Fossil Plants

"Plant" refers to familiar land plants, and also to aquatic plants, mosses, liverworts and algae plants. Although not technically plants, fungi and bacteria are often included. Palaeobotany is the study of ancient plant life using fossil evidence. Plant fossils are found coast-to-coast in Canada, from 45-million-year-old mosses in British Columbia to fossil forests on Axel Heiberg and Ellesmere islands in the Canadian Arctic.
