||Mussels (Pelecypods) were found in abundance in the Georgian Bay Formation Shale and were found closed up. When you touch a modern living clam they close up due to fright. When they die they open up. This means the fossil mussels were buried alive, and so deeply that they couldn’t burrow out. It also means the surrounding sediments hardened too quickly for them to open up after they died.
