While doing yard work I came across this rock sitting between my house and the neighbors. After walking past it a few times I flipped it over to find this gastropod, which is the largest and most well preserved I've found so far! I haven't found a genus or species yet, so feedback is highly appreciated, but I wanted to share it as a reminder as to what you can find even in your literal backyard

Here's something I found a few months ago. There are lots of bits of brachiopods which seem to have been preserved in their original perfect shape instead of the casts I usually find. It's what's on top of them that interests me. It looks like it could be a trilobite cephalon, if that's the case then the closest match I could find was Ceraurinus sp. I'm pretty sure I saw something to do with a crinoid that looked similar though I haven't been able to find it again. Any other ideas?

From the album: Urban Fossils of Toronto (Georgian Bay Formation, Lower Member)
Conularia formosa (Miller and Dyer, 1878). Georgian Bay formation, Lower Member, Late Ordovician. Found along the Humber River of Toronto. This specimen was found when I was smashing some of the limestone of a bedding and this popped out. This is the only Conularia formosa I have ever found along the Humber River.© JUAN EMMANUEL

Modiolopsis ovata (Conrad, 1842). Georgian Bay formation, Humber member, Late Ordovician. Collected from the Humber River area of Toronto, Ontario. The body had been calcite replaced and was found in the shale. There are also flecks of pyrite which are the gold coloured marks on the right side.- 1 comment

Hi there, new to this site. Everyday me and my baby go for a morning stroll in the gulf of the etobicoke creek and I marvel at the shale sediment layers on the west cliff in between Eglington & Burhamthorpe. Being a curious scientist I tried googling it but came up short. The only thing I could written about it's formation was on this site and I've been Googling a lot of Latin words, seeing as how I'm new to the fossil world. Can anybody help answer this question? I'm amazed that the creek isn't a protected site if the shale is indeed over 460 million years old and has fossils!! Mind blown! I can't wait to take my baby fossil hunting when she's older!! Anything to instill the love of the great outdoors! Any tips on that would be greatly appreciated as well! Many thanks

Here is a rock I found over the summer but I am continuing to clean. With the tools I have and the rock's size it is quite difficult to get dirt out of the small bits but it's looking much better. I found this very early in my fossil collecting hobby so at the time I didn't know much about what it was, but I now know that it's crinoid bits (perfectly obvious to me now of course, but it's part of the experience). One thing that's cool is when I first uncovered it, it looked like the whole one side had the bits, but you can see along the middle there isn't as much debris as the sides, which leads me to think that the rock represents 2 separate crinoids, as opposed to one big scattered one that covers the whole rock like I initially thought. I will continue to remove dust so I'll post again if anything interesting shows up!

Gastropods (Hormotoma?) and bryozoans (maybe), Upper Ordovician

A couple of finds at Mimico Creek (gastropods, ) and Lake Ontario (bryozoans? coral colony?) ... Thanks for any assistance! Camille -
Some recent Upper Ordovician finds at Mimico Creek, Toronto
Rogue Embryo posted a topic in Fossil Hunting Trips
First, if anyone in the Toronto area is interested in going fossil hunting along Mimico or Etobicoke Creeks, I'd welcome the company! Before I get to a couple of better finds, I'm curious to know what the black fragments are below, which I often find embedded in the shale. Can someone please give me a clue about these? Some orthoconic cephalopods: The next two are the same fossil from different perspectives: Some bivalves: Bryozoans: Cheers, Camille -
Found this lovely pair of bivalves in Mimico Creek over the weekend and hoping to get some help on ID. It looks like either Colpomya or Cymatonota, based on images I've seen. Any ideas in this? Camille

Maybe I'm imagining patterns. Coral? Geological process? Found along Lake Ontario, among other whitish rocks from elsewhere, most very fossiliferous, arranged along the shore.

Wondering whether this is a bryozoan colony or a coral. In the detail, I noticed a honeycomb pattern, but I think both bryozoans and corals can have such a pattern. Thanks. Camille

Trip to Etobicoke Creek (Georgian Bay Formation, Upper Ordovician)
Rogue Embryo posted a topic in Fossil Hunting Trips
My first visit to Etobicoke Creek in several years yielded a few finds, but will search other spots along the creek in the coming weeks. Some cephalopod fragments: A "misshapen" cephalopod? An outline on a perfectly flat rock: Not sure what these are; not much detail: Two of the better Pholadomorpha pholadiformis specimens: Camille- 2 replies
