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

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

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.

Hi guys I recently found this nice sized Pholadomorpha pholadoformis at the Humber River in Etobicoke, Ontario. It belongs to the Georgian Bay formation and is late Ordovician in age. The specimen has pyrite in addition to the black film. Does this fossil have some sort of pyrite disease to it?

So I have been looking at my collection and it baffles me whether these two specimens are the same species with just different growth forms due to their deposition environments or are they entirely different species from each other? These stromatoporoids both come from the same locality (Streetsville, Mississauga, Ontario) in the Upper Member of the Georgian Bay formation, late Ordovician. Can anyone provide me with any PDF on late Ordovician stromatoporoids so I can nail down the differences between Stromatocerium and Labechhia? On the site where I collected these, I have also found mounding round stomatoporoids ranging around 4 inches to over 1 ft in diametre. I think this must be Stromatocerium. With the stromatoporoid with the prominent mamelons I have found it encrusting Prismostylus sp. specimens on the locality (what an odd association). This stromatoporoid, from my experience with the locality, usually just grows over the size of an open hand. Is this Labechia, the one with prominent mamelons?

Hello to all! Hope everyone is doing well, cause after my recent finds I am definitely doing well . So a little backstory: 10 years ago in grade school when I used to collect fossils with my father, we would never find any good fossils in shale. Always layer upon layer of the bland gray rocks with nothing even close to a fossil. For the longest time I never even bothered glancing at the large sections of shale dotting the many rivers of Toronto. jump ahead to the beginning of the month when I read some posts from @JUAN EMMANUEL showing some very nice nautiloids from shale. At first I didn't think anything of it and figured I'd never find anything THAT nice in shale. But, jump to a week later: While exploring a new location, I happen across a large section of layered shale on the riverbank and figured I'd try my luck - and started doing some digging. I pretty quickly came across a shell. A second shell. Then a third, fourth, fifth, and after chipping back the layer I found dozens of very tightly knit shells to my surprise. I was shocked to find anything after thinking for years that Toronto shale held almost nothing of interest. But still - they were ambonychia shells which I already have plenty of in my collection. So I keep looking around and chipping away at other layers, thinking maybe I'll find something a little more exciting. An hour goes by while digging in a somewhat awkward position, and my legs start to fall asleep so I readjusted my legs and out of the corner of my eye I noticed something right near my knee. My heart absolutely skipped a beat as I realized what I had found: A perfect and complete trilobite in the shale. After taking a closer look I realized there was in fact TWO of them right near each other! I hadn't found a trilobyte of this quality since grade school when I used to go with my father - let alone two. I just sat there for about 2 minutes staring at them, thinking they were going to shatter as soon as my pick got anywhere near them. Ultimately, luck played in my favour and the trilobites came out perfectly! But, the story doesn't end there, oh no! So now I'm going back to all these old places, primed with the fresh new knowledge of how to hunt shale. Although the work is pretty messy and uncomfortable, it seems to pay off quite nicely. And before I know it, a couple days later I end up finding yet another trilobite. But the crown jewel of the month came last weekend when I found two different nautiloids - one being an absolute MONSTER specimen, and the other being my most complete nautiloid ever (it even included the tip at the very end!). I just gotta give a big thanks to the people on this forum. Without the knowledge shared on this forum, I would likely have still been stuck in my ways avoiding any piece of shale in sight. I also have also included some other fossils that I found this month. [All fossils found in Humber, Etobicoke and Mimico river/creeks riverbanks - located in Toronto ON, Canada // Georgian Bay Formation // Ordovician (485.4 - 443.8Ma)] The first set of trilobites In Situ from humber river. The first two trilobites on the left and the later one on the right. The many pieces of nautiloid that came out during extraction. They unfortunately broke VERY easily so I figured there was no point stressing about it coming out in less than a dozen pieces. Here is what it looked like when all the pieces were assembled together (with the help of a little super glue of course). It even seems to have the very tip of the nautiloid as well (which would be a first for me)! here are a couple other decent pieces I found as well:

Hello! I recently decide to split a fossil that seemed to have the edge of a shell poking out. To my surprise, it split open to reveal something I have never seen before in all my years hunting in Toronto. I thought perhaps it might have been the head of an unusual trilobite, but I am not convinced for sure. It was found on the riverside deposits of Etobicoke creek in Toronto, Canada, which is part of the Georgian Bay formation. Let me know what you guys think @Malcolmt @Monica @JUAN EMMANUEL:

