Some recent Upper Ordovician finds at Mimico Creek, Toronto
Rogue Embryo posted a topic in Fossil Hunting Trips
First, if anyone in the Toronto area is interested in going fossil hunting along Mimico or Etobicoke Creeks, I'd welcome the company! Before I get to a couple of better finds, I'm curious to know what the black fragments are below, which I often find embedded in the shale. Can someone please give me a clue about these? Some orthoconic cephalopods: The next two are the same fossil from different perspectives: Some bivalves: Bryozoans:- 4 replies

Found this lovely pair of bivalves in Mimico Creek over the weekend and hoping to get some help on ID. It looks like either Colpomya or Cymatonota, based on images I've seen. Any ideas in this? Camille

Is this a kind of favosite? (Georgian Bay Formation, Ontario)

Maybe I'm imagining patterns. Coral? Geological process? Found along Lake Ontario, among other whitish rocks from elsewhere, most very fossiliferous, arranged along the shore.

Field collection by Camille Martin, April 4, 2022 Note the nummuloid siphuncle in the bottom image -- two "buttons" are visible (circled). A good candidate would be Treptoceras crebriseptum.© Camille Martin

Wondering whether this is a bryozoan colony or a coral. In the detail, I noticed a honeycomb pattern, but I think both bryozoans and corals can have such a pattern. Thanks. Camille

I found these two fossils from Mimico Creek in Toronto, Canada and they both belong to the Georgian Bay formation, late Ordovician. The first one I believe is a Pseudolingula, but I can't really nail it down to a species level. The other is a bryozoan, and I was thinking of Prasopora. What do you guys think? The brachiopod I found in shale, but the bryozoan in a limestone bed with other bryozoas. The brachiopod: The bryozoa:

Trip to Etobicoke Creek (Georgian Bay Formation, Upper Ordovician)
Rogue Embryo posted a topic in Fossil Hunting Trips
My first visit to Etobicoke Creek in several years yielded a few finds, but will search other spots along the creek in the coming weeks. Some cephalopod fragments: A "misshapen" cephalopod? An outline on a perfectly flat rock: Not sure what these are; not much detail: Two of the better Pholadomorpha pholadiformis specimens: Camille- 2 replies

Details are indistinct, but based on shape and location (Georgian Bay Formation), possibly Ambonychia radiata. Field collection by Camille Martin, September 25, 2021© Camille Martin

Upper Ordovician ichnofossil - bifungites (?)
Rogue Embryo posted a gallery image in Members Gallery
From the album: Camille's fossils - Georgian Bay Formation
This dumbbell-shaped ichnofossil measures about 7.5 cm long, including the terminations -- considerably longer than the Ordovician and Devonian bifungites specimens described in Pickerill and Forbes, "Bifungites of Halli from the Ordovician (Caradocian) Trenton Limestone of the Quebec City Area" (1977).
