Ferns are plants with true leaves, but without seeds.
Timescale: Ferns appeared about 360 million years ago. They are, of course, still with us.
This fern is Pecopteris from the Carboniferous age. It is from Braidwood, Illinois. Size: 40mm
These ferns are Alethopteris serli, from Radstock, Somerset, from Big Bright's seam coal measures, Upper Carboniferous.
Horsetails are related to ferns. There are still horsetails today (see left, found by an English road, and right, in Cambridge Botanic Gardens).
Modern horsetails are quite small, but the ancient horsetails grew very large. Below is a horsetail or Equisetum. It is from the Wadhurst clay, Freshfield Lane Quarry, Sussex. It is from the Cretaceous period.
Fossil size: 60mm
I'm not sure what these last two are!
