Plants

Plant images: all Psilophyton sp.

The earliest vascular plants can be found in rocks from the Middle Silurian.

The first plants were very small but in rocks in Australia from the end of the Silurian plants were found exceeding 30 cm in length.

In the early Devonian plants started to radiate and four different groups of plants can be distinguished: the Lycopods, the Rhyniophytes, the Trimerophythes and the Zosterophyllophytes. From the famous silicified material from the Rhynie Chert, a lower Devonian sinter deposit with exceptionally preserved plants and animals much has been learned about early plant life.
