yhwhismight Posted October 16, 2021 Share Posted October 16, 2021 Found in Durham, Ontario, Canada, in limestone. Looks like some kind of shell, but am unable to find anything similar online. This specimen was loose but there are others nearby embedded in the limestones. Link to comment Share on other sites More sharing options...

Kane Posted October 17, 2021 Share Posted October 17, 2021 Pentamerids can be fairly abundant in your area, which is situated in the Middle Silurian (Guelph Fm).
