Phylogenetic relationships of conifers inferred from partial 28S rRNA gene sequences.
Cl cladistic analyses using a new data set obtained from 28S rRNA gene sequences strongly support the monophyly of conifers including Taxaceae and suggest that the common ancestor of these families, both having the greatest diversity in the Southern Hemisphere, inhabited Gondwanaland.
The Permian-Triassic Khuff Formation of central Saudi Arabia
The Permian-Triassic Khuff Formation crops out in central Saudi Arabia along a N-S belt, some 1,200 km in length. It is 171.4 m (562.2 ft) thick in the type section and divided into five members;
The Permian Pangea. Phytogeographic implications of new paleontological discoveries in Oman (Arabian Peninsula)
This paper focuses on new paleontological discoveries that have come to light while working on a Permian paleobotanical transect, from Oman to Central Morocco. In the Huqf area, the continental plant
The Permian-Triassic boundary and Early Triassic sedimentation in Western European basins: an overview
At the scale of the peri-Tethyan basins of western Europe, the “Buntsandstein” continental lithostratigraphic units are frequently attributed to the “Permian-Triassic” because, in most cases, the