Some rare finds (from Georgian bay formation - Toronto)
Emthegem posted a topic in Fossil Hunting Trips
Oye I managed to get my hands on some very rare stuff (at least in terms of my local area) while hunting this last month in the Georgian Bay Formation in Toronto, Canada. Some of these fossils have been some of the nicest I've ever found, and will probably look even better with a little cleaning. Let's start things off with the usual nautiloids with a side of bivalves: Treptoceras crebriseptum I love these plates so much - they are currently some of my favourite fossils in my whole collection at the moment Treptoceras crebriseptum for the first three, the one on the far right might be a different species as it has a unique spiralling pattern.... Some MASSIVE nautiloid chambers, the biggest I've ever seen!!! A bunch of Rafinesquina brachiopods (I think). These are usually somewhat rare but I've found a lot recently so that is pretty cool A couple Ambonychia and what I believe are Pholadomorpha pholadiformis. A close up one the Pholadomorpha pholadiformis in the middle - one of the most exceptionally well preserved specimen I have ever seen!!!!

Identification for a large variety of different fossils (Georgian Bay Formation)
Emthegem posted a topic in Fossil ID
Hello all! So I've been looking through my collection and noticed a bunch of fossils that I haven't yet identified yet. Some of them are quite peculiar, as I've never seen some of them until now. This'll be a long post with 12 different fossils in need of a name so brace yourselves hahah: All fossils found in Toronto creeks - Ordovician Era - Georgian Bay Formation 1. I thought this was the typical Treptoceras crebriseptum that I always find at my local creek, but when I cracked it out from the matrix I noticed it was perfectly smooth. Maybe its the living chamber of the nautiloid? 2. I honestly have NO clue what this is. Never seen anything like it. I thought it was nothing, but it seems to have such a defined symmetrical shape... ...

A very successful hunt (for me) in the Toronto area!!!
Monica posted a topic in Fossil Hunting Trips
Hi everyone!!! I had the afternoon to myself today because William and Viola are at day camps this week and my husband was busy, so I decided to check out Mimico Creek (Georgian Bay Formation, Upper Ordovician) by myself for a couple of hours. I didn't make many finds, but the finds I did make were super-amazing (by my standards, anyway ). As I was walking along the creek when I first arrived, I was checking out the wall of rock when I noticed a pattern: After gently prying out the rock, this is what I found: Hooray!!!!!!!!!! My first Flexicalymene granulosa!!!!!!!!!! For those of you who have read my trip reports and ID requests in the past, especially when I first started fossil-hunting in 2016, I always went out hoping to find a trilobite, and today I succeeded!!!!!!!!!! I then spent about an hour mucking about, not finding much, when I decided to hammer a big slab of rock that had some worn bivalves on the surface. Lo and behold, hidden underneath that layer of rock was the most beautiful Treptoceras crebriseptum orthoconic nautiloid that I had ever seen!!!!!!!!!! The bottom part of the fossil doesn't appear to have septal divisions, and it's a little flatter than the rest of the fossil - could it be the living chamber?!?!?! I cannot believe my luck today - this has been my best day of fossil-hunting in the Toronto area in the past 3 years!!!!!!!!!! I'm so excited!!!!!!!!!! I do have to play it cool at home, though - I don't want Viola to be disappointed that she missed out (I haven't yet told her what I did today - it'll be a secret for a while). @JUAN EMMANUEL @Wrangellian @Ludwigia @Malcolmt - I thought you might like to see

Gorgeous Orthoconic Nautiloids (Toronto/Ordovician-Georgian bay formation))
Emthegem posted a topic in Fossil Hunting Trips
Hello to all! Its been a very long time since I've been on here, but my recent trips around the creeks in Toronto, Canada (in the Etobicoke area) have yielded some of my largest and most defined finds of all time, here are some of the nicest Orthoconic Nautiloids I had found yet: Probably the nicest one in my collection at this moment, found almost completely by fluke when I hit a rock with my pick and this bad boy showed up Imprint made by the previous one These last couple would be way nicer, if only I could find a way to get it out of the rock matrix without completely destroying the specimen :/ ... Anyways, it good to be back and hunting this summer after a somewhat stressful finals season. I also have wayyyyyy more stuff that I found such as some unusually large and defined bivalves and tentaculites (maybe?), but I might save those for another time as they definitely weren't as cool as these ones. All were found along river rock deposits In the west side of Toronto (Etobicoke, Humber and Mimico creek) - Georgian Bay formation, excavated using rock pick and chisel.

