  1. Hi everyone! The last few times I went out fossil hunting, I tried to find new exposures along Mimico Creek in Toronto. All of these trips were unsuccessful, so I thought I'd try to find a new site along Etobicoke Creek instead. Today I checked out a new location and fossils were found - hooray!!! Here are some photos of what I found: (note that all of these fossils are from the Upper Ordovician Georgian Bay Formation) First, the trilobite pieces (@piranha - please let me know if I've identified them correctly - thank you! ): Isotelus maximus: cepha
  2. I am posting some pics of my trip to Etobicoke, Ontario on the Georgian Bay formation, Lower Member. I only went a couple times to different localities in Etobicoke since the lockdown put a strain on my wanted public transportation service. I visited the Humber River and Mimico Creek. I only came home with 2 specimens from the Humber while I didnt take anything home from Mimico. This year's winter has been mild so that is why I believe there has not been any turn around for [good/unusual/extraordinary] material. I recall back in 2015, which had a rough and severe winter, generated

    Is this pyrite disease?

    Hi guys I recently found this nice sized Pholadomorpha pholadoformis at the Humber River in Etobicoke, Ontario. It belongs to the Georgian Bay formation and is late Ordovician in age. The specimen has pyrite in addition to the black film. Does this fossil have some sort of pyrite disease to it?
  4. So I have been looking at my collection and it baffles me whether these two specimens are the same species with just different growth forms due to their deposition environments or are they entirely different species from each other? These stromatoporoids both come from the same locality (Streetsville, Mississauga, Ontario) in the Upper Member of the Georgian Bay formation, late Ordovician. Can anyone provide me with any PDF on late Ordovician stromatoporoids so I can nail down the differences between Stromatocerium and Labechhia? On the site where I collected these, I
  5. Hello to all! Hope everyone is doing well, cause after my recent finds I am definitely doing well . So a little backstory: 10 years ago in grade school when I used to collect fossils with my father, we would never find any good fossils in shale. Always layer upon layer of the bland gray rocks with nothing even close to a fossil. For the longest time I never even bothered glancing at the large sections of shale dotting the many rivers of Toronto. jump ahead to the beginning of the month when I read some posts from @JUAN EMMANUEL showing some very nice nautiloids from sh
  6. Hi everyone! I found this piece yesterday at my new spot along Etobicoke Creek here in Mississauga, Ontario (Georgian Bay Formation, Upper Ordovician). It's a bryozoan of some sort with some crinoid stems on it, along with an imprint that I think is either a Cruziana ichnofossil or a weathered crinoid stem imprint - what do you all think? I've boxed the imprint in red. Thanks in advance! Monica Views of the imprint: View of the other side of the rock/bryozoan: Close-up of the bryozoan:
  7. Hello once again! Upon closer examination of some items I recently collected from Etobicoke Creek in Mississauga, Ontario (Georgian Bay Formation, Upper Ordovician), I have found a couple of items I'd like your thoughts on. Item #1: Found on the same rock as a monoplacophoran (Cyrtolites ornatus), the unknown item is tucked underneath some matrix: View of the whole rock: Close-ups of the unknown item: Continued...
  8. Hello! I recently decide to split a fossil that seemed to have the edge of a shell poking out. To my surprise, it split open to reveal something I have never seen before in all my years hunting in Toronto. I thought perhaps it might have been the head of an unusual trilobite, but I am not convinced for sure. It was found on the riverside deposits of Etobicoke creek in Toronto, Canada, which is part of the Georgian Bay formation. Let me know what you guys think @Malcolmt @Monica @JUAN EMMANUEL:
  9. Oye I managed to get my hands on some very rare stuff (at least in terms of my local area) while hunting this last month in the Georgian Bay Formation in Toronto, Canada. Some of these fossils have been some of the nicest I've ever found, and will probably look even better with a little cleaning. Let's start things off with the usual nautiloids with a side of bivalves: Treptoceras crebriseptum I love these plates so much - they are currently some of my favourite fossils in my whole collection at the moment Treptoceras crebriseptum for the first th
  10. Hello all! So I've been looking through my collection and noticed a bunch of fossils that I haven't yet identified yet. Some of them are quite peculiar, as I've never seen some of them until now. This'll be a long post with 12 different fossils in need of a name so brace yourselves hahah: All fossils found in Toronto creeks - Ordovician Era - Georgian Bay Formation 1. I thought this was the typical Treptoceras crebriseptum that I always find at my local creek, but when I cracked it out from the matrix I noticed it was perfectly smooth. Maybe its the living ch
  11. Hi everyone!!! I had the afternoon to myself today because William and Viola are at day camps this week and my husband was busy, so I decided to check out Mimico Creek (Georgian Bay Formation, Upper Ordovician) by myself for a couple of hours. I didn't make many finds, but the finds I did make were super-amazing (by my standards, anyway ). As I was walking along the creek when I first arrived, I was checking out the wall of rock when I noticed a pattern: After gently prying out the rock, this is what I found: Hooray!!!!!!!!!! My first Flexicalyme
  12. Hello to all! Its been a very long time since I've been on here, but my recent trips around the creeks in Toronto, Canada (in the Etobicoke area) have yielded some of my largest and most defined finds of all time, here are some of the nicest Orthoconic Nautiloids I had found yet: Probably the nicest one in my collection at this moment, found almost completely by fluke when I hit a rock with my pick and this bad boy showed up Imprint made by the previous one These last couple would be way nicer, if only I could find a way to get it out of t
  13. Hello all! Here are some of my my favourite scenery and fossil pictures from the last few weeks! Decided to hit up some new spots way up in the north end of Toronto along the Humber river - which yielded some very nice shells and crinoid segment (instead of the usual nautiloids). I'm in the midst of getting the weird nautiloid section so stay tuned: Lets kick things off with a couple very pretty shells and crinoids from the north end trip: the 7 shells from the left are Ambonychia, with the two black right shells being Pholadomorpha pholadiformis (I believe). Some
  14. Hi all! I ventured out to Mimico Creek in Toronto, Ontario today to look for fossils. It was very cold and the rocks were frozen together, but I managed to pry out one large rock that has some interesting fossils on it. The fossils are from the Georgian Bay Formation (Upper Ordovician). The rock caught my eye because I could spot a few Cornulites flexuosus on one side, but after I brought it home and washed it, I was pleasantly surprised to find that the other side had even more interesting items on it! I'm not exactly sure of what I'm looking at, though, so I'm asking for your
  15. Hello! It was found in the Georgian Bay Formation - Ordovician period, in West Toronto. It was found after cracking some rocks on the riverbanks of Etobicoke creek. I recently came across a rather peculiar fossil, I initially though it might have been an ammonite, but those didn't exist until much later than the Ordovician period. It seems to be slightly ribbed, with a bit of a spine.
  16. Had fun kicking around. Found usual stuff. Cleaned dirt off it and enjoy looking at all the fossilized creatures.
  17. Hello again! Sorry for the constant posts, but I've been finding a lot of amazing stuff recently! Anyways, as the title says, this was probably one of my best hauls ever for a single day! I managed to find over a dozen different nautiloid chunks and was able to extract toooooons of super well defined and complete brachiopods from a matrix piece!! This will be another 3 part post as i have lots of pictures: Here was the full haul for the day, with ruler for reference (notches in cm). Here are some alternate angles of the nautiloids. I going to assume/believe t

