v. 22

This is the companion volume to the already-published "Palaeozoic Palaeobotany". The history of the changing environments and evolution of the plant groups is traced through the detailed descriptions of the c.52 sites, indicating the rise of conifers and cycads in the Mesozoic and, in Tertiary times, the angiosperms (flowering plants) which began to predominate at the expense of earlier plant types.
