  1. Cute Little Crinoid

    Got tired of prepping cystoids this morning so took a quick diversion to prep this little guy found on Sunday April 12, 2015 in the verulam formation near Lake Simcoe. Total length about 75 mm with a 10 mm calyx. Prepped under a scope with low PSI dolomite .010 nozzle, prep time about 20 minutes. Matrix was a crumbly shale which was field stabilized with cyanoacrylate. I believe it to be a praecupulocrinus but then again I am not the crinoid expert by any means so please jump in.....
  2. Unknown Ordovician Verulam

    Here is one for you knowledgeable folks. The fossil does not actually belong to me .The individual who found this specimen is a very experienced collector and has never seen this one before in either the verulam or the BobCaygeon. It was found last season in either the bottom of the verulam formation or the top of the BobCaygeon Ordovician formation near Brechin, Ontario Canada. We are generally calling this a cystoid or a crinoid. Some thoughts so far are (in order of our thinking) Balacrinus sp archeocrinus lacunosus Neoarcheocrinus Rare cystite Jump in with your thoughts
  3. Isotelus maximus molt

    From the album Urban Fossils of Toronto (Georgian Bay Formation, Lower Member)

    Isotelus maximus (Locke, 1838). Big trilobite pygidium molt and the only partial big molt I have ever found at Mimico creek. Approximately 15 centimetres across. Found in Mimico creek, Toronto, Ontario. Georgian Bay formation, late Ordovician. I found this by accident when I first started fossil hunting at Mimico creek back in October 2013. Shale specimen.

  4. So basically I'm planning on starting my journey of fossil hunting, but I have no idea what to look for. I live beside an inactive Quarry that I don't believe has ever been picked through for fossils before so it is an ideal place to start. I was just wondering if maybe you guys could post photos of things that I should keep an eye out for? So i can familiarize myself with different types of fossils. I will obviously know a fish when I see one but I also don't want to miss our on the small stuff due to my ignorance. I live outside of Ottawa in a rural area, so anyone who is familiar with this location would be a great help! I posted these in another topic but for anyone who hasn't seen them this is the quarry I will be going to. I want you to treat me as if i'm your child going hunting for the first time!
  5. Three Little Flexis

    From the album Urban Fossils of Toronto (Georgian Bay Formation, Lower Member)

    The unprepared and complete Flexicalymene granulosa trilobites all together from Mimico creek, Toronto, Ontario, Canada. Late Ordovician, Georgian Bay formation. All three were found in shale but I also found a complete one once on a limestone.

  6. Cyrtolites ornatus

    From the album Urban Fossils of Toronto (Georgian Bay Formation, Lower Member)

    Cyrtolites ornatus (Conrad, 1838). Late Ordovician monoplacophoran from Mimico creek, Toronto, Ontario. Georgian Bay formation. This one is set on limestone.

  7. Take 2 of the Modiolopsis slab

    From the album Urban Fossils of Toronto (Georgian Bay Formation, Lower Member)

    A second and more detailed photo of the modiolopsis slab. This one shows a little bit more detail, hopefully. Also, it appears that this thing is not full of modiolopsis as I first concluded, but rather it is full of Whiteavesia pholadiformis. There is also a Cymatonota lenoir, and it appears to me that there is only one specimen of modiolopsis, which would be M. concentrica. Dime shown for scale, and Georgian Bay formation, Mimico creek.

  8. Mucrospirifer

    From the album Arkona material

    The other mucrospirifer I bought along with the previous specimen I mentioned. Devonian stuff doesn't really interest me but with these I can feel a different surge of interest surfacing in me...I mean these Devonian fossils ARE kinda beautiful so why wouldn't anyone want them? Arkona, Ontario, Devonian.

