Summary
DescriptionProtolepidodendron (fossil plant) (Devonian; New York State, USA) (46348932661).jpg |
Protolepidodendron sp. - fossil plant from the Devonian of New York State, USA. (public display, Field Museum of Natural History, Chicago, Illinois, USA) Lycopods are one of the best known plant groups in the fossil record. They occur as relatively small, herbaceous forms and as large, arborescent forms (= scale trees, up to ~40 meters tall). The herbaceous lycopods first appear in the Devonian. During the Carboniferous, arborescent lycopods were the dominant terrestrial plants on Earth. The protolepidodendraleans are an extinct group of herbaceous lycopods known only from the Devonian and Mississippian. Their leaves ("microphylls") had bifurcate tips, unlike other lycopods. Well known protolepidodendraleans include Protolepidodendron itself (seen here) and Leclercquia. Classification: Plantae, Lycophyta, Protolepidodendrales Stratigraphy: unrecorded/undisclosed Devonian-aged unit Locality: unrecorded/undisclosed site in New York State, USA See info. at: <a href="http://www.ucmp.berkeley.edu/plants/lycophyta/protolepido.html" rel="noreferrer nofollow">www.ucmp.berkeley.edu/plants/lycophyta/protolepido.html</a> |
