This University of California Berkeley Museum of Paleontology site provides an interactive geologic timescale that illustrates the temporal distribution of several important plant groups. First appearances of major plant groups are plotted on a colorful timescale and each group is linked to references, text, images, and further information. Key Cretaceous plant groups featured include Anthocerotophyta, Anthophyta and Gnetales. The site might be a useful resource for constructing introductory level lectures concerned with paleobotany and paleoecology of the Cretaceous Period.
