Yesterday on April 24 I decided to go and visit a place in Mississauga, Ontario called Streetsville which used to be a township of its own before being joined to Mississauga to form the City of Mississauga. I took public transportation to get there and it took me about 1.5 hrs to get there. I went to the Credit River near Streetsville and explored the banks. I had trouble finding a natural exposure as all I was finding were banks with worn out rocks and silt. The river's bottom does not have the same clarity as the Humber River in Etobicoke as I could not see the shale bottom of river. All I was seeing at the Credit's bottom were worn out rocks, algae and silt. The river was also wider than the Humber and in some places it seemed deeper as well which made me think twice about crossing to reach this natural exposure I found. The banks mostly had worn rocks but some nice material can be found. I was surprised at the fauna I found. The rocks are still part of the Georgian Bay Formation but the fossils are completely alien to my eyes. They were nothing that I usually encounter at the Humber River or at Mimico Creek. The place was littered with small coral bits and there lots of what appeared to be Tetradium bits. There also many brachiopod hash plates around. This hash plate here has a piece of coral at the bottom along with many brachiopod bits. There were some things familiar to me like that hash plate of bryozoans and I only found one cephalopod fragment. Where I usually hunt cephalopods are very common to find in Mimico Creek and at the Humber River. There were also these odd trace fossils lying around.

Hello once again! Viola and I went to a new location for a little fossil-hunting this afternoon, and we think that she may have found a rough-looking trilobite - what do you think? We found it by Mimico Creek in Toronto (Georgian Bay Formation, Upper Ordovician). It's in a massive piece of rock so if it is indeed a trilobite then we'll have to find a way to cut the rock to save only her little treasure Thanks in advance! Monica

Hi guys I just wanted to share some of the more interesting and unusual cephalopods that I've managed to amass over the past and nearly 4 years of hunting along the creeks and rivers of Toronto, Ontario. I was cataloguing them on my computer and I figured out that I might as well share them. The ones below all came from Mimico Creek. All the fossils belong to the Georgian Bay Formation, and are Late Ordovician in age. A Treptoceras crebispetum (author unknown) covered in an unidentified bryozoan. Length is around 15 cm. My first complete specimen and the same species as above. Complete ones like these found in the shale are often squashed. The body chamber is intact and the specimen approaches nearly 40 cm in length. The smallest complete specimen of the species that I have. This has the body chamber. Length is approximately 10 cm.

It has been reported that complete specimens of this species is rare to find in the formation. The Royal Ontario Museum is said to contain many partials and most come from the former Don Valley Brickyard in Toronto. This specimen was found in Mimico Creek.

On Monday Sept. 12 I had some chances to explore zome of parts of the Humber river in Toronto, Ontario, because soon the weather will turn colder and the river waters wont allow exploration. I was walking at a certain part of the Humber river above Bloor St. when I noticed that I could actually see the river's bottom which is made of up shale bedrock. I decided to check the banks from the water. The pictures below were taken when I was in the middle centre of the river where the waters reached up only knee high. Below Bloor St. the water got mucky and there are several marshes lining up the banks of the river. I didn't see any exposures of the Georgian Bay formation at this part and instead I chose to walk north. In addition to discovering the shallowness, I also saw a potential exposure of the Georgian Bay formation, although the exposure could use more erosion to remove all the debris. The area where I discovered the exposure is in a park where all the banks got bulldozed several decades ago to control erosion, which covered most exposures at this park. The exposure revealed limestone layers interbedded with shale. Some of these layers got thicker than 15cm. One limestone layer was fossiliferous which I thought could make some nice hashplates. This limestone layer contained gastropods possibly Hormotoma (?). I have discovered a tiny gastropod hash plate once in Mimico Creek back in 2014 near the mouth. There were also plenty of pelycopods in the layer. I could not recall finding any cephalopods in the entire length of the exposure. A piece of gastropod hash plate I took home. The shells are preserved as internal molds. A Cyrtolites ornatus. I found 2 of these and this was the one I took home. A piece of ramose bryozoa.

Conularia formosa (Miller & Dyer, 1878). Found in limestone at Mimico Creek, Toronto. Late Ordovician, Georgian Bay formation. Species unknown. Negative cast. There are pelycopod molds surrounding the specimen. Note: I was talking to David Rudkin (Assistant Curator, Invertebrate Paleontology) at the ROM rock clinic on Dec. 10, 2015 and showed him the specimens of Conularia and he pointed out that the species that can found in the Georgian Bay formation is C. formosa.© (©)

This week I got my monthly TTC Monthly Metropass for the first time ever and so with this card in my wallet I was excited that I had unlimited freedom to use the transit to go wherever I want in the city of Toronto for the whole September. Yesterday, while travelling with my card in wallet in Scarborough after finishing an assessment, I came across a creek right at Progress Drive and went down to explore it, in hopes of coming across the Whitby formation. I had seen bits of information regarding outcrops of the Whitby in Scarborough on the net, and I took this opportunity to explore as I live far away from Scarborough. I went down on a driveway I found behind a building and descended below to the bottom. From the edge of the creek I saw no exposures of the Whitby formation but instead saw outcrops of sand, a bit similar to what I saw at the Don Valley Brickworks. Some of the outcrops' bottom were ridden with overgrowth, so I chose the one that had the least, which was this one. The highest point of this outcrop would be around three storeys high and streches for several metres. There's also a substantial sediment material that has fallen off at the bottom and the vegetation on the bottom isn't as thick.

