[more ▼] The definition of the term cryptospore is amended to include only spores thought to be produced by embryophytes and to exclude all enigmatic palynomorphs. Cryptospores are included here in the miospore group.The oldest published assemblage of typical cryptospores is Llanvirn in age. The evolution of cryptospore assemblages is very slow from the Llanvirn to the early Llandovery. The Telychian and Sheinwoodian stages are periods of drastic impoverishment in cryptospore biodiversity, followed by an important modification in miospore assemblages. This step in the evolution of the vegetation is correlated with the rapid transgression of seas on the continent during the early Llandovery. On the other hand, the Hirnantian glaciation does not affect diversity of the miospore assemblages.

[more ▼] GeoArabia Special Publication 1 <br /> <br />Knowledge of the Palaeozoic biostratigraphy of the Arabian Peninsula, situated close to the northern margin of Gondwana, was poorly known until a joint special project was held by the Saudi Arabian Oil Company (Saudi Aramco) and the Commission Internationale de Microflore du Paléozoïque (CIMP) in 1990. Prior to that only a small number of investigations had been published. Few efforts had been made to exploit the strati-graphic potentials of the many undescribed indigenous microfossils. The joint Saudi Aramco-CIMP project was designed to reverse that situation. Comprehensive studies were carried out on a range of microfossil groups throughout the Palaeozoic and results were published in 1995. <br /> <br />The 13 papers presented in this GeoArabia Special Publication update those initial findings. They clearly indicate the potential for these palynomorph assemblages to not only to provide a method for well-to-well correlations within Saudi Arabia, but also for establishing the palaeo-biogeographical relationships of the Arabian Plate relative to adjacent landmasses. The conclusions that are proposed here can now be compared with datasets throughout North Africa and with the central and southern parts of South America. <br /> <br />Editors: Sa’id Al-Hajri and Bernard Owens <br />231 pages <br />40 plates/62 illustrations [less ▲] Detailed reference viewed: 21 (6 ULg)Preliminary survey of the palynological content of the Lower Devonian in the Oesling, LuxembourgSteemans, Philippe ; Debbaut, Vincent ; in Bulletin de la Société des Naturalistes Luxembourgeois (2000), 100 Detailed reference viewed: 11 (6 ULg)Annotations to the Devonian Correlation Table, B50di00: Miospore Palynology, Western EuropeSteemans, Philippe in Senckenbergiana lethaea (2000), 80(2), 759-760 Detailed reference viewed: 11 (0 ULg)Plants associated with Tentaculites in a new Early Devonian locality from Morocco.Gerrienne, Philippe ; Fairon-Demaret, Muriel ; et alin Abhandlungen der Geologischen Bundesanstalt (1999), 54 Detailed reference viewed: 17 (3 ULg)Spores and cryptospores from Llandovery layers in Saudi Arabia and their implications for the biostratigraphy at the Ordovician/Silurian boundarySteemans, Philippe ; ; Conference (1999) Detailed reference viewed: 6 (0 ULg) |
