Cross section of a twig from a woody flowering plant that lived during the Eocene epoch, approximately 40 million years ago. The specimen is anatomically preserved by silica mineralization in rocks known as the Clarno Chert. All tissues are preserved, from the central pith to the outer bark. The plant was part of a subtropical community inhabiting marshlands in what is now central Oregon.
