Hi guys so I have this Hebertella occidentalis specimen I collected yesterday from the Credit River at Streetsville, Mississauga, Ontario, which belongs to the Upper Member of the Georgian Bay Formation. Do these look like predation marks? There are also what appears to some crystallized grains inside these marks and I think they could be some sort of calcite. Sorry for the noisy grain of the image, but I hope this will help.

I've received a couple nice Upper Ordovician additions to my collection courtesy of @JUAN EMMANUEL and I'm finally posting them now... (Thanks Juan!) First, is this Tentaculites or Cornulites? I wish I could get better pics. Manitoulin Fm, Hamilton, ON.

Hi guys, I visited Mimico Creek 2 days after the Canadian Thanksgiving this October which also happened to be a really hot day, which was perfect for exploring. During my time hunting the Georgian Bay Formation of Toronto I would come across these exposures that look “folded”. Does anyone happen to know as to what this really is? Here is a pic I took on that trip I mentioned to show as an example. I would find the same distortion in other parts of Toronto, not just in Mimico Creek, but also in places like along the Humber River and Etobicoke Creek.

Hello there! Yesterday, Roger @Ludwigia dropped by for a visit, and we spent the day together checking out my local haunts with Viola. The day started with some coffee and brownies, as well as lovely German gifts from Roger: a Macrocephalites sp. ammonite for Viola (I don't have a picture of it because it's up in her room) and a Brasilia bradfordensis ammonite with a hitchhiking bivalve on the back of the matrix for me!!! See pictures below: We then piled into my car and drove to our first spot: Mimico Creek in Toronto. The fossils here are from the Georgian Bay Formation (Upper Ordovician). Here's a picture of Roger and Viola checking out the site... And one of Roger wielding his hammer... Since I'm still nursing my "fossil elbow", I didn't want to hammer anything; instead, I scraped into the wall of rock and I'm happy to say that I found a couple of sweet little bivalves: one with its two valves partly open (too bad that it's not complete) and another one with some nice ornamentation visible on its shell... @Wrangellian - what do you think? Roger did a little exploring and found some fossiliferous rock further up the wall - I collected two fairly big pieces of this type of rock and, lo and behold, they contained a bunch of brachiopods and their imprints (along with some other goodies)... @Tidgy's Dad - I thought you might like to see them

Flexicalymene granulosa, Mimico creek, Toronto, Ontario. Georgian Bay formation, late Ordovician. Complete specimen still embedded in the shale. Will need prep work to be exposed. I found this one at a collapsed cliff of shale at Mimico creek. I found some flexi's this summer at Mimico creek but usually whole specimens start crumbling apart the moment I try removing the matrix around the specimens.© (©)

The first major event to wash the creek was the nasty February winter we had in the city. Let's recall the ice that melted and went down the creek back in March. Then fast forward to June. I believe the city had rain during the first 2 straight weeks of June in which I remember seeing many creeks being flooded continuously for several days. Then gradually the rain stopped, I waited for some time to give the creek's water level to drop low again, and that's when I set off to visit the ravines of Mimico Creek.

cheeseburger posted a topic in Fossil ID
I found the first two of these pictures in the river bed of Etobicoke creek, Toronto, Ontario, Canada, and the final picture is of one I found at the lakefront of marie curtis beach park. I have tried looking online and read they might be from ordivican? but I really have no idea! new to fossiling -- but definitely interested in learning more!

Hello, I want to put together some pics of some of the reef material that I have found in Streetsville, Mississauga, Ontario on the banks of the Credit River. It is now winter and I am missing the warm days in which I can go and wade in the warm waters of the river for fun. I just want to compile and share some specimens that whose photos I have not shared with. All the fossils belong to the Georgian Bay formation, Upper Member, which is late Ordovician in age. First is the common coral that displays an enormity of growth forms, Favistella alveolata (Goldfuss, 1826).

Hiya I just found this tooth it is 4cm long on the earth of a house Reno. My guess was a bison but we are in Toronto Canada not many bison here. How old is it? What mammal is it? Please help solve the mystery

I found this crinoid head on a limestone that belongs to the Georgian Bay Formation, late Ordovician, today at the Humber River in Toronto, Ontario. Is this crinoid a Cincinnaticrinus or a Glyptocrinus? I have included a nickel for size reference.

A tergomya mollusc that can be easily found in the Humber Member of the Georgian Bay Formation in Toronto. This one is set on a limestone hash plate dominated mostly by pelycopods. On a personal experience I have come across more Cyrtolites specimens than gastropods at Mimico Creek. Reference: Ontario Department of Mines. The Stratigraphy And Paleontology Of Toronto And Vicinity.

Lingulichnus verticalis (Hakes, 1976). The elliptical shaped and concave burrows or holes were made by a linguloid brachiopod burrowing in the sediment. I took this plate home as I have never seen so many Lingulichnus burrows on one plate. Rock is limestone and was most likely mud before it lithified.
