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.© (©)

Favosites sp. from the Devonian Hungry Hollow member in Arkona, Canada. One of the more interesting corals I've collected, I'm trying to narrow down the species if possible. Any ideas?
-
I found this orthocone a while back at Arkona (devonian) and I thought it was dolorthoceras, but now I am not so sure. It has a strange mark protruding from centre of each chamber. Any help would be appreciated! d!

Hello there! This past Saturday, I went on a "field trip" to Hungry Hollow near Arkona, Ontario (mid-Devonian in age), and I found one weird item. It's an echinoderm of some sort, but which sort? A crinoid holdfast? Something else? Please see the photos below and let me know what you think. (By the way - I didn't make it home from work in time to take photos in natural light today, so I apologize for the fairly poor photo quality - if it's sunny tomorrow I can get better pictures then. And I also apologize for my blue finger in the photos - my students and I were looking at cheek cells under the compound light microscope today and some methylene blue got on my fingers - oops!) One end showing the pentaradial symmetry: The other end not showing much: Side photos: Thanks for your help! Monica

My 5 year old found this near a river edge in Southern Ontario. Any ideas?

Hi all, It's been a while since I posted a trip report but I was feeling like posting last evening as well as testing out my new photography rig. I moved houses two years ago and lost my lovely brick wall backdrop (the exterior of back of the house) which allowed photography in natural light. The new house is all vinyl siding outside and I have more shade so less opportunity for good sunlit pictures. However, one corner inside the house has a bricked area where a wood burning stove used to be so I have decided to set up some lights there. The pics came out ok so let's proceed with the report. I recently went up to the St. Mary's quarry in Bowmanville, Ontario on a scheduled trip with the local Scarborough club and also stopped off at Arkona while in Canada. I did pretty well at Arkona where I found four Eldredgeops trilobites and two Blastoids among other finds. Nucelocrinus elegans from the Hungry Hollow member of the Widder formation. Sorry, no pics of the Trilobites due to some back spasms but I got these pics of a nice Atactotoechus fruiticosus branch also from the Hungry Hollow Member of the Widder formation. Then I went to the St. Mary's quarry on Sunday where I took a tumble down the rock pile and hurt my ribs. Lucky for me my hard hat took the brunt of the impact my head made with the rocks. With nothing broken and still able to move around, I stayed closer to the ground and found this partial, eroded Isoltelus sp. that is inverted and still shows the Hypostome in place. I also found a plate with Graptolites but that was too heavy to hold and photograph last night. I'll post it tomorrow maybe. Finally, I drove home on Monday and stopped off at a place in New York where some of the Kashong Shale member of the Moscow formation is exposed and found these two surprises. A cephalon of a Dipleura dekayi with some of the shell material eroded away. I think the eye is intact and waiting to see again once some rock is removed. And here is a closeup of the shell on top where you can see the stippled pattern where sensory pits used to be. Lastly I found a pygidium that I am not sure of the genera on. Possibly a Basidechenella sp.? So not a bad trip at all, despite the injury. Good news is that I am healing nicely but still have some soreness and muscle spasms. I'm looking forward to my next trip up in the spring and hopefully will avoid the health scares.

Found this one in Bowmanville (Mid Ordovician, Cobourg? Formation) last weekend. My best guess is Thaleops laurentiana cephalon but id like to have a better idea what it is before I attempt any more prep. Have not tried yet but probing with air abrasion looks like it will be difficult since the matrix is full of calcite or some other crystals. @Malcolmt @Kane @Northern Sharks

Hi yesterday I went to the Ancaster gem and fossil show I got a couple things just wondering what do you think of them? First to last theropod bone fragment from cedar mountain formation Utah the they said it was found with identifyable bones that are theropod next dinosaur coperlite from Madagascar mahajanga formation last triceratops tooth hell creak Montana.

