Plane trees of London

Photographs of fossils

Index page

The genus Platanus is believed to be more than 100 million years old, and Platanaceae is one of the oldest known angiosperm families. Many fossilised specimens of plane leaves and fruit have been discovered in the northern hemisphere. These have been given a variety of specific names.

Fossil wood of plane trees have been discovered in places in Britain, so although the trees are 'exotics' now, it is because of their local extinction during previous ice ages. This article discusses plane fossils over 30 million years old found in various places in England. More recent fossils have been discovered in southern Europe.

The image below is of an unknown North American species.
