Expanding terrestrial habitats and food webs are coincident with the origin of terrestrial vertebrates and by the end of the devonian the first terrestrial ecosystems were well established. Despite this marked radiation in biodiversity, the end of the devonian is marred by major extinctions of which the causes and effects thereof are poorly known.

The early devonian posongchong flora of yunnan is a monographic summary of current knowledge of the early devonian posongchong flora from yunnan, southwestem china, which is emerging as one of the most important sources of information on early vascular plants. The many species recovered from the posongchong formation, including some endemic plants with unusual combinations of fertile and vegetative organs, are described in detail, and an updated classification system is presented.
Plant systematic diversity one main objective of my work is to provide a better understanding of the composition and dynamics of devonian- jurassic floras, including (a) the time of apparition and diversification of some key groups and (b) how/if plant diversity was impacted by major environmental changes.
The devonian period is sometimes called the “age of fishes” because of the diverse, abundant, and, in some cases, bizarre types of these creatures that swam devonian seas. Forests and the coiled shell-bearing marine organisms known as ammonites first appeared early in the devonian. Late in the period the first four-legged amphibians appeared, indicating the colonization of land by vertebrates.
The early land plant group zosterophyllopsida has a wide distribution in the global silurian to devonian floras and the morphological study of this group is fundamentally significant to plant evolution. Demersatheca contigua is an endemic zosterophyllopsid of the early devonian flora in south china.
Reproductive structures of frasnian (early late devonian) age from wuhan, hubei province, south china provide evidence for the early emergence of monomegaspory and integumentation in plants of non-progymnosperm affinity.
Look at late devonian plant life from a nonequatorial paleolatitude. The vast majority of current information concerning late devonian plants has come from regions of north america and europe that were probably near-equatorial in setting during this time period. Now, knowl-edge of the probably subtropic (? 10?-30? paleolatitude).

Sublepidodendron is a common megafossil plant in the late devonian of china, but historically the generic delimitation based on leaf bases masked its true systematic position. Songziense from the late devonian hsiehchingssu formation, hubei, china, provides new insights into its internal anatomy and reproductive.

The late silurian to early devonian period represents one of the most critical times in earth history, when vascular plants invaded the land and formed the first complex terrestrial ecosystems.
Protocephalopteris and rhacophyton) is a group of middle to late devonian plants placed by some authorities within the zygopteridales. They share several anatomical details of vascular tissues with the zygopterids, but they differ significantly in the structure of their fertile branches.