    Treptoceras crebiseptum orthocones

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

    Treptoceras crebiseptum specimens. The one on the left comes from Mimico creek. The blue grey one on the right is covered with bryozoans and comes from the Humber river area and is complete is actually missing the living chamber. Both belong to the Georgian Bay Formation.

    Another classic trip

    Another decent haul over the last few days. Bunch of nautiloids and whatnot, a couple mussels. These were my favourites from the last 2 days in the river. This was a biiiiig nautiloid, and after cleaning it I realized there were two of them! wowowowo! (Sorry the picture didn't turn out quite that nice) This is probably one of my highest quality specimen so far, although it did break near the end when extracting it from the matrix.
  20. Wowowow I was very surprised to find all this amazing stuff today at my favourite river bank fossils spot of the Etobicoke creek. I managed to snag a whole lot of stuff today, some Orthoconic Nautiloids, Brachipods and what I believe to be the nicest tentaculite I've ever seen!!! The fossils are from the Georgian Bay Formation and they were found in the broken up "rock fields" next to the creek. This is going to be one of my longer posts, so I will have to split them up into section. The full haul, with the typical estwing 22 ounce rock pick (33 cm from bottom of the han
  21. I had a disappointing outing to Joshua Creek looking for lamp shells on the weekend. When I got home, I saw one of the rocks had a wonderfully detailed critter on the side...I was very pleased. I suppose it is some kind of encrusting bryozoan. Most that I find are branching types with smooth surfaces and little evidence of the apertures for living inhabitants.
  22. Hello there! I took advantage of the nice weather we've been having to visit Mimico Creek in Toronto, Ontario (Georgian Bay Formation, Upper Ordovician) yesterday afternoon. Here are some photos of specimens that I'd like help identifying - perhaps @Tidgy's Dad would like to have a look? Firstly - the whole rock which contains the bryozoans and the unknown black objects: Specimen #1: a nice branching bryozoan - perhaps Homotrypa? Specimen #2: a nice encrusting bryozoan (there are actually two of them) - perhaps Mesotrypa?
  23. Hello, I recently cracked open a rock to find one the most pristine and unusually shaped fossils I've seen in a looong time. I predict it might be the edge of a bivalve shell poking out, but I wanted to know what others might have to say about this. It was found in the rock deposits of the rivers in Toronto, Canada, and is part of the Georgian bay formation. Also, only the bottom half seems to be completely crystallized and is translucent, whereas the top is relatively opaque: I am somewhat worried about totally ruining the fossil if I try to further crack
