I'm a little surprised that I hadn't posted anything regarding some plant fossils I found last fall in Canada. These next few posts should rectify that starting with some humble Algae. The carbon coating on dolostone below is thought to be a fossil algae and was found in the Bertie formation at Ridgemont Quarry, Fort Erie, Canada. The Bertie formation is better known for it's Euryptid fauna but plant material is actually more rare.
This was collected last fall from the Ridgemont Quarry which is kind enough to allow collectors access to their property to prospect for fossils. The Bertie formation is late Silurian (Pridoli stage) in age and has been interpreted as a shallow lagoonal deposit.
