Carboniferous is the period during which both terrestrial animal and land plant life was well established. [10] Stegocephalia (four-limbed vertebrates including true tetrapods ), whose forerunners ( tetrapodomorphs ) had evolved from lobe-finned fish during the preceding Devonian period, became pentadactylous during the Carboniferous.

Lepidodendron is an extinct genus of primitive lycopodian vascular plants belonging the order Lepidodendrales.It is well preserved and common in the fossil record. Like other Lepidodendrales, species of Lepidodendron grew as large-tree-like plants in wetland coal forest environments.
Pteridospermatophyta, also called "pteridosperms" or "seed ferns" are a polyphyletic [1] grouping of extinct seed-producing plants. The earliest fossil evidence for plants of this type are the lyginopterids of late Devonian age. [2] They flourished particularly during the Carboniferous and Permian periods.
Calamites is a genus of extinct arborescent (tree-like) horsetails to which the modern horsetails (genus Equisetum) are closely related. [1] Unlike their herbaceous modern cousins, these plants were medium-sized trees, growing to heights of 30–50 meters (100–160 feet). [2]
Etching depicting some of the most significant plants of the Carboniferous. Coal forests were the vast swathes of freshwater swamp and riparian forests that covered much of the lands on Earth's tropical regions during the late Carboniferous ( Pennsylvanian ) and Permian periods.
[2] [3] Lycophytes were some of the dominating plant species of the Carboniferous period, and included the tree-like Lepidodendrales, some of which grew over 40 metres (130 ft) in height, although extant lycophytes are relatively small plants. [4] The scientific names and the informal English names used for this group of plants are ambiguous.

Sphenophyllales is an extinct order of articulate land plants and a sister group to the present-day Equisetales . They are fossils dating from the Devonian to the Triassic. They were common during the Late Pennsylvanian to Early Permian, with most of the fossils coming from the Carboniferous period. [1] [2]