  9. Complete Treptoceras crebiseptum

    From the album Urban Fossils of Toronto (Georgian Bay Formation, Lower Member)

    Complete specimen of a late Ordovician cephalopod Treptoceras crebiseptum, even with the living chamber intact. The length is appr. 37 cm. From the Mimico creek, Georgian Bay formation, Ontario. Specimen found in shale and my first complete one!! I usually find small fragments of the phragmocone at Mimico creek. Also keep in mind specimens found in shale are preserved squashed, compared to the ones preserved in limestone they are preserved in their original shape.

  10. Zygospira erratica

    From the album Urban Fossils of Toronto (Georgian Bay Formation, Lower Member)

    Zygospira erratica. These two are set on a limestone hash plate with an orthocone to the left. Both are the same species and have an obvious sulcus. Mimico creek, Toronto, late Ordovician, Georgian Bay formation. Edit: I also have found a massive slab of limestone that had a death assemblage of these brachiopods . I forgot to take photos though , and I'm not sure if the slab is still there.

  11. Late Ordovician Trace Fossil

    Is this trace fossil a rusophycus or something else? I also wonder what animal could've made it because I doubt it that any trilobite could have made it. Late Ordovician, Georgian Bay formation, Mimico creek, Toronto, Ontario.
  12. 'bivalvia Cliff ', Mimico Creek

    I made two trips to a place at Mimico creek where a cliff of bedrock collapsed recently and ended up exposing a good amount of fossils. The first trip was on this Wednesday and the other was on today. I mostly found Ordovician bivalves to spice up collection, because my collection lacked pelycopods. The recent rains here in Toronto were the reasons why the bedrock cliff collapsed. And I have to say, the debris that fell was productive!! I ended nicknaming the spot 'Bivalvia Cliff '.
  13. Humber River Area Find

    I just wanna share this cuz I never found an endoceras this big before, which is kinda special and unique for me . I was out fossil hunting at the Humber river area here in Toronto with a good exposure back on Saturday and I came across this big phragmocone part sticking out of the bedrock. It was tiring having to dig it out. Siphuncle sticking out Dug out.
  14. Flexicalymene granulosa

    From the album Urban Fossils of Toronto (Georgian Bay Formation, Lower Member)

    Flexicalymene granulosa, Mimico creek, Toronto, Ontario. Georgian Bay formation, late Ordovician. Complete specimen still embedded in the shale. Will need prep work to be exposed. I found this one at a collapsed cliff of shale at Mimico creek. I found some flexi's this summer at Mimico creek but usually whole specimens start crumbling apart the moment I try removing the matrix around the specimens.

  15. Whitella sp.

    From the album Urban Fossils of Toronto (Georgian Bay Formation, Lower Member)

    Modiolopsis ovata Whitella sp. found at Mimico creek. Internal mold of a clam valve. I picked this up from the bottom of a collapsed cliff. Georgian Bay formation, late Ordovician, Toronto, Mimico creek. I put a dime next to it for size.

  16. Ordovician Brachiopods Unknown

    These unidentifiable brachs have been bugging me for some time now. Any Ordovician collectors familiar with these?? Are these perhaps a species of Dalmanella? They come from Toronto, Georgian Bay Formation, late Ordovician.
  17. Modiolopsis Mayhem slab in situ

    From the album Urban Fossils of Toronto (Georgian Bay Formation, Lower Member)

    A slab full of late Ordovician fauna of the Georgian Bay Formation of Toronto, mostly containing whole complete Modiolopsis. Found at a collapsed cliff of shale at Mimico creek. Many specimens have crushed parts and their bits of crushed parts got thrown all over the slab, so probably this was a storm turbulence-caused death.

