Cordaitales

Cordaitales are an extinct order of gymnosperms, known from the early Carboniferous to the late Permian. Many Cordaitales had elongated strap-like leaves, resembling some modern-day conifers of the Araucariaceae and Podocarpaceae. They had cone-like reproductive structures reminiscent of those of modern conifers. Some Cordaitales formed large trees that seem to have been particularly abundant on drier ground, in tropical environments. Also, some tall trees but also shrubby and mangrove-like species of Cordaitales seem to have grown in the Carboniferous coal swamps. Cordaitales were also abunda

Cordaites is a genus of extinct gymnosperms, related to or actually representing the earliest conifers. These trees grew up to tall and stood in dry areas as well as wetlands. Brackish water mussels and crustacea are found frequently between the roots of these trees. Cordaites fossils are most commonly found in rock sections from the Upper Carboniferous () of Europe and the Americas. thumb|left|Leaves of Cordaites lungatus A number of many types from this line are: Cordaites principalis Cordaites ludlowi (named after Ludlow, a coal area in England) Cordaites hislopii.

Cordaitaceae is an extinct family of conifers. It was named after Czech botanist and mycologist August Carl Joseph Corda.

Samaropsis is a form genus named by Goeppert in 1864. Later Sewart (1917) redefined the taxon to refer only to the seeds.
