erose Posted May 20, 2019 Share Posted May 20, 2019 Bivalve. Some type of elongate clam. Just the outline is left and maybe a little if the thin shell along one edge. Link to comment Share on other sites More sharing options...
bethk Posted May 20, 2019 Share Posted May 20, 2019 The rock layer underlying Toronto is late Ordovician (Georgian Bay Formation). Not sure what this is but thought the time period might help. Link to comment Share on other sites More sharing options...

Monica Posted May 21, 2019 Share Posted May 21, 2019 I agree with the others - they are definitely bivalves. To me they look like they could be from the family Modiomorphidae, which includes genera such as Cymatonota, Ortonella, Modiolopsis, Colpomya, and Pholadomorpha (all of which can be found in southern Ontario). Congrats on the finds! Link to comment Share on other sites More sharing options...