  18. Good day everyone, I found a fossil during the summer from the Williamsville Formation, Bertie Group in Fort Erie. I have had a few people take a look at it but have not had any luck identifying it. I was wondering if anyone might have any idea: 1 cm in diameter Almost perfectly circular Radial rings Can't see a verticle cross section Does not carry on to the bottom Photos are the only visible section THANK YOU
  19. It's embarassing, but I'm just now posting some pictures of the eurypterid fossils I came home with from my trip to the Stevensville Quarry in Ontario last August. It was an amazing day, and my first "splitting rocks" type of fossil outing. Althought I think I hit my hand with the hammer more than I hit my chisiel, I had such fun! Many thanks to Malcolm who showed me what to do, and where to be, and provided some great company in the hot August sun. Is there any way to tell the precise species of eurypterid these pieces came from? A more complete eurypterid piece that Malcolm gave me. I did my best to reconstruct its original shape with some clay. Malcolm told me that these 2 were fossils of a sort of plant, but I did not have the presense of mind to write the name down while we were out in the quarry (I was certain I would remember the names in my memory! nope) I can't wait to go back to Stevensville, maybe this spring!
  20. I live here in Toronto where I often hunt along this nearby creek and see, there are numerous amounts of worm trace fossils everywhere when I go hunting there. I find it so overwhelming to chose which trace fossil I should take home and there are so many of them!! I feel tempted to horde all of it, but that's not what i wanna do. I always wanted to bring home an interesting specimen, but I have no idea what I should look for that makes it interesting......... Do you guys have any good ideas as to what I should look for??? XI Btw the bedrock of the creek is Ordovician in age.
  21. I just thought I would upload a picture of a very large doublure that I have been prepping from St. Mary's cement quarry in Bowmanville Ontario, Canada. This is a fairly well recognized site that has produced some amazing specimens over the years. Unfortunately for us collectors they only open it up to us one day per year, generally in October. There were at least 4 of us from the forum there this year. I did find a number of relatively complete isotelus that day but in hindsight I think this is likely the only piece that will stay in my own collection. (Pirahna, if you are reading this and have any good article on isotelus doublure, they would be greatly appreciated. I have been trying to find a good picture or diagram of a complete one from isotelus.) The picture is an incomplete doublure from an isotelus latus. (originally I had thought I. gigas but Kevin has pointed out what I think is a better identification) The doublure extends around the underside outer margin of the cephalon and is visible in the ventral view of a trilobite. In some trilobites the hypostome is attached to the doublure to provide structural stability to the feeding apparatus. What you can see is approximately 170 mm wide or about 7 inches, that's a Canadian quarter by the way which is basically the same size as a US one. Based on this I would estimate the minimum length of the trilo to be 12 inches perhaps even a bit bigger. You can see the terracing on the bottom surface quite clearly. The piece is not completely prepped at this point as I still need to clean up the tool marks. Prepping was via airscribe and dolomite air abrasion. Here is a link to a good paper on isotelus hypostomes http://www.academia.edu/213012/The_function_of_forks_Isotelus-type_hypostomes_and_trilobite_feeding
  22. I must admit that ceraurus is one of my very favorite trilobites. I have been hunting diligently to try to find a prone museum quality specimen for my personal collection. This is the best that I have been able to find so far (I have about 5 others that are all in the neighborhood of 80% complete). Although this is not shown in the pictures there is a perfect hypostome that I have exposed on the bottom of the specimen. On the plus side it is very inflated and 3 dimensional with no squashing.The area that I am hunting for these is very fragile shale that has only been recently exposed and it is not standing up to rain very well. I found this one about four weeks ago. Not quite there yet for my perfect specimen but still not too shabby. What was particularly interesting about this one was that only 3 pleural arches were visible on the matrix and the rest was buried. I actually thought that I had found a flexicalymene which is the most common fossil at that location. The shale that it is in has been exposed to rain and is quite fragile. before starting the prep I soaked it in a very dilute solution of PVA (poly vinyl acetate) and acetone). This acted to consolidate the matrix. As I prepped I used a hypodermic needle to infuse more PVA solution as the exoskeleton had cracks in it and was prone to want to flake off. The