Hello all! Here are some of my my favourite scenery and fossil pictures from the last few weeks! Decided to hit up some new spots way up in the north end of Toronto along the Humber river - which yielded some very nice shells and crinoid segment (instead of the usual nautiloids). I'm in the midst of getting the weird nautiloid section so stay tuned: Lets kick things off with a couple very pretty shells and crinoids from the north end trip: the 7 shells from the left are Ambonychia, with the two black right shells being Pholadomorpha pholadiformis (I believe). Some crinoid segments on the far right These Ambonychia shells were definitely my favourites of the bunch^ When it comes to crinoids, this is about as good as it gets here in Toronto!!!! Almost nobody finds calyxes here, so this is about as good as it gets!

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...

Hello! It was found in the Georgian Bay Formation - Ordovician period, in West Toronto. It was found after cracking some rocks on the riverbanks of Etobicoke creek. I recently came across a rather peculiar fossil, I initially though it might have been an ammonite, but those didn't exist until much later than the Ordovician period. It seems to be slightly ribbed, with a bit of a spine.

Hello again! Sorry for the constant posts, but I've been finding a lot of amazing stuff recently! Anyways, as the title says, this was probably one of my best hauls ever for a single day! I managed to find over a dozen different nautiloid chunks and was able to extract toooooons of super well defined and complete brachiopods from a matrix piece!! This will be another 3 part post as i have lots of pictures: Here was the full haul for the day, with ruler for reference (notches in cm). Here are some alternate angles of the nautiloids. I going to assume/believe they are mostly, if not all Treptoceras Crebriseptum, but if anyone notices any different species I'd be glad to know! some nice crinoid stem segments, a Pholadomorpha Pholadiformis and Ambonychia plate, and another decent nautiloid.

Hello! Just wanted to show off some VERY nice fossils (by our standards) I found this past weekend in Etobicoke creek right around the border of Mississauga/Toronto! Me and my dad decided to get back in the groove for some fossil hunting and spent a while biking off road until we came across the mother-of-all rock deposits (by Toronto standards). I posted a couple pictures of the big/best finds below, sorry I didn't have a ruler on me for reference so Canadian currency will have to do for those not from Canada: *To make the lives of those outside of Canada slightly easier: 2$ (multi-tone) coin is 2.8cm, 1$ (loon) coin is 2.65cm and quarter (horse) coin is 2.381cm* For the very last one, we were not able to carry them home on our bikes so they were left there - maybe someone from the forums could pick it up for themselves? Let me know what you think of these finds! We were pretty proud for not having done a dig in a very long time. -Em

Another decent haul over the last few days. Bunch of nautiloids and whatnot, a couple mussels. These were my favourites from the last 2 days in the river. This was a biiiiig nautiloid, and after cleaning it I realized there were two of them! wowowowo! (Sorry the picture didn't turn out quite that nice) This is probably one of my highest quality specimen so far, although it did break near the end when extracting it from the matrix.

Wowowow I was very surprised to find all this amazing stuff today at my favourite river bank fossils spot of the Etobicoke creek. I managed to snag a whole lot of stuff today, some Orthoconic Nautiloids, Brachipods and what I believe to be the nicest tentaculite I've ever seen!!! The fossils are from the Georgian Bay Formation and they were found in the broken up "rock fields" next to the creek. This is going to be one of my longer posts, so I will have to split them up into section. The full haul, with the typical estwing 22 ounce rock pick (33 cm from bottom of the handle to the top of the hammer end for anyone who doesn't own one). First lets start with the usual: Them cone boys, aka Orthoconic Nautiloids. I believe all of the following to be Treptoceras crebriseptum.

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...

Hello, I recently cracked open a rock to find one the most pristine and unusually shaped fossils I've seen in a looong time. I predict it might be the edge of a bivalve shell poking out, but I wanted to know what others might have to say about this. It was found in the rock deposits of the rivers in Toronto, Canada, and is part of the Georgian bay formation. Also, only the bottom half seems to be completely crystallized and is translucent, whereas the top is relatively opaque: I am somewhat worried about totally ruining the fossil if I try to further crack into the matrix, as it is Ordovician era rock which is very hard and often results in the destruction of the specimen when trying to clean up the fossils. Sorry for not providing much to go off of . Thanks in advanced for the help! -Em

From the album: Urban Fossils of Toronto (Georgian Bay Formation, Lower Member)
Endoceras proteiforme, found in the Humber river area. Late Ordovician, Georgian Bay formation, Toronto, Ontario. Length is approximately 35 cm long with a nickel shown. This specimen is a portion of the whole fossil that is still to be excavated (it's just so difficult to dig out) and the remaining body of this thing is still there at the site where I got this.© (©)
