  1. 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.
  2. 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.
  3. 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
  4. 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.
  5. Trilobite ID

    I found it near Byron, IL. Can see gabella.... I need confirmation. My guess is gabricersurus....?!?
  6. 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.
  7. 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.
  8. 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.

  9. 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.
  10. 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
  11. 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.

  13. Predation on Trilobite pygidium?

    I recently found this trilobite tail with a piece missing out of it on both positive and negative sides. Could it be a bite mark?
  14. Lots of ordinary things lately at Etobicoke Creek and Joshua Creek. Of course, when I began hunting in April 2019, I couldn't imagine finding such treasures, but there you have it. At the former location, we seem to have fun finding "How many decent-size orthocone nautiloids can fit on one rock," and the number appears to be 10 or 12 in some cases ! We also seem to be able to find snakes when we lift rocks, which can be disconcerting. Recently I noticed some unpromising "wavy surface" rocks, but they had a layer underneath with branching bryozoan fragments. Turns out, there are lots of them, and some are the largest chunks I've ever seen. So today I was out in the rain, getting muddy. I had to leave lots of great rocks...they were reasonably heavy chunks. Tree roots along the creek had split up the shales, pushed some promising rocks through to the forest floor, and dumped lots of slabs onto the creekbank. When I get some of these rocks cleaned up, I hope to post some pictures. Meanwhile, here is a group of recent finds.
  15. I found this in ordovician strata that is approximately 450 million years old. It looks like a shell fragment from a bivalve or brachiopod, but it has rounded edges. Any help would be appreciated.
  16. Unknown Ordovician fossil?

    I found this back in July from the Ordovician Platteville Formation in Oregon, IL. This is the only picture I have of it, and unfortunately, since it’s at home and I’m at school, this is the only picture of it that I have. It’s less than 2cm from side to side. I just don’t know with this one, my best guess is part of trilobite maybe? Any help would be appreciated. Thanks!
  17. My wife and I went for an afternoon drive Saturday to see if we could find a few places I had been reading about a couple hours away. The first stop was Mcintyre Mountain, a Pennsylvanian plant fossil location looking through the tailings from a large but long abandoned mine town, like 150 years abandoned. The drive in was a 4 mile dirt road up the mountain. Luckily for us the majority of it was well maintained and the scenery was beautiful.
  18. Hi all, I have been more or less away from the forum for the last few monthes. Life has been hectic. And if i still managed to go on the field quite a lot, i did have any time left for the rest (writing, taking photos, processing stuff, labelling etc). Nevertheless, i finally manage a quick photo session. As an appetizer, what is prolly the best piece for quite some time. A double trilo, Eodalmanitina sp, one preserved with his caudal spine. So 2 rocks as a starter . I had to sacrifice part of the 2 counterprints, to unveil the opposite trilo... Regards.
  19. Trilobite tail, or not?

    I found this Cryptolithus in the Late Ordovician, Viola Springs Formation of Carter County Oklahoma. Can someone tell me if it is C.fittsi which I see on a fauna list for the site or another species? I'm also wondering if the segmented strand below it is part of the tail or something else?
  20. I decided to leave at 5 am on Friday to head down to a roadcut that I read about that was located in Maysville, Kentucky. I knew that it was at the right off of AA Highway so I decided to grab a hotel in Wilder, Kentucky which seems to be the start of the roadcuts that are on AA Highway. After 5 hours of driving I was in Wilder and started down AA Highway knowing that I might stop at a couple roadcuts prior to hitting the big one in Maysville. Believe it or not, if you count all of the roadcuts that are on the 41 mile drive from Wilder to the turn off for Maysville you will pass, if my counting is correct 120 places to collect. Now I counted each side as a separate roadcut since sometimes I find different things on each side. This will be a picture heavy post since I stopped at Maysville twice, plus 8 other roadcuts on AA Highway and on the way home Sunday I spent about 5 hours at St. Leon, Indiana. I will be identifying the locations using the name that is associated with the pictures that I took with my I-Phone, not sure if the cities / towns are correct, but besides Maysville and St. Leon, all of the stops were on AA Highway. Stop 1 was at a roadcut in Melbourne, Kentucky. Like most of the places that collected at in Kentucky it has a heavy concentration of bryozoan, there were also trace fossils and Trilo-bits. Here are a couple pics of what can be found here. Trace Fossils- Hash plate with Flexicalymeme Trilo-bits- Bryozoans- Stop 2 was at another roadcut in Melbourne. This site I found the bivale Ambonychia. Bryozans- Hash plates with Hebertella brachiopods and Isotelus trilo-bits. Orthoconic nautiloids- Other Trilo-bits of Flexicalymene. Stop 2 Trace fossils to follow-
