An unknown item from Etobicoke Creek (Upper Ordovician) and a shiny item
Monica posted a topic in Fossil ID
Hello once again! Upon closer examination of some items I recently collected from Etobicoke Creek in Mississauga, Ontario (Georgian Bay Formation, Upper Ordovician), I have found a couple of items I'd like your thoughts on. Item #1: Found on the same rock as a monoplacophoran (Cyrtolites ornatus), the unknown item is tucked underneath some matrix: View of the whole rock: Close-ups of the unknown item: Continued...- 2 replies

Hi everyone! I found this piece yesterday at my new spot along Etobicoke Creek here in Mississauga, Ontario (Georgian Bay Formation, Upper Ordovician). It's a bryozoan of some sort with some crinoid stems on it, along with an imprint that I think is either a Cruziana ichnofossil or a weathered crinoid stem imprint - what do you all think? I've boxed the imprint in red. Thanks in advance! Monica Views of the imprint: View of the other side of the rock/bryozoan: Close-up of the bryozoan:

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...- 25 replies

I was able to get some much needed "me time" yesterday. With all the worries of the world I have been in a foul mood lately, but I am happy to report that my mood has brightened significantly. . There is nothing like crawling around on a road cut, and hunting fossils, to really lift one's spirits! I spent a couple of hours at an upper Ordovician road cut that has been on my list to check out. It is an exposure of the Grant Lake Limestone. Shortly after I arrived, I realized that I was in for a real treat! This particular exposure is more fossil than limestone. Brachiopods are everywhere! Vinlandostrophia dominate the exposure; with Hebertella coming in a close second. Other brachs are also found, but less abundant. Orthoconic nautiloid fragments are frequently found and bryozoan encrusting is a common sight. I also found a few gastropods, and one trilobite piece that I am excited about. Unfortunately I did not take pictures in the field. It was a conscious decision. I just wanted to enjoy my time, relax, and focus on the hunt. I'll get some next time as I will definitely be going back. I did take a few pics of my better finds at home. Enjoy! First up are the Brachiopods. I found some nice whole Vinlandostrophia, and Hebertella, and what I think is Rafinesquina ( @Tidgy's Dad ) . I also took home a few single valves for study of the internal structure. I think with a little bit of clean up these will look great! I was happy to find some orthoconic nautiloids. They have been sorely lacking in my collection. I will have to research what species are found in this formation to come up with an ID. I have a few ideas, but need to confirm. Here are a few gastropods and bryozoans. I can't resist the alluring whirls of a gastropod. They seem to be uncommon in the areas that I hunt so I grab them whenever I see them. I believe these are new species of bryozoa that I will be adding to my collection. Which is exciting! Here is a tril-o-bit that I found. I'm very happy with it. Typical trilobite fragments from this area are not usually identifiable. Except to say they are possible trilobite pieces. This is a cephalic doublure of an Isotelus. Thanks to @piranha for help with the ID. All in all it was a great time. I got to relax a bit, forget my troubles, and brighten my mood. I also added some nice pieces to my collection. It was a good day!

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...

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

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...

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):

What's your take --- are these real? Considering purchase. Details: "Selenopeltis buchii trilobites", 45 x 35 cm (total size), Paleozoic, Upper Ordovician, discovered in Morocco. -
Unknown item (sponge?) from the Credit River in Mississauga, Ontario
Monica posted a topic in Fossil ID
Hello there! Last month, I visited the Credit River in Mississauga, Ontario, Canada (Georgian Bay Formation, Upper Ordovician) to look for some fossilized corals. In addition to a bunch of weathered colonial rugose corals, I found an item that I think is something, but I'm not sure what - perhaps a sponge? Here are some photos of it: Side view - dry: Top view - dry: Top view - wet: Thanks so much! Monica- 10 replies

Need help with identification. I have a pretty strong idea that this is a weathered section of a cephalopod but I would like to be certain. Your feedback (as always) is appreciated. :)-

