A nice Dictyonema flabelliforme dendroid graptolite from Oslo Fields in Norway. It's Tremadoc, Lower Ordovician in age and is thus maybe around 480 mya. Another angle :

The dimensions given are for the largest specimen. The block is 11.5 com at it's widest point by 10 cm and 2 cm deep. Most of the of the other species ascribed to this genus in Morocco are now considered junior synonyms. See https://link.springer.com/chapter/10.1007%2F978-3-319-04364-7_199 Notice that they are all aligned in one direction as they were buried by a mudflow sweeping in from the continent. The arms, bodies and stems are all pretty much aligned. This seems to have occurred fairly regularly in this area at this time. Also notice younger, smaller specimens have fewer plates and arms.

Hello, this slab is from the Kope Formation, particularly Upper Alexandria sub-member within Delhi Township, Ohio. I am unsure if these rounded "structures" are bryozoans, echinoderms, or brachiopods, but i'm leaning more toward bryozoans. Fauna on the slab include: -Cincinnaticrinus, Ectenocrinus -Retrosirostra OR Dalmanella (hard to distinguish) -Bythopora -Isotelus, Flexicalymene -Ambonychia If anyone has an idea as to what the round objects are, please comment! Thank you! EDIT: I now believe these are individual cephalopod chambers that were filled with hash. I credit a fellow UC student!!! Now I wonder if anyone else thinks similarly.

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: Cheers, Camille- 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

Not sure on the ID for this bug. As stated earlier, these guys are formally undescribed - though I’m sure there’s a genus out there that matches this blind trilobite. -

Two sets of orthoconic cephalopods (Upper Ordovician)

From the album: Camille's fossils - Georgian Bay Formation
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
