Large Rock with Bivalve fossils

Recommended Posts

This specimen measures about 22.5cm in length and 14cm in width. I found it about 9 months ago on the riverbank along Joshua’s Creek in Oakville, near the tip of the Georgian Bay Formation that meets Lake Ontario. Been really busy the past few months, so haven’t had time to post it until now. Can anyone identify what Fossilized Bivalve species are present on the Rock?

Not much more than impressions I'm afraid.

Without evident ornamentation of the "dorsal" side, it is hard to say, but these steinkerns seem to resemble orthid brachiopods.

I agree - very worn internal molds of orthid brachiopods.
