Pinites

About

Pitus, also known as Pitys, is an extinct genus of early "pteridosperm" seed plant. A morphogenus representing wood, they are primarily known from remains found in Euramerica during the Early Carboniferous (Mississippian), including Newfoundland and Scotland. They are particularly well known from fossils found in southern Scotland of Viséan age when the area had a tropical climate. Their trunks reached at least 20 metres (66 ft) in height and 1 metre wide at the base, and were the tallest trees at the time. They are associated with rachis of Lyginorachis, and the leaves of Sphenopteris. They are considered to be part of the "hydrasperman" group of seed ferns. A distant relationship with modern cycads has been proposed. Attribution of remains from Australia to the genus has been questioned.
