It has been a very busy year for Palaeozoic spore and pollen workers. This is witnessed by the large numbers of research presentations that have been given at the many conferences around the world. More than 80 titles of research papers and abstracts have been collected in the Newsletter. Many thanks to those of you who sent in this information. Please continue to do so. The Subcommission Officers are hoping that next year will see a continuation of this high level of activity and that many of you will be able to present research findings at the first meeting of the Subcommission. This is being arranged by the Subcommission Chairman at University College Cork. Ken is currently working on the programme and has planned interesting field visits for delegates. Details are given elsewhere in the Newsletter. At the time of publication we have already received several offers of presentations, and so we anticipate that this will be a well attended and lively meeting.

2. Calls for Assistance

The following are areas that should be covered in the Newsletter. Some of these are now being covered, although probably notcomprehensively, by the Newsletter. Similar things can already be seen in the Newsletters of the Acritarch and Chitinozoan Subcommissions. 1. List of recent publications and presentation abstracts. Probably the most important role for the Newsleter is to keep the membership informed of current research. In the present climate of library cutbacks, titles from provincial journals and from conferences are in particular need of advertisement. In this area there will be an important benefit to all members. The Newsletter aims to produce an up-to-date listing of all publications and presentations titles for each year. Over time these list will be added to the Subcommission webpages to provide a downloadable archive of Palaeozoic spore/pollen references. 2. Recent thesis abstracts A research thesis or dissertation rarely sees the light of day outside of its own Alma mater. As with research papers, the palynological community would benefit from wider knowledge of the existence of many of these. An aim of the Newsletter is to produce an up-to-date listing of all doctoral research titles up to the present and (where candidates allow) reproduction of abstracts. Over time this list will be added to the Subcommission webpages to add to the downloadable archive of Palaeozoic spore/pollen references. 3. Recent taxonomic developments Again, it is intended that the Newsletter should act as a means of advertising taxonomic devleopments such as the erection, recombination or emendation Palaeozoic spore/pollen taxa. 4. Subcommission membership For whatever obscure historical reasons, C.I.M.P. has oftern been viewed as a european organisation and has had gaps in its membership which can largely be recognised as geographical. C.I.M.P. and its Subcommissions should be international and should include all Palaeozoic palynologists who wish to be members. In order to achieve this I would urge the current Spore-pollen Subcommission membership to encourage their colleagues to become affilliated. The work of the Subcommission will only be really effective if it has comprehensive input from the world of Palaeozoic spore/pollen studies.

In all of the above cases, the Newsletter can only carry comprehensive and current information if the membership keep the Newsletter compilers informed of developments. So please make a point of letting us know of anything that you produce that will be of relevance to other Palaeozoic spore and pollen workers around the world.

Have you paid your C.I.M.P. subscriptions?

Rates are exceedingly low and are vital for the continued operation of the organisation. Subscriptions pay for reproduction and postage of all Commission and Subcommission Newsletters. See current C.I.M.P. Newsleter for details Please act now! 3. Activities of Working Groups

In their role as facilitators to the Subcommission the Chairman and Secretary are keen to see the establishment of new and successful Working Groups. These should vary in scope (taxonomic, stratigraphic, palaeoenviromnmental or palaeoecological..etc) and identify worthwhile areas of specific study. If you are interested in setting up your own Working Group under the aegis of the Spores and Pollen Subcommission, please contact the Chairman or Secretary. While there are no rigorous criteria to be met before establishing a C.I.M.P. Working Group such a group should have clearly defined and achievable research aims and should result in publications which benefit all of its contributors. If in doubt please feel free to contact any of the coordinators of existing Working Groups for advice.