Hello there! Well, I tried to take Viola out for a little fossil hunt by Mimico Creek in Etobicoke, Ontario (Georgian Bay Formation, Upper Ordovician) this afternoon because when I checked the forecast this morning it looked like it was going to be ideal fossil-hunting weather - a mix of sun and cloud with temperatures in the mid-20s Celsius. When we arrived, however, it began to rain - we toughed it out and came away with one piece before it began to pour and we called it a day. I was disappointed since I was hoping to spend a few hours there, but the one piece we took home looks like it might have a graptolite on it, which is quite exciting since I have yet to find one in my local haunts. Please check out the photo below and let me know what you think: Thanks in advance for your help! Monica

Hello there! I was inspired by @markjw to check out the Credit River here in Mississauga, Ontario (Georgian Bay Formation, Upper Ordovician) because where I normally hunt there are typically no corals and I'd love to add a couple to my collection. Consequently, I went out for about an hour this morning before the family got up in order to try my luck, and I'm happy to say that I was successful!!! Based on information provided by @FossilDAWG in other threads here on TFF, I think all of my colonial rugose corals are Favistina calcina - here are photos of three of my specimens: Specimen #1 - side view: Specimen #2 - top and bottom views: Specimen #3 - top and bottom views: more to come...

Hello everyone! On Monday, I found a beautiful Treptoceras crebriseptum orthoconic nautiloid in a huge rock at Mimico Creek in the Etobicoke/Toronto area (Georgian Bay Formation, Upper Ordovician). It has been suggested that I might have a complete specimen, so I was hoping that someone out there might be able to let me know if this is the case or not. Here are some pictures... Whole specimen: Close-up of the base of the specimen (specimen has been turned over) - note that it is smoothly rounded and shows no septa - is this the fossilized living chamber of the animal? Close up of the tip of the specimen - note that it seems to end before the rock edge - is this the very tip of the animal? Close up of the piece that shattered off the tip of the specimen - note that it also seems to end before the rock edge: Thanks for your help!!! Monica

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- 63 replies

I found this several years ago in Kentucky near Maysville, which, based on this map, is in the middle to upper ordovician. It was probably around 50 feet down. All I have is the tail. Probably not enough to identify, but any information would be appreciated. I couldn't find a measuring device, but I will post a picture with one as soon as I do. It is about 8 1/2 inches long, or 26 1/2 centimeters. Map is upside down. I have the fossil on hand for any clarification/questions.

First off, I don't know anything about paleontology. I found this fossil in Nicholas county Kentucky. It was about at the C in NiCholas county on the map. Sorry it's upside down, but Nicholas is 2 above bracken, assuming picture orientation. The fossil was 6-10 feet down. The first layer of fossils went down about 5 feet, maybe more, and we're tan and sandy. Below this layer was a gray layer, and this was several feet into that. Also, don't have enough file space to do enough pictures for inches, but it is about 11.5 centimeters long, or 4.53 inches.

Today I drove the great distance of 10 whole miles to collect along a creek. I have known about this location for many, many years but did not know the exact location. I first read about it in the old 1964 Edition of "Fossils in America" written by Jay Ellis Ransom. Though i was only 3 years old when this book came out, it must have been a great edition for any fossil collector in the United States. It does it's best to give the location of fossil collecting sites in every state by County. For the fossils that I was after today, Tentaculities oswegoensis, it mentioned that they were found in Kendall County, and this area is the only location that this species is found at. As luck would have it, I received an e-mail from a fossil buddy who mentioned that he had been out there collecting some and he was able to pin point the location for me. It was along a nice creek, but due to the constant rain that we have been receiving, the creek was high and running fast, but I was able to collect a few examples. I do not know if this is a location that I will visit again, maybe when the creek is down, but it was very close to home and I did have fun. These fossils are supposed to be Upper Ordovician in age and from the Maquoketa Group (446-440 MYO) @Peat Burns / @Tidgy's Dad / @Monica you might enjoy this post. Here are some pictures of the creek and the exposure- Here are some pictures of my finds, first as I picked them up and later with a 1 cm scale cube. With Scale Cube- There are also brachiopods to be found there, here are a couple examples.