prepping was done under a zoom scope using 44 micron dolomite air abrasion at a low PSI (18) and small nozzle size (.018 inches) There is still about 20 to 30 minutes of prepping to go before it is finished. I'll wait for my perfect specimen before entering one in fossil of the month..... lol...... I think I have the species correct but if you disagree with my identification please jump in... Ceraurus globulobatus Veralum formation Brechin , Ontario, Canada 1.8 inches long (47 mm) 1.4 inches wide (37 mm) I had the pleasure of meeting up with Crinus and Northern Sharks from the forum this weekend at the site where this was found. Turned out to be an absolute miserable cold rainy day. I arrived at the site about 8:00 AM and stayed till about 2:30 and it rained constantly the whole time I was there. I did however manage to find a crinoid calyx with arms (no stem), 4 enrolled flexicalymene and 4 enrolled isotelus , all complete. This season I seem to be finding mostly enrolled isotelus. I have only found 3 complete prone isotelus this summer. I had not posted anything in a while so I hope you enjoyed, I think you were all getting tired of my eurypterid posts.... I have found some amazing isotelus this summer, I really need to get my act together and prep them and take some pictures....... stay tuned..........
  23. Well I spent a wonderful day (perfect weather , not too hot not too cold and no rain) at the Eurypterid quarry today with two fellow collectors from the US and Quarryman Dave from the forum here. I was supposed to be hosting a member of the forum and his girl friend but unfortunately they had to cancel at the last minute. Too bad they might have had a very productive day based on how many eurypterids were found today.. One of the collectors from the US (he is a regular comes up about once a month) found a lovely 6 inch eurpterid with both paddles 1 walking leg and a balancing leg unfortunately the telson (bottom spine of tail) was missing. Non the less a great specimen. Note to self... he found it in a pit I abandoned a few weeks ago about 6 inches from where I was digging. He found it one layer below the layer I had been finding them in. Unfortunately, Quarryman Dave as hard as he tried just doesn't quite seem to have the knack for getting the eurypterids to bite for him. He actually split a lot of rock today............... Maybe he is using the wrong bait...... Not a total loss though he did get a very good geology lesson from a real expert and he found a partial head of a horseshoe crab. I have not found even a part of a horseshoe crab yet. (they are quite small only a a couple inches long at this location). While Dave was there I found this double plate that has a complete ventral view eurypterid at the top although the head is detached and positioned just above the body. The second eurypterid below the first one is a dorsal view and it is also missing the telson but on closer inspection the telson from it is up to the left of the top eurypterid (the one there anyway is the correct size for this one. The first one has its telson attached.. Dave is going to be ##### at me, I found two more complete after he left. He could only stay till about 1:30. The first one is about 7 inches long. I do not have a picture at this point it came out in about a dozen pieces and will require some intensive care. I will have the superglue out for sure tommorow. The 4rth one of the day is a real gem. Actually it is kind of amazing that I even saw it. It may turn out to be may favorite eurypterid that I have collected , haven't quite decided yet. For sure it is staying in my collection. It is the smallest eurypterid I have ever seen come out of the Williamsville "A" layer of the Bertie waterlime. Here are two pictures of the positive and negative with an american dime as a point of reference. This one is smaller than the tiny ones Pleecan and I sometimes find in the Fiddlers Green formation. All in all a very good day I would say (4 eurypterids) Mike and D. it was a real shame you could not make it. The offer to join me for a day of eurypterid collecting is open anytime you can reschedule. For that matter if anyone from the forum wants join me for a day just PM me. Just know there are days that we go home skunked. Just ask Quarryman Dave who has yet to find one in quite a number of visits or Pleecan.

  25. Ontario And Some Petrified Wood?

    Hello, I guess I'm not really sure what kind of info I can get from this, but I was hoping to determine what location this specimen might have been collected... I picked this specimen of petrified wood up at a pawn shop in Guelph. The employee said it had been in the shop for over 12 years, and the tag said 'found in Guelph, Ontario'. Whether this is accurate or not I don't know and I can't seem to find anything similar to it. It appears there are even 'sap' deposits that mineralized differently than the rest and there is significant crystallization over the whole surface of the specimen. Any information or direction would be greatly appreciated. Side A: Side B: Thanks!