Fossil driftwood from an unnamed tributary that feeds into Highland Creek. Top photo is top side, bottom is the bottom view. Scarborough formation, Early Wisconsinan, Pleistocene. Found on an outcrop of the creek near Progress Drive, Scarborough, Toronto. Finally! I determined what the outcrop was. Does anybody else in the forum have hunted or hunt in the Pleistocene of Scarborough?© (©)

I spotted this flat orthocone on a platform of limestone at a park beside the Lake Ontario. The limestone on which the fossil is set on was hauled in from Manitoba (from what I heard) and is used in many created and developed parks here in Toronto. I also heard that this limestone is Ordovician, which is kinda true judging from the fossils that I've observed on the rocks (ex. Isotelus fragements, some Ordovician strophomenids, some Favosites corals, only straight-shelled orthocones). Could it be an actinocerid and could these limestones be the ones that originate from the Tyndall limestone?

Little ripple marks caused by the gentle currents on the shallow late Ordovician sea floor of Toronto. Georgian Bay formation, Humber member(?), Humber River area, Toronto, Ontario. Limestone slab, the coin is a quarter at the bottom for scale. Hmm, I'm beginning to decide if I should have taken this home with me today. Also at the bottom are two clam negative casts: a Whiteavesia and a Modiolopsis.© (©)

Ever since summer vacation started I have been free to explore the Humber River area and made frequent hunts there in the late Ordovician rocks of the Georgian Bay formation of the city of Toronto. I realized that I did not have a substantial amount of material from this location that I discovered by accident, and so I decided and started to invest some time in exploring this particular location. Last year I only made seven visits, but I did not hunt productively, as I was in my first year of fossil collecting and as a result I had very little material from this location. I knew this location that I accidentally stumbled on had a lot of potential, considering that a great deal of the original exposures are still intact and there were few disturbances done by tractors, whereas compared to Mimico Creek a great deal of the original and actual exposures have been buried. I made three different visits, the first trip I believe was last week and the third today. On the first trip I only took home three specimens, but gradually as I hit the third visit the amount of my finds increased. On the first trip I only found at least three materials. The first thing that I discovered was a Treptoceras crebiseptum specimen. What made me surprised with this specimen was that this specimen actually had Cornulites sp. attached to it. I've never seen something like this in Mimico Creek. There were tubes of the worm attached on the orthocone and also the orthocone was not squashed flat because of the nature of the shale it is in. Actually, I noticed that certain shales in this location did not squash completely flat the orthocones that get preserved in them, which is very different from Mimico because most of the orthocones I find in Mimico shale are compressed. Sorry if I didn't carry any macro lenses and a good camera to capture the Cornulites, the location's flood from a recent rainfall made the place really mucky and wet and the flood waters were just starting to recede. Out of all the Treptocerases that I discovered on that trip, this was the only one that I decided to take home.

A second and more detailed photo of the modiolopsis slab. This one shows a little bit more detail, hopefully. Also, it appears that this thing is not full of modiolopsis as I first concluded, but rather it is full of Whiteavesia pholadiformis. There is also a Cymatonota lenoir, and it appears to me that there is only one specimen of modiolopsis, which would be M. concentrica. Dime shown for scale, and Georgian Bay formation, Mimico creek.© (©)

Zygospira erratica. These two are set on a limestone hash plate with an orthocone to the left. Both are the same species and have an obvious sulcus. Mimico creek, Toronto, late Ordovician, Georgian Bay formation. Edit: I also have found a massive slab of limestone that had a death assemblage of these brachiopods . I forgot to take photos though , and I'm not sure if the slab is still there.© (©)

This forum looks great. Happy to be a part of it now. I am interested in fossil hunting in Toronto and the surrounding area. Fossil hunting was one of my activities growing up in Oshawa, ON. Now I am getting back into it as an adult and looking to get more education from it.

Is this trace fossil a rusophycus or something else? I also wonder what animal could've made it because I doubt it that any trilobite could have made it. Late Ordovician, Georgian Bay formation, Mimico creek, Toronto, Ontario.

I made two trips to a place at Mimico creek where a cliff of bedrock collapsed recently and ended up exposing a good amount of fossils. The first trip was on this Wednesday and the other was on today. I mostly found Ordovician bivalves to spice up collection, because my collection lacked pelycopods. The recent rains here in Toronto were the reasons why the bedrock cliff collapsed. And I have to say, the debris that fell was productive!! I ended nicknaming the spot 'Bivalvia Cliff '.

I just wanna share this cuz I never found an endoceras this big before, which is kinda special and unique for me . I was out fossil hunting at the Humber river area here in Toronto with a good exposure back on Saturday and I came across this big phragmocone part sticking out of the bedrock. It was tiring having to dig it out. Siphuncle sticking out Dug out.
