 1 partial trilobite at the Brookville site. I found a number of loose Leptaena brachiopods and a few plates with many. I found several Vinlandostrophia brachiopods. I thinks that these are all Hebertella, but I could be wrong, there are so many brachs that look the same to me. Ans I found a few cool hash plates, here is one below. At St. Leon I only found 3 very small Flexicalymene trilobites, here is one below. I found this large piece of an Isotelus trilobite. Post to cont-
  21. Fall Break Fossil Trips

    The next few days are fall break for me, so I'm home from school. I decided to take the day today to explore two sites in Northern Illinois. The first is an outcrop of the Upper Ordovician Maquoketa Group in Kendall County, IL. I learned about this site from a recent trip report posted here, and found it after a little detective work. I was hoping to find Tentaculites oswegoensis, a small conical fossil of unknown affinities which is only found in this area. It only took me a few minutes before I found a few. I only stayed for 20 minutes or so, as Tentaculites is really the only well preserved fossil in these exposures. There were some brachiopod and bryozoan fragments, but nothing noteworthy.
  22. Thaleops? Cephalon?

    Found this one in Bowmanville (Mid Ordovician, Cobourg? Formation) last weekend. My best guess is Thaleops laurentiana cephalon but id like to have a better idea what it is before I attempt any more prep. Have not tried yet but probing with air abrasion looks like it will be difficult since the matrix is full of calcite or some other crystals. @Malcolmt @Kane @Northern Sharks
  23. Ordovician Hunt

    Last weekend I made the four hour trip to a spot I prospected back in July, exposing the upper Cobourg Fm near Nottawasaga Bay. The exposure was quite long with a maximum strata height of about 3 metres. Unfortunately, for all the travel and expense, no fabulous finds. The exposure is extremely weathered, and splitting mostly revealed tiny bits or blank muddy/chunky bedding. Still, I collected a flat of items that our local collectors would consider junk, but will make their way into the collections of other more farflung forum members at collecting meet-ups who do not get to collect up here. First up, Isotelus fragments which dominated the rock as very small bits, but occasionally larger partials appeared. The second image is of the wide pygidium with a free-standing section showing the doublure.