Unknown item (sponge?) from the Credit River in Mississauga, Ontario
Monica posted a topic in Fossil ID
Hello there! Last month, I visited the Credit River in Mississauga, Ontario, Canada (Georgian Bay Formation, Upper Ordovician) to look for some fossilized corals. In addition to a bunch of weathered colonial rugose corals, I found an item that I think is something, but I'm not sure what - perhaps a sponge? Here are some photos of it: Side view - dry: Top view - dry: Top view - wet: Thanks so much! Monica

Here is an interesting potential fossil that I found in Oakville, Ontario. From fossils found in nearby rocks, I think this is from the Georgian bay formation which is ordovician in age. I don't know if this is a fossil, it could just be an interesting deposit of oxidized pyrite, but I would appreciate any help identifying this.

We took our girls fossil hunting near our house for the first time. We found rocks with lots of little brachiopods but I also found this. Is this a cross-section of a cephalopod maybe?
-
I found this last week Pretty cool kinda looks like a squished dinosaur haha what is it
-
I recently found this trilobite tail with a piece missing out of it on both positive and negative sides. Could it be a bite mark?

I was able to fit in some prospecting for new sites while the missus had a week off from work. Obviously I couldn’t monopolize all the vacation as the main purpose was to visit a relative and lounge on a beach. Regularly accessible and productive Ordovician sites in Ontario are few and far between, mostly relegated these days to the biannual trip to the quarry in Bowmanville, or to the creeks around the greater Toronto area (GTA). Trilobite collecting in Ontario is massively curtailed by a confluence of factors sadly common in so many other areas: development, quarries that no longer permit access (even to clubs), laws governing protected areas, and over-collecting. We have a rich abundance of trilobites in Ontario, just as in New York, but accessible sites remain a problem. This means defaulting to the traditional method of prospecting new potential areas, and even putting a hard shoulder into shovelling a lot of soil to expose bedrock. This means smaller areas that are more easily exhausted. A pic of our haul from the two spots:

Another trip to Etobicoke Creek, this time near Sherway Drive. There were lots of nice things, but quite the same as usual, so I concentrated on looking through the gravel for smaller pieces and ended up with a box of knick-knacks to explore. As usual, my wife found all the interesting items. At one point I picked up a rock and got surprised by a little snake. He was really steamed. We had a delightfully relaxing outing.

This was found in Cayuga Ontario (Devonian) in 1988 and is still marked in my collection as an unknown. I have had a number of suggestions over the years as to what it is but nothing that screams that's it for sure. I always thought that it was echinoderm of some type but others have suggested eurypterid. Any thoughts. It was found at surface level of an abandoned water filled quarry so there is no assurance that it actually originated at that quarry but it probably did as it looked like the same matrix as the surrounding rock. Please jump in with your thoughts... I would really like to figure out what it is as I have nothing else that remotely looks like this

I found this concretion in what I believe to be Lockport dolostone, which is silurian in age. At first I didn't think much of it but then I noticed the surface has a faint texture of cracked shell. I was wondering if this could be a silurian ostracoderm like Tremataspis?

I was determined to trace a shale layer into a hillside, and managed it: what a joy to discover more shell imprints. The genus I'm looking for is Rafinesquina, or something similar. Also got some colonies of things and trace fossils out of the muddy creek area. This place is the tip of the Georgian Bay formation that pokes into Oakville. It yields its treasures sparingly and you really have to work for it! The rocks were so heavy...I had a bag of goodies plus 3 heavy slabs...barely made it back to the car. I left 4 spectacular slabs that were too heavy to manage...might go back for them when I feel ambitious.

Hello there! I was inspired by @markjw to check out the Credit River here in Mississauga, Ontario (Georgian Bay Formation, Upper Ordovician) because where I normally hunt there are typically no corals and I'd love to add a couple to my collection. Consequently, I went out for about an hour this morning before the family got up in order to try my luck, and I'm happy to say that I was successful!!! Based on information provided by @FossilDAWG in other threads here on TFF, I think all of my colonial rugose corals are Favistina calcina - here are photos of three of my specimens: Specimen #1 - side view: Specimen #2 - top and bottom views: Specimen #3 - top and bottom views: more to come...
