Can you help identify this bone/fossil found on Lake Huron beach?
Mulholland posted a topic in Fossil ID
The other week I found a bone(left) on a Lake Huron beach (Ontario, Canada). The bone is roughly 2.5cm tall and 3cm wide, 1cm thick. To the right of the bone is a "rock" I found yesterday. I felt it looked too similar to the bone I had found. Here they are back to back. Does anyone know what kind of bone this is? And does anyone know if the specimen to the right is infact a fossil, or is it just a rock? Hopefully this is structured well enough. If you have more questions please ask! This is my first post here so thanks for having me. - Chris

Hi there! I'm located in Collingwood, Ontario , Canada along the shores of Georgian Bay (grey shale and limestone, ordovician). I became fascinated by fossils in this area after finding a perfectly formed gastropod infill and half a trilobite impression washed up at the local beach. I don't know a lot about geology or fossil ID yet so I'm hoping to learn a lot from this forum! Cheers!

Hi, I posted my hello over in the member intro thread. I’m new here and have been collecting fossils on my farm for the last 17 years. I have little idea of what they once were but I’m very curious. Here’s part one of three. Thanks.

Hello there! I took advantage of the nice weather we've been having to visit Mimico Creek in Toronto, Ontario (Georgian Bay Formation, Upper Ordovician) yesterday afternoon. Here are some photos of specimens that I'd like help identifying - perhaps @Tidgy's Dad would like to have a look? Firstly - the whole rock which contains the bryozoans and the unknown black objects: Specimen #1: a nice branching bryozoan - perhaps Homotrypa? Specimen #2: a nice encrusting bryozoan (there are actually two of them) - perhaps Mesotrypa? More to come...

Everyone, Can someone identify this coral-type fossil? It's completely empty inside like a clam and has gills like a mushroom. I've looked through lots of photos in the Forum gallery to no avail. Nothing is even close. The 'top' isn't flat; it's a dome like the tip of your thumb, with holes on the tip. In the 'mudstone' matrix there's also a typical rugose coral. This was a loose rock in the area of the Kenogami Formation of limestone in Northern Ontario. Puzzled, Lauren16

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

Took this opportunity to head to the shores of Lake Ontario in Whitby and find some trilobites, among other stuff! Edit: Kane corrected this - they're nautiloids. Cheers!

Hi again! Over the weekend, I posted pictures of small fossils in a rock I found at Mimico Creek in Toronto, Ontario (Georgian Bay Formation, Upper Ordovician). I've created this new post just for the shiny black specimens that I found in the rock because a consensus wasn't reached regarding their identity. Each of the two specimens pictured below are 5mm long. My question is: are these items scolecodonts or conodonts? I was leaning towards scolecodonts but I wanted to see what others have to say... Thanks once again! Monica

Hello everyone, I've joined The Fossil Forum to learn to distinguish what's worth bringing home when I'm out exploring. I'm in Northeastern Ontario, Canada which is Canadian Shield (igneous), except farther north where there is limestone - but almost no road access. (Almost!). I've been enjoying going through the photos and descriptions on the Forum. Am not discouraged that the 'treasures' I posted turned out not to be fossils, because I learned from you what to look for next time. It was -23 Celsius this morning but Spring is surely coming!

Hi all! I ventured out to Mimico Creek in Toronto, Ontario today to look for fossils. It was very cold and the rocks were frozen together, but I managed to pry out one large rock that has some interesting fossils on it. The fossils are from the Georgian Bay Formation (Upper Ordovician). The rock caught my eye because I could spot a few Cornulites flexuosus on one side, but after I brought it home and washed it, I was pleasantly surprised to find that the other side had even more interesting items on it! I'm not exactly sure of what I'm looking at, though, so I'm asking for your help. I'll tag @FossilDAWG since he's quite knowledgeable about fossils in my area Firstly, here's the whole rock so you can get an idea of the size of the fossils within the rock (i.e. they're generally quite small): Now on to the fossils! Here are some shiny black items that I've never seen before, but they look like scolecodont Oenonites sp. - what do you think? (I only circled the items that look sharp enough to be identified - the other black items I'm very not sure about!) Here are a couple of long, thin, and delicate-looking crinoid stems - can they be identified at all? Perhaps something like Ectenocrinus simplex (which does occur in the Georgian Bay Formation)? (The second one is located between the branching bryozoans which I think may be the bryozoan Homotrypa sp.) More to come...

Is this a fossil or geologic?

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...

Trypaulites calpyso Trypaulites erinus Total: 40 New: 17 I'll be parking all my trilobite hunts for the year in this thread. With winter ending much sooner than we are accustomed to up here, it's about time to get back into the hammer-swing of things. This year is an ambitious one, no less on account of having spent some quality time with old literature, maps (new and old), to plot out a series of areas to prospect all across the province. A significant amount of fieldwork is planned as part of a broader research project. This past weekend was the season opener for me, with temperatures hitting about 4 Celsius on Saturday, and near 12 Celsius on the Sunday. By now, almost all the snow has burned off, with just a few shadier spots remaining. This is the view as I set out through the bush around sunrise. The ground was still frozen, which was fine as it made trekking over mud much easier.

Hi Everyone, My fossil addiction started about 50 years ago. Other things in life have taken my attention, but last night I realised I had spent an hour with my dollar store reading glasses looking over ONE rock to see what I could see. I figured I either needed an intervention or a forum, so I picked a forum. My former mother in law passed away back in 2004, she had a massive collection of fossils, and now they are all mine. A few months ago my ex urged me to go over them to see which can be donated to museums, which can be sold, and which can go on a probable large set of shelves to make me happy while I'm up in Ontario. Once I'm able to better identify what I'm seeing I'd like to start prepping those which haven't already been done. I have a lot to learn. I've joined a few pages on Facebook and I'm hoping between the words and the pictures I'll pick things up quickly.

I've had this on my desk for years. I am almost positive I would have found it on the north shore of lake Erie in southwestern Ontario. Can anyone tell me what I am looking at?

Hi again! This past summer I purchased a small rock with 4 edrioasteroids on it, and I was hoping to get your help in identifying them. The seller said that the rock is from the Upper Ordovician Verulam Formation in Gamebridge, Ontario, and he/she said that the following 3 species of edrioasteroid are on the rock: Cryptogoleus chapmani Isorophusella incondita Belochthus orthokolus Can anyone tell me the specific identity of each edrioasteroid? Thanks so much for your help! Monica Photo of the whole rock: The two edrioasteroids on the right side of the rock - one is quite big (we'll call it Specimen #1) and the other is quite small (we'll call is Specimen #2): The edrioasteroid in the middle of the rock (we'll call it Specimen #3): The edrioasteroid on the left side of the rock (we'll call is Specimen #4):

Evening all, we found this tooth about a year and a half ago in the shallow waters of Duck Lake in Parry Sound, Ontario, Canada, just a couple of inches below the sand. I have no clue what it is but I am guessing some sort of tooth - curious if anyone has any ideas. I have added one additional photo in the comments section as I couldn't make the pic any smaller to put in this original post. Thanks and let me know if more info is needed.
