  2. 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.
  3. 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.

    fossil id

    Hello looking to identify thi8s coral found in Ottawa, Ontario
  5. 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.

    A few Fossils from recently

    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

    A fossil rock from Lake Ontario

    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!
  12. I found it in a gravel near the road. Please help me identify it.
  13. 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...
  14. 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...
  15. 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:
  16. 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
  17. 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.

    Quarry Find

    Hello! Found these cool pieces while at work- they came from the Milton Quarry in Milton, Ontario, Canada. I am completely new to fossil identification, but am very interested to learn more! Can anyone tell me what these might be?
  19. I am posting some pics of my trip to Etobicoke, Ontario on the Georgian Bay formation, Lower Member. I only went a couple times to different localities in Etobicoke since the lockdown put a strain on my wanted public transportation service. I visited the Humber River and Mimico Creek. I only came home with 2 specimens from the Humber while I didnt take anything home from Mimico. This year's winter has been mild so that is why I believe there has not been any turn around for [good/unusual/extraordinary] material. I recall back in 2015, which had a rough and severe winter, generated more good fossils for me than this year's mild winter. I didnt have to do a lot of digging and just surface collecting just to find good specimens when the winter is rough before the following Spring and Summer. The ice didnt form thick and did not cause any strong erosion in the creeks in my opinion. These pics are from the Humber River This right below is a partial Treptoceras crebiseptum I collected along the bank. Sorry for the blurry pic, this one is a Pholadomorpha pholadoformis.

    Trilobite?

    Hi I just found this while fossil hunting Saturday and am wondering if it could be a piece of a Trilobite? And if it’s to hard to tell is there anyway I can prep it without breaking it to reveal what it is? Thank you!
  21. Note: This is a follow-up post to my original post of about a week ago. I found this trilobite fossil near Eganville, Ontario, Canada. When I first picked it up, I thought it was broken but then I noticed that it was just slightly rolled and the pygidium was curved downwards. I have already posted a couple of pics of this Isotelus as found, but now that I have had it prepped (thank you Malcolm), it looks even better so I thought I would share.

    Partial Trilobite Fossil Found

    Hi - this is my first post to this group. I found this partial trilobite fossil this past summer in Ordovician limestone near Eganville, Ontario, Canada and I am hoping that someone here can help me identify the trilobite species it belongs to. This piece measures 3.5 inches in length by a little over 2.5 inches wide and I believe it is the pygidium and most of the thorax (so a little more than half of the full trilobite). Also, it has a little over 1/2 inch in depth, so it is not completely crushed flat. I would have much rather found a full trilobite - and I do have a full trilobite that I found that I am having prepped, that I will post at a later date - but I am very happy with the size and condition of this sample. I broke it out of the rock in this condition - no prepping has been done to this sample. Any thoughts?
  23. Hi everyone, I found this fossil in Eastern Ontario. I was wondering if anyone can identify the fossil. I don't think it's a trilobite. I'm also wondering if it can be extracted. I believe it's in limestone. Thanks!
  24. My daughter found this small piece washed up on the beach. It is apprx 1/4 inch thick and has a grover through top. It was found on Beach 6 of Wasaga Beach Ontario.
