Plantae: Fossil Record

Chart of First Appearances of Major Groups

The above chart shows the oldest undoubted fossil occurences of each of the major groups of plants. Note that a major radiation occurred in the Devonian, at which time the earliest vascular plants and seed plants appeared.

The above image is mapped! We have additional information on the geological time periods along the top of the image. Also, each of the taxonomic groups in pink boxes can be clicked upon to take you to its exhibit in our museum.
