So I was at Arkona with my family recently, and at the flooded pit my mom found this piece It's about an inch long It's the hole(?) that I'm confused about. The only thing I can think of is some type of coral, but I really have no idea.

My daughter found this rock at Kew Beach in Toronto, Ontario, Canada. She thought her dad knew everything but he can't help with this! She is very excited to know what she found and Google has made us more uncertain rather than certain. We're hoping the community here can tell us what she found or at least point us in the right direction. Thanks, Steve & Big Bunny

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.

Found this fossil loose on a limestone shoreline on St. Joseph Island located at the north end of Lake Huron in Ontario, Canada. I am a civil engineer and have some experience with rocks but I’m fairly new to fossils. Any help identifying would be great!

From the album: Trilobites
Partial pygidium, ventral. Rare. -
I have been collecting fossils for many years, but this fossil is without a doubt the strangest and most mysterious of the fossils I’ve ever found- I would really appreciate your help in helping solve this mystery of what it is and how old it is! It was found on the rocky shores of Lake Huron in Southampton, Ontario. I initially was interested in it because it looked like a boot and I thought it was a native carving, but realized it must be a fossil of something I’ve never seen before. It’s very interesting to me because it almost seems to be coiled like a spine of an animal, but could also be strange coral- I have no idea. Very curious to hear what you think. Thank you for your help, Christian

Good Morning, I am hoping someone could maybe give me a little information on what I may have found. This was found on the shores of Lake Huron in Ontario. I found it as I was walking along the shores. It looks to be a fish head or an eel head maybe. There is a whole in top, and around the neck looks to be roughly cut or torn and a lighter grey material inside what appears to be the head cavity. Any help would be greatly appreciated. Cheers Chad Schofield

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 Devonian. It could, of course, just be a geologic feature, too, but the very conspicuous shape makes me lean toward fossil.

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.

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 destination for fossil collectors on account of lack of available outcrops, some very poor facies, and occasionally being brutally hard rock -- so much so that it is commonly used as armour stone for landscaping. Friday's prospect had quite literally hundreds of tons of locally quarried rock. Sadly, about 99% of it was not very gainful for trilobites, and was from a lower facies that is characterized by being a high energy packstone filled with crinoidal bits, broken brachiopods, and shreds of fenestrate byrozoans.

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/68570193 4. https://www.inaturalist.org/observations/68300323 5. https://www.inaturalist.org/observations/68573819 This was also found in Toronto, in a clean fill pile. A nice assortment of small invertebrates here. 6. https://www.inaturalist.org/observations/19866874 This one is a real mystery. Also from Toronto, among clean fill. A bone fragment? A piece of vegetation? Coral? 7. https://www.inaturalist.org/observations/68299911 These three were found today in Prince Edward County... 8. https://www.inaturalist.org/observations/69519088 9. https://www.inaturalist.org/observations/69532565 10. https://www.inaturalist.org/observations/69519075#activity_identification_0484c99a-6655-4e0f-8a1c-2ab2cd4c0fea And finally, this Trilobite fragment was found in the vicinity of Arkona. 11. https://www.inaturalist.org/observations/68299694

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: 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...- 41 replies

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 AND a gastropod in it - woohoo!!! This was one of Viola's first finds of the day and probably her favourite - a large and beautiful chunk of tabulate coral: Here is a photo of Viola and I just before we left the site after about 3 hours of fossil-hunting: Photos of the fossils to come...

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 he said: "Thank you very much for getting in touch and offering to donate your splendid little Acanthopyge hypostome! I've been retired from the ROM for 3 years now and am not permitted to act on behalf of the Invertebrate Palaeontology section, but I am copying these messages to the Curator and Collection Manager with my recommendation to accept your generous offer." "Acanthopyge contusa is indeed a relatively rare component of the Formosa trilobite fauna and the ROM collections do not hold any specimens of the elusive hypostome. Like your contact on The Fossil Forum I've not seen one from Ontario before, so your discovery is quite exciting ... at least for a self-professed trilobite geek such as myself! I'm hoping that my ROM colleagues, Dr Caron and Ms Akrami, will follow my recommendation to accept your offer, but I must leave the final decision in their hands." Just last night, I received two consecutive emails from Maryam Akrami (the current Invertebrate Paleontology Collections Manager at the ROM): "Thank you for sending the images and the information for the trilobite specimen. I am glad to let you know that we will accept your offer of donation. Just want to let you know that the ROM is closed until at least 5th April. If you would like to ship the specimen to us now, I can give you my home address. Once we have the specimen, I will send you a letter acknowledging your generous donation to the ROM." "Following up on my previous email (below), given the current situation and the advise against leaving our homes for non-essential reasons, perhaps it would be a good idea to wait till things return to normal and then ship the specimen to us. I hope that would be ok with yourself." So, once the ROM is up and running again, I'll be handing over my little Acanthopyge contusa hypostome to the ROM! I'll update this thread as soon as the donation has been completed. Here are pictures of the specimen in question: Thanks for reading, everyone! Monica- 49 replies

I had mentioned in prior posts that I had found a large trilobite (Isotelus apparently) and I just got it back from Malcolm so I wanted to post pics. I definitely wish there was less damage but the size is very impressive to me (about 8 1/2 inches long by 6 inches wide by about 1 inch high), so I really like this guy, especially since it is the first trilobite I found (earlier this year). The first pic is how it looked when I found it - it was covered in calcite and was barely recognizable (to me, anyway) as a trilobite. While part of me wishes it WASN'T covered in calcite, the fact that it was a large white-ish rock is what allowed me to find it, and I think the calcite actually protected it somewhat from the elements. The one side of the trilobite was completely encased in limestone, and Malcolm had to 'liberate it' - I can only attach three pics with this post but I will reply to my post and try to post more pics showing the prepping process. The second pic is the finished trilobite, with the ruler to show scale. The last pic has the 'little' 4 1/2" trilobite that I posted earlier in the foreground, to show the scale / size of the larger one. I am still working on my photographic skills, so sorry for the pic quality. This was found in Ordovician limestone in the Eganville, Ontario, Canada area.
