We sell fossil plants in our webshop. The first fossils that clearly resemble ‘plants’ are fossil green algae from the Cambrian. A period that lasted from 540 million to 485 million years ago. Algae, of course, do not resemble the plants that we know today. The real first land plants as we know them now come from the Silurian period that began around 420 million years ago. Prior to this period, the continents / land were dry stony places without life; just rocks. In our webshop we sell a wide variety of fossil plants and fossil ferns, including fossils from the famous Mazon Creek formation.
