Journal ArticleDOI
Palaeozoic tropical rainforests and their effect on global climates: is the past the key to the present?
TL;DR: Wetland forests, known as coal forests, extended over large areas of the palaeotropics during the Late Carboniferous and the Permian Periods as discussed by the authors.
Brief history of the gymnosperms: classification, biodiversity, phytogeography and ecology
TL;DR: A global synthesis of gymnosperm families, fossil and extant, provides a new and distinctive perspective on the macroevolutionary biodiversity trends within this group through their 375 million-year history.
Journal ArticleDOI
The relationship between Euramerican and Cathaysian tropical floras in the Late Palaeozoic: Palaeobiogeographical and palaeogeographical implications
TL;DR: In this paper, taxonomic and systematic investigations undertaken on the plant fossils from the Pennsylvanian Benxi Formation and the Early Permian Taiyuan Formation from China are presented.

TL;DR: In this article, it was shown that during the Silurian and Early Devonian time, many oceans became narrower so that only the less mobile animals and plants remained district, and each of these closures was reflected by migrations of non-marine plants and animals as well as by contemporary deformation.
