What species of Orthocones and Coral are these?

[jeffln]

I found this buried in the water in Joshua’s Creek, Oakville. This giant rock containing many coral fossils and a couple of Orthocone fossils also. I’m certain the fossils are Ordovician in age. Measurements are 30cm in length and 19cm in width. Can anyone help with identifying the Orthocones and Corals down to species pls? This is my biggest find yet, so excited to hear everyone’s opinions!

Which Oakville?  

Oakville, Connecticut, USA?

Alabama? Washington? California? Indiana? Iowa? Michigan? Maryland? Michigan? Missouri? Tennessee? Texas? Virginia?

Oakville, Manitoba, Canada?

Oakville, Ontario, Canada?

 

Please be more specific when giving locations of your finds.

This seems comparable to Treptoceras crebriseptum.

I agree with Kane on the nautilus, but I'm not even sure if you have any corals there at all. The poor and weathered preservation leaves room for doubt. Maybe bryozoen? I see a few brachiopods anyway.

I have to agree with Ludwigia. I’m not seeing much in the way of coral, looks more like bryozoan to me, but the weathering makes it hard to be sure.

Geisonoceras tenuitstriatum?

Just something I remember seeing, Kane has a considerably better option.

Wrong formation, I think.

These remind me of the rocks of the Upper Member of the Georgian Bay formation along the Credit River in Mississauga, Ontario. I think the same member is exposed along down river at Bronte Creek below the Queenston formation in Oakville. Those types of bryozoans are very common in certain beds in the Upper Member along the Credit River (I forgot what species they are but I can check my notes as I have given away plates of similar bryozoans to other collectors in Canada). And the Treptoceras crebiseptum in said beds are not that common compared to the Lower Member of the Georgian Bay formation.

Thanks a bunch. I found your insight really informative and fun to read! Can't wait to find out what species of Bryozoans I have.

Your bryozoans MIGHT be Rhombotrypa quadrata and Constellaria polystomella.