C.I.M.P. Working Group on Dinantian-Namurian palynostratigraphy

During the meeting on Carboniferous Stratigraphy (SCS) held at the 13th International Congress of Carboniferous - Permian (ICCP) in Krakow in 1995, it was proposed to establish a multidisciplinary working group on the definition of the Viséan - Namurian boundary and its global equivalents. One of the first steps was to set up a palynological sub-group to compile and contribute to the palynological component to the Project. John Utting (GCS Canada) and Zhu Haucheng (Nanjing) agreed to work with Bernard Owens (BGS UK) to establish this new C.I.M.P. working group. If you have any interest in the Viséan - Serpukhovian or Late Mississippian palynology, why not join the working group? Perhaps you could supply data or material. All offers of help are welcome. The first objective is to establish a global network for co-operation on this problem to make real progress before the next ICCP in 1999. Why not join now and indicate how you can contribute, what you are working on and what material you are able to offer for study. Contact: Bernard Owens (e-mail: [email protected]) C.I.M.P. Working Group on Gondwanan Permo-Carboniferous palynostratigraphy

The Working Group was founded in 1999 to investigate Gondwana-wide palynostratigraphic correlation in an interval where other biostratigraphic media are scarce. The Group includes representatives of oil companies active in the Arabian Peninsula and Brasil, and academics from India, Argentina, Brasil, Germany, UK and Uruguay. A formal list of objectives has yet been agreed but may include: 1. Compilation of an 'electronic' atlas of key palynomorphs from the Arabian and South American basins; 2. Exchange of literature, slides and type material. Members of the Working Group have met informally, though never all together. At the ICCP in Calgary in 1999, Mike Stephenson (UK) met Rosaline Weiss (Germany) and Rodolpho Dino (Brasil). Mike met Paulo Alvez de Souza (Brasil) and members of the CIMP-Saudi Aramco Palynostratigraphy project at the IGC in Rio de Janerio. At the invitation of Rodolpho Dino he visited the Petrobras research centre in Rio to discuss similarities between assemblages in the Parnaíba and Arabian basins. The Working Group has produced an atlas of key Arabian palynomorphs, compiled by Mike Stephenson. A similar atlas for South American basins is planned. A short report of collaboration was also circulated amongst the Group members. It details a number of key palynomorph species, some unpublished, which appear to be common to the widely separated Al Khlata and Parnaíba basins, indicating the possibility for real progress in pan- Gondwanan correlation. Mike Stephenson is currently seeking funding to investigate a possible deglaciation related flooding event in the Gharif Formation of Oman. The dispersed nature of the Group membership has made meeting difficult, but some real progress has been made showing that collaboration can be achieved by electronic means. It is hoped that members of the group will continue to work together.

T Working Group is intended to deal with problems in late Namurian and early Westphalian palynostratigraphy in Europe, North Amewrica and South America. The Group will be please to hear from the C.I.M.P. members who would like to join them and who can contribute material, slides, photographs and ideas. If you are interesested in the Working Group, please contact: Duncan McLean (e-mail: [email protected]) Centre for Palynology, Dainton Building, University of Sheffield, Brook Hill, Sheffield, S3 7HF, UK.

C.I.M.P. Working Group on cryptospore systematics

Recent rapid developments in the study of pre-Devonian terrestrial palynomorphs indicates an opportunity for workers to co-operate in the field of cryptospore systematics. It is intended to establish a Working Group within the C.I.M.P. to encourage discussion and exchange of materials. This area of study is still small enough to allow for a meaningful and workable classification and inventory of taxa be established. In order to discuss the format and aims and objectives for such a group Dr. Charles Wellman has agreed to act as an initial coordinator. If you are interested in establishing and developing this Working Group please contact Charles Wellman (e-mail [email protected]) Centre for Palynology, Dainton Building, University of Sheffield, Brook Hill, Sheffield, S3 7HF, UK.

Book Review

Stratigraphic Palynology of the Palaeozoic of Saudi Arabia edited by Said Al-Hajri and Bernard Owens (2000). Special GeoArabia Publication 1, Gulf PetroLink, Elsevier Science ISBN 99901-04-01-8, 231pp, 40pl, 62 illustrations.

