This was an oddity in my Dundee Formation material (Mid-Devonian) I decided to bring home out of curiousity. The material itself mostly contains white silicified fossils in sandy/packstone pulses with some grey crystalline chert horizons. The colouration of this piece, and its general shape, gave me pause as it seemed a bit out of place. Initially I thought, "possibly a fish bit?" (stout spinal process)? but the internal structure didn't strike me as likely. The specimen measures about 7 cm long. My second thought was possible plant material, but I am rubbish on plant identification in the Dev

So I started fossil hunting and collecting recently. I dont have much knowledge on fossil identification and am not even sure if some of the "fossils" I've found are even fossils and not just cool looking rocks. Was just hoping people more knowledgeable on the subject could share what they think are fossils and if they know what types they are.

Lise found the first blastoid of the year at Arkona, during last weeks spectacular warm spell. She also found the first Petoskey stone, though there was very little of Lake Huron’s shoreline free of snow and ice. I, however, found a stromatoporoid. An interesting piece, from a chunk of armour stone, quarried from somewhere or other. A spectacular ice nugget was also found.

A friend of mine last weekend was digging near an old creek bed on his farm property in Southern Ontario and came across a "Weird rock" as he described to me that I should check out, when I got to his house and he presented the approx. 10lbs "weird rock" my jaw hit the floor, this weird rock was 100% a tooth from something that lived a looong time ago. It was the coolest thing I'd ever seen before, so after an hour of googling we realized by the cusped shapes on the tooth this was a mastodon tooth....in his back yard practically. We are planning on going back to dig this weekend, so my questio

I was able to get out three times to three different local spots. Fairly underwhelming results, but it was nice to get back out in the field now that the snows have melted. The first two spots I had effectively tapped out last year, but it always pays to check in. The third one, featured here, was a new prospect. I had made a cursory visit last autumn, and then tried to jump the gun by going here at the end of February but the snows were still too deep. Exploring the Dundee Formation is admittedly a pretty niche focus. There is probably a good reason why it isn't the top destinati

Hello everyone, thanks for letting me join the site! I'm an amateur fossil hunter from Toronto who has made a few expeditions in the past months. I've found a few fossils of interest that I'd like some help identifying. Below are links to photos of the fossils in question on my iNaturalist page, along with some additional details. Thanks all in advance! The following were all found along the Don River in Toronto. 1. https://www.inaturalist.org/observations/68570190 2. https://www.inaturalist.org/observations/68573964 3. https://www.inaturalist.org/observations/685701

This is a work in progress, a kind of "master list" of trilobite species found in Ontario according to the available literature. In some cases, stratigraphy and taxonomic names have been modernized. Correlations are added where it is expected that species found in equivalent strata could be found in Ontario rocks. I have not included trilobites from the Hudson/James Bay area as there are a number of species there that still are in need of formal description. There are also a number of uncertainties that require more literature support before they are included here. I'll update this as more res

Hi, I found 2 large fossils on th e shores of Lake Erie Ontario and I do not have a clue what they are. Both of these fossils are approximately 24" in diameter. Can someone identify them?

Well, since moving to Ottawa, I haven't had the chance to go out fossil hunting. There wasn't a whole lot of info on the web about the geology here. So my wife and I decided to buckle up and find a spot ourselves (without any hammers or chisels). We tend to be very lucky people, but I was surprised by the THOUSANDS of trilobites we came across in a matter of 20 minutes. We were on the shoreline of the Ottawa river, we found a certain type of shale that was just crawling with them. If any lucky soul goes to the spot where we left all the remnants of our hunt, they will sure be having a good day

Can you please help me ID the fossil rock in the picture? Also would like to know anything about it you can share. I found it on the shore of Lake Ontario this afternoon. Thanks in advance!

New hunting location at Etobicoke Creek (Georgian Bay Formation)!
Monica posted a topic in Fossil Hunting Trips
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- 41 replies

Found another cool piece at work today- is it anything special? It came out of a load of rubble from the Milton Quarry, in Milton, Ontario.

Hi all! After reading about @Kane's autumn trip to Ontario's Formosa Reef (Amherstburg Formation, Lower Devonian), I was inspired to find it and check it out myself. With the help of Ludvigsen's 1986 paper entitled "Reef trilobites from the Formosa Limestone (Lower Devonian) of southern Ontario," along with Google Maps' Satellite View, I was able to locate the reef, so Viola and I made the 2-hour drive yesterday to search the site for some new fossils. Here's Viola standing atop the reef: This was my first find of the day - a rock with a brachiopod AN

Hi all! Yesterday I visited Formosa Reef here in Ontario (Amherstburg Formation, Lower Devonian), and I found these weird circular imprints on a few rocks - does anyone know what they are? @Kane Thanks a bunch! Monica photo with ruler for scale: close up photos:

Today Deb and I made the two hour drive up to just outside the town of Formosa, Ontario, to have a look at the Formosa reef limestone, which is part of the Amherstburg Formation. This road cut is the type locality for this material, and it was humbling to be at the exact same location that researchers of yesteryear such as Ludvigsen and Fagerstrom derived their material that formed the basis of their published work on it. Here are some shots of the road cut. Hardly does it justice. This represents a single, massive biohermal knoll. I've wanted to visit this site for a while now, h

Acanthopyge contusa hypostome to the ROM
Monica posted a topic in Partners in Paleontology - Member Contributions to Science
Hello everyone! I wanted to share some good news with you all... On Monday, March 16, 2020, I visited "Formosa Reef" in Ontario (Amherstburg Formation, Lower Devonian) for a little fossil hunt. One of the rocks that I found at the site had a trilobite piece that @piranha identified as the hypostome belonging to the trilobite Acanthopyge contusa. When I asked him if he knew of any museum/researcher who might be interested in my specimen, he suggested that I contact the Royal Ontario Museum (ROM), and so I did. First, I emailed David Rudkin, and this is what- 49 replies
