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.

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?© (©)

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.© (©)

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.© (©)

I found these two fossils from Mimico Creek in Toronto, Canada and they both belong to the Georgian Bay formation, late Ordovician. The first one I believe is a Pseudolingula, but I can't really nail it down to a species level. The other is a bryozoan, and I was thinking of Prasopora. What do you guys think? The brachiopod I found in shale, but the bryozoan in a limestone bed with other bryozoas. The brachiopod: The bryozoa:

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.© (©)

Found in Mimico creek, Toronto, Ontario. Georgian Bay formation, late Ordovician. I found this by accident when I first started fossil hunting at Mimico creek back in October 2013.

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.© (©)

Complete specimen of a late Ordovician cephalopod Treptoceras crebiseptum, even with the living chamber intact. The length is appr. 37 cm. From the Mimico creek, Georgian Bay formation, Ontario. Specimen found in shale and my first complete one!! I usually find small fragments of the phragmocone at Mimico creek. Also keep in mind specimens found in shale are preserved squashed, compared to the ones preserved in limestone they are preserved in their original shape.© (©)

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.© (©)

A slab full of late Ordovician fauna of the Georgian Bay Formation of Toronto, mostly containing whole complete Modiolopsis. Found at a collapsed cliff of shale at Mimico creek. Many specimens have crushed parts and their bits of crushed parts got thrown all over the slab, so probably this was a storm turbulence-caused death.© (©)
