The first permineralized Devonian plant fossil is reported here from the Middle or lowermost Upper Devonian of western Venezuela, and an iridopteridalean affinity for these plants is demonstrated, resembling Arachnoxylon kopfii Read in arrangement and number of xylem ribs although it is smaller in size.
EARLY EVOLUTION OF LAND PLANTS: Phylogeny, Physiology, and Ecology of the Primary Terrestrial Radiation

The Siluro-Devonian primary radiation of land biotas is the terrestrial equivalent of the much-debated Cambrian “explosion” of marine faunas, which ended with the formation of evolutionary and ecological frameworks analogous to those of modern ecosystems.
Giant cladoxylopsid trees resolve the enigma of the Earth’s earliest forest stumps at Gilboa

The evolution of trees of modern size growing together in forests fundamentally changed terrestrial ecosystems. The oldest trees are often thought to be of latest Devonian age (about 380–360 Myr old)…

A 1,200 m2 map showing numerous Eospermatopteris root systems in life position within a mixed-age stand of trees is described, describing the overall habit for these surprisingly large aneurophytaleans, the earliest fossil group having wood produced by a bifacial vascular cambium.
The Anatomy of Rotoxylon dawsonii comb. nov. (Cladoxylon dawsonii) from the Upper Devonian of New York State
New anatomical evidence indicates Rotoxylon is unusual, exhibiting diagnostic traits of both Cladoxylopsida and Iridopteridales, thus challenging current phylogenetic interpretation of both groups.

- 1 April 1978
All evidence currently available leads to the conclusion that this species should be placed in the Upper Devonian to Lower Mississippian Calamopityaceae, and represents a new member of the New Albany Shale flora.
