    Reduction spots and microbial life

    Was examining several of my rocks (sandstone & mudstone) that have light-coloured spots, such as the images of 3 rocks below. I read "Reduction Spots in the Mesoproterozoic Age: implications for life in the early terrestrial record" (Spinks, Parnell, Bowden) -- well, the little that I could understand -- and was wondering whether any of these 3 rocks might be an example of this. The spots in my rocks do not seem to have the "dark concretionary cores" that the article says are often present in the spots, but I was curious to know more. I'm having doubts but thought I'd ask. Thanks for any ideas. Rock #1: Rock #2: Rock #3:

    Would this be a bifoliate bryozoan?

    Found a couple of days ago along Lake Ontario, in Toronto: This is a follow-up to my previous post some weeks ago: I stand corrected about the "graptilites" part! Turns out the fossils on that rock were bifoliate bryozoan. So I'm wondering if the present specimen submitted here is also a bifoliate bryozoan. Thank you!
  14. I know crinoid "forests" are a dime a dozen, but still its nice to find one so packed . . . And some bryozoan pieces, my first that I can identify with a bit of confidence . . . but please correct if I'm mistaken. Cheers!

    More Ordovician finds at Mimico Creek

    Here are a few more of my recent finds at Mimico Creek. As always, I'm grateful for comments and IDs to increase my knowledge! By the way, I'm interested in connecting with others in the Toronto area to go on fossil hunts. Cheers! Camille

    Toronto (Upper Ordovician) Fossil ID

    Hey everyone! I found my first fossil last weekend in a creek near the Don River in midtown Toronto. From my knowledge reading through this forum, it seems to be packed with crinoid stem fossils. I’d really appreciate a confirmation, to learn more about the age of the fossil and maybe even the species.
  17. 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 more good fossils for me than this year's mild winter. I didnt have to do a lot of digging and just surface collecting just to find good specimens when the winter is rough before the following Spring and Summer. The ice didnt form thick and did not cause any strong erosion in the creeks in my opinion. These pics are from the Humber River This right below is a partial Treptoceras crebiseptum I collected along the bank. Sorry for the blurry pic, this one is a Pholadomorpha pholadoformis.

    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?
  19. 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 have also found mounding round stomatoporoids ranging around 4 inches to over 1 ft in diametre. I think this must be Stromatocerium. With the stromatoporoid with the prominent mamelons I have found it encrusting Prismostylus sp. specimens on the locality (what an odd association). This stromatoporoid, from my experience with the locality, usually just grows over the size of an open hand. Is this Labechia, the one with prominent mamelons?
  20. 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 shale. At first I didn't think anything of it and figured I'd never find anything THAT nice in shale. But, jump to a week later: While exploring a new location, I happen across a large section of layered shale on the riverbank and figured I'd try my luck - and started doing some digging. I pretty quickly came across a shell. A second shell. Then a third, fourth, fifth, and after chipping back the layer I found dozens of very tightly knit shells to my surprise. I was shocked to find anything after thinking for years that Toronto shale held almost nothing of interest. But still - they were ambonychia shells which I already have plenty of in my collection. So I keep looking around and chipping away at other layers, thinking maybe I'll find something a little more exciting. An hour goes by while digging in a somewhat awkward position, and my legs start to fall asleep so I readjusted my legs and out of the corner of my eye I noticed something right near my knee. My heart absolutely skipped a beat as I realized what I had found: A perfect and complete trilobite in the shale. After taking a closer look I realized there was in fact TWO of them right near each other! I hadn't found a trilobyte of this quality since grade school when I used to go with my father - let alone two. I just sat there for about 2 minutes staring at them, thinking they were going to shatter as soon as my pick got anywhere near them. Ultimately, luck played in my favour and the trilobites came out perfectly! But, the story doesn't end there, oh no! So now I'm going back to all these old places, primed with the fresh new knowledge of how to hunt shale. Although the work is pretty messy and uncomfortable, it seems to pay off quite nicely. And before I know it, a couple days later I end up finding yet another trilobite. But the crown jewel of the month came last weekend when I found two different nautiloids - one being an absolute MONSTER specimen, and the other being my most complete nautiloid ever (it even included the tip at the very end!). I just gotta give a big thanks to the people on this forum. Without the knowledge shared on this forum, I would likely have still been stuck in my ways avoiding any piece of shale in sight. I also have also included some other fossils that I found this month. [All fossils found in Humber, Etobicoke and Mimico river/creeks riverbanks - located in Toronto ON, Canada // Georgian Bay Formation // Ordovician (485.4 - 443.8Ma)] The first set of trilobites In Situ from humber river. The first two trilobites on the left and the later one on the right. The many pieces of nautiloid that came out during extraction. They unfortunately broke VERY easily so I figured there was no point stressing about it coming out in less than a dozen pieces. Here is what it looked like when all the pieces were assembled together (with the help of a little super glue of course). It even seems to have the very tip of the nautiloid as well (which would be a first for me)! here are a couple other decent pieces I found as well:
  21. 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...
  22. 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:
  23. 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:
  24. 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: cephalon (with a nice Ambonychia radiata bivalve next to it) and a chunk of thorax (circled in red) Flexicalymene granulosa: 2 cephala (one is quite large and the other (if it is a F. granulosa cephalon - I'm not sure if it is) is small and is circled in red), 2 pygidia (circled in red), and 1 slice through a thorax (circled in red): More to come...
