Tobleria bicuspis, a coniferophyte seed cone, is described from the Jambi Palaeoflora, Sumatra of Asselian (early Permian) age. A morphometric analysis based on cones, paired fertile units, and fertile and sterile scales, demonstrates their close rel

The Zonguldak – Amasra Coal Basin in north-western Turkey has Carboniferous terrestrial deposits ranging in age from Arnsbergian to late Asturian or possibly early Cantabrian. They yield macrofloras that allow detailed biostratigraphical correlatio

Although araucarioid wood is poor in diagnostic characters, well in excess of 200 Late Paleozoic species have been described. This study presents a largescale anatomical analysis of this wood type based on the fossil wood collections from the Early P

Shell beds pose questions of provenance, but determining the degree of pre-depositional transport of bioclasts can be speculative. Bioclastic beds deposited on a broad, shallow continental shelf may consist of a minimally transported accumulation. In

The gigantopterids are a pan-palaeotropical Late Palaeozoic (to Early Mesozoic) plant group with unknown affiliations. Two gigantopterid species, both sole representatives of their respective genera, are known from the Early Permian Mengkarang Format

Recent expeditions to the Early Permian formations of Jambi, Sumatra, have produced material of a new species of peltasperm affinity, Comia variformis nov. sp., with a remarkably broad morphological range that touches on several other Permian taxonom

For over 85 years, the stratigraphic determination of the Tabir Formation of Sumatra has been confused by a single fossil identification. Professor Fritz Frech recognized a specimen collected at the Batoe Kidjing locality by August Tobler to be an in

New material of the Early Permian alethopterid genus Macralethopteris is examined in detail. The material stems from different locations and statistical comparison of the morphological differences between collections suggests that the material is der