Despite the significant hydrocarbon interest in the Arabian Peninsula there are relatively few publications concerning the region’s Palaeozoic biostratigraphy. However, ongoing collaboration between Saudi Aramco and CIMP has allowed the production of a volume that supplements initial findings reported in 1995. It contains 13 papers concerned with stratigraphic and taxonomic relationships of palynomorphs from Cambrian to Permian subsurface sequences. 5 genera and 23 species are newly described. The books high standards of layout, presentation and production are immediately obvious with clear colour diagrams, range charts and plates. The introductory paper by Al- Hajri and Owens provides a synthesis of all of the studies and is a useful reference base that allows the reader to understand the subsequent papers in geographical and geological context. Two correlation panels summarise the stratigraphical scope of the whole project. Molyneux describes acritarch, chitinozoan and cryptospore assemblages from the extensive “Ordovician” sandstone succession in central Saudi Arabia. He reinterprets the units as Early to Mid Cambrian to Early Silurian. Palynological range charts from 11 wells are provided and form the basis for correlation with sequences in northwest Saudi Arabia. Paris et al. describe Ordovician chitinozoan assemblages from the Qasim Formation of central Saudi Arabia. These are placed in a stratigraphical context and their palaeobiogeographical distributions considered. The paper demonstrates the use of Ordovician chitinozoans in local and regional correlation. Excellent SEM photomicrographs are presented. Le Hérissé reports the characteristics of acritarch assemblages from the early Silurian Qalibah Formation. He concentrates on the evolution of Llandovery acritarch biodiversity and biostratigraphy, and the local and regional correlation potential of the assemblages. He considers the significance of acritarch biology and palaeoecology for acritarch biostratigraphy. Al-Ruwali describes acritarch species from the Qalibah Formation and considers their biostratigraphy and palaeoenvironmental significance. Steemans et al. report on cryptospores and trilete spores from a borehole with independent chitinozoan and graptolite control in central Saudi Arabia. They propose a biozonation for the Ashgill-Llandovery boundary based on first appearences and relative abundances of spore taxa. Wellman et al. describe spore assemblages from the Rhuddanian-Homerian to ?earliest Gorstian Sarah and Qalibah Formations. Several cryptospore and trilete spore taxa are described. Three assemblages are recognized and correlated with existing Silurian spore biozones. Palynofacies are briefly described and compared to those from coeval sequences elsewhere. Loboziak records Eifelian to Frasnian miospores from northern Saudi Arabia. The miospores are typical of both Gondwanan and Euramerican provinces. An outline biozonation for western Gondwana based on the first appearance of significant miospore morphologies is proposed. Clayton et al report on Famennian to Namurian miospore assemblages from central and northern Saudi Arabia and the Arabian Gulf. Assemblages are correlated with biozones of Western Europe, North Africa and Brazil. The implications of the hiatus between the Devonian and Carboniferous is discussed. Owens et al. tackle problems encountered with Carboniferous litho- and biostratigraphy in the region. They describe mid Carboniferous miospore assemblages from eastern Saudi Arabia and discuss implications of the biostratigraphy and the gondwanan character of the assemblages. Comparisons with coeval assemblages from adjacent parts of northern Gondwana are made and the significance of reworked Famennian-Tournaisian material is discussed. Stephenson and Filatoff present a correlation of latest Carboniferous and Permian palynological assemblages from Oman and Saudi Arabia, and compare them to coeval assemblages from North Africa, South America and Australia. Similarities in the successions seen in Arabia, Australia and South America are used to support inter-regional correlations. In a second paper these authors describe Late Permian assemblages from the Khuff Formation of central Saudi Arabia. These are compared to ones from Russia, Iraq and Pakistan. Quantitative differences between the Arabian assemblages and those from Australia, India and Antarctica are considered to represent significant Late Permian phytogