Cordaites is a genus of extinct gymnosperms, related to or actually representing the earliest conifers. These trees grew up to 100 feet (30 m) tall and stood in dry areas as well as wetlands. These trees grew up to 100 feet (30 m) tall and stood in dry areas as well as wetlands.
The conifers are an ancient group, with a fossil record extending back about 300 million years to the Paleozoic in the late Carboniferous period; even many of the modern genera are recognizable from fossils 60–120 million years old.
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.
Podozamites is an extinct genus of fossil conifer leaves. In its broader sense, it has been used as a morphogenus ( form taxon ) to refer to any broad leaved multi-veined conifer leaves. Modern broad-leaved conifers with a similar form include Agathis in the family Araucariaceae and Nageia in Podocarpaceae , with some Podozamites sensu lato ...
Cheirolepidiaceae (also spelled Cheirolepidaceae) is an extinct family of conifers.They first appeared in the Triassic, and were a diverse and common group of conifers during most of the Mesozoic era, primarily at low latitudes, [1] where they often formed a dominant element of the vegetation. [2]

Araucarioxylon arizonicum (alternatively Agathoxylon arizonicum) is an extinct species of conifer that is the state fossil of Arizona. [1] The species is known from massive tree trunks that weather out of the Chinle Formation in desert badlands of northern Arizona and adjacent New Mexico, most notably in the 378.51 square kilometres (93,530 acres) Petrified Forest National Park.
