Silurian Plant Fossils

The earliest land plants were found in Upper Silurian rocks. These are small, very simple plants consisting of naked axes, terminally bearing sporangia. In even older rocks isolated pieces of cuticle, tracheid-like structures and (crypto)spores can be found. These are, however, often still difficult to interpret.
