Plant fossils, including incredibly well preserved, and delicate leaves, are a record of the environment, and help to demonstrate the different climatic changes the Earth underwent over many millions of years.

Most angiosperm plants are still unidentified, due to the huge diversity of species.
However, they are a unique insight into the prehistory of the world we live upon.
