Submitted by Vicki Lais on Sun, 11/24/2002 - 11:00pmThis months trip was to a graptolite
site in Bibb County, Alabama. This is the Athens Shale formation
(Ordovician age). Graptolites are found from the Cambrian to
the Carboniferous, and are an extinct group of Paleozoic colonial organisms.
They are usually found as thin carbonized films in various shales or limestones.
