I have consulted several publications on these formations and yet I am a bit stumped on these last ten fossils. The calcareous deposits are organic in origin. in 1685. Cretaceous chalk is common across much of central Alabama. Because the positions of continents in the Miocene world were similar to where they lie today, it is easiest to describe the plate movements and resulting changes in the paleoclimate by discussing individual continents. The expansion of grasslands is correlated to a drying of continental interiors as the global climate first warmed and then cooled. Although I ended up finding a lot of tiny shells and shell fragments, they require a microscope to see and the fine details have made identification challenging. Carcharias magna
