Monica Posted July 6, 2020 Share Posted July 6, 2020 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... 12 Link to comment Share on other sites More sharing options...
Monica Posted July 6, 2020 Author Share Posted July 6, 2020 Now for everything else... Bivalve - is it possible that the protrusion is evidence of the siphon? I know it's a long shot but there's no harm in asking! Edit: Apparently bivalves didn't develop siphons until the Mesozoic, so this must not be evidence of a siphon. (information from https://www.bgs.ac.uk/discoveringGeology/time/Fossilfocus/bivalve.html) Nice gastropod with a nice monoplacophoran: Branching bryozoan: SO MANY GASTROPODS!!!!!!!!!! I was so excited to find these - I think I yelped out loud when I saw them!!! The red circle shows a positive/negative of the same gastropod: Monoplacophorans (the one on the left is not complete, but I think the other two are complete): Cornulites flexuosus: That's all - thanks for looking!

Ludwigia Posted July 6, 2020 Share Posted July 6, 2020 It sure is nice to find something different isn't it? Good to see that your explorations have borne fruit. 1 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

connorp Posted July 7, 2020 Share Posted July 7, 2020 Very nice finds! There really is nothing more exciting than finding a new spot, and doubly exciting if it's actually productive. 1 Link to comment Share on other sites More sharing options...
FossilNerd Posted July 7, 2020 Share Posted July 7, 2020 Congrats on the new site Monica! I see why you were excited about the gastros. I really like the positive and negative that you have circled. I would have that one out on display for sure. 1 The good thing about science is that it's true whether or not you believe in it. -Neil deGrasse Tyson Everyone you will ever meet knows something you don't. -Bill Nye (The Science Guy) Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted July 7, 2020 Share Posted July 7, 2020 T'riffic finds, Monica. Love the gastropods and most of all the Cornulites. Great that you found such a productive new site. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Emthegem Posted July 7, 2020 Share Posted July 7, 2020 That cephalon is really nice! And those gastropod shells are spectacular! We don't get as many gastropods down here either so that's a superb find 1 - Link to comment Share on other sites More sharing options...

I don't find many gastropods in my area, and they're usually water worn, so these were such wonderful finds for me!!! Thanks for the congrats! 1 hour ago, Tidgy's Dad said: T'riffic finds, Monica.

I love the Cornulites, too - such a dainty little organism 27 minutes ago, Emthegem said: That cephalon is really nice! And those gastropod shells are spectacular!

Monica Posted July 15, 2020 Author Share Posted July 15, 2020 Thanks, @ConnieJFerrante and @erose! I visited my new site again on Monday - here's what the small exposure looks like: And here's a picture of a high-spired gastropod in situ: I didn't find as many trilo-bits this time around, but I did find my first itty bitty orthoconic nautiloid: (It looks like the negative of the specimen, but it's actually the positive.) And here's a pretty nice imprint of a large bivalve: More to come... 6 Link to comment Share on other sites More sharing options...
Monica Posted July 15, 2020 Author Share Posted July 15, 2020 Here's a chunky bryozoan with crinoids on it: Here's a close-up of the bryozoan: A rock with a nice monoplacophoran on its side along with an unknown item (I'll post photos of the unknown item in the "Fossil ID" section): 5 Link to comment Share on other sites More sharing options...
Monica Posted September 6, 2020 Author Share Posted September 6, 2020 Hello once again, everyone! Yesterday afternoon I visited this site once again, and apparently it was a cephalopod kind of day! I found a few Treptoceras crebriseptum orthoconic nautiloids, including this one which appears to be quite complete (it's the first one I've found that extends almost to the very tip of the apex!): And I found my first piece of Endoceras proteiforme!!! It came out in three chunks, and is quite flakey, so I'm going to have to look into stabilizing it after gluing it back together - any specific suggestions re: stabilizing it would be much appreciated!!! Thanks for looking! Monica 9 Link to comment Share on other sites More sharing options...

The almost-to-the-tip nautiloid has already been glued back together (if the lighting is okay when I get home from work tonight I'll take a picture of it then), and I think we're going to glue together the Endoceras chunks this evening, followed by "painting on" a paraloid-and-acetone solution over the weekend - hopefully it goes well! 1 Link to comment Share on other sites More sharing options...
Monica Posted September 17, 2020 Author Share Posted September 17, 2020 Hey Roger @Ludwigia Here are a couple of photos of the almost-to-the-tip nautiloid glued together: Do you think it's Treptoceras crebriseptum? I'm assuming it is since that's what I usually find, but the lack of visible septa is throwing me off. I went back to my site on Saturday. I didn't find anything terribly exciting, but I did find some fairly complete bryozoans - here are some photos of one of them: I plan on gluing these pieces together when I find the time to do so. 3 Link to comment Share on other sites More sharing options...
