Plant Fossils

Plant fossils are less common than animal fossils. Leaves and other plant parts break down quickly under normal conditions. They can be preserved if they are quickly buried in the sediment of a lake or pond. We have plant fossils from various regions. The Metasequoia are from the muddy creek formation, and are about 30 million years old. The Green River formation has a variety of leaf fossils about 48 mya. The fern fossils come from Pennsylvania and are from the Pennsylvanian Epoch of the Carboniferous Period. They are about 300 million years old.