crinoid stem, ichnofossils, and maybe a hyolith at Etobicoke Creek?
Monica posted a topic in Fossil ID
Hi all! Yesterday afternoon I visited my local haunt (Etobicoke Creek, Georgian Bay Formation, Upper Ordovician) with the kids, and I found a few items that I'd like to show you: Item #1: long crinoid stem - any ideas as to its identity? Item #2: big piece with ichnofossils - item circled in yellow is ichnofossil "a" and item circled in orange is ichnofossil "b" Item #2a: ichnofossil "a" top view Item #2: ichnofossil "b" top view Item #2: ichnofossil "b" side view Item #3 top: two views of a mineral stain that has the shape of a hyolith - what do you think? Item #3 bottom: crinoid columnal impressions (I think!) so it is fossiliferous rock (I think!) so perhaps the specimen above could've been a hyolith??? Thanks as usual for your help!

ID for dark, flat fragments in Upper Ordovician deposits
David Fankhauser posted a topic in Fossil ID
These are not the largest specimens of this broad flat smooth dark fragment, but you can see some fragments in this sample collected from 9 mile creek just east of Cincinnati. Yes, that is a gorgeous pygidium, presumably from Flexicalimenes? -
Hello! I just came across almost a complete hypostome and a larger wing of the mouth line on a smaller hash plate. Didn't know it until I broke down the matrix. The more I chip away at the plate the more minor trilobite pieces I am finding...which is not unusual. Is there any suggestions on how to categorize and store these??? Sorry for the snarge picture.... Still need lighting in my new manpad.

Hello again! The weather was warmer today, and since I had the kids to myself all afternoon while my husband went to see a movie with a friend, I decided to take the kids out once again. We first tried to do some collecting at Mimico Creek but were unable to because (1) the water was running too high, and (2) they've been doing some construction work around there which prevents us from getting close to our hunting spot. So the kids played at a nearby park for a while, and when I suggested that we check out Etobicoke Creek again, they were all for it (even William!). There was no ice this time, thank goodness, and what follows are just a few pictures of what I found - enjoy! I hope you're all having a wonderful holiday! Monica Orthoconic nautiloid (Treptoceras crebriseptum) chunk: Bivalve (Ambonychia radiata): Brachiopod (Sowerbyella sericea) positive and negative - the positive is just under 2cm long at the hinge line while the negative is just over 2cm at the hinge line (I'll tag @Tidgy's Dad just because I know how much he loves brachiopods ): Viola showing off one of her finds (another T. crebriseptum) with William joining in on the photo:

Hi all! I decided to take the kids for a quick hunt at our local spot along Etobicoke Creek before going to see "Mary Poppins" in the afternoon - enjoy the photos (and enjoy the fact that you weren't out there with us - it was SO cold!!!). The rocks in this area are from the Georgian Bay Formation and are from the Upper Ordovician. Monica The kids spent more time breaking ice with rocks than actually fossil hunting (some of the chunks of ice were quite thick!!!): Viola did take some time away from her ice-breaking duties to check for fossils - she found a cute little orthoconic nautiloid: I also found a small chunk of orthoconic nautiloid with the siphuncle visible: I found two pretty nice crinoid stems for my area as well: Additionally, I found a nice chunk of rock with some ichnofossils in it - any ideas as to what made them? Perhaps @abyssunder and/or @piranha and/or @JUAN EMMANUEL can chime in... Finally, I found a rock with some interesting stuff going on within it such as some brachiopod imprints and what appears to be a tabulate coral. This is interesting because I don't think tabulate corals are found in the Georgian Bay Formation - I guess it's a traveler? Any ideas as to the identities of the specimens in the rock, or are they too water worn? Maybe @Tidgy's Dad and/or @Peat Burns can help...

I've been sifting through a bucket of dirt I collected on my last dig in Cincinnati. I've come across these two pieces that has me scratching my head. Are they ammonites, snails, arms of a Isorophus? Not the most glorious finds but two that I am having some trouble while cataloging. Thanks all!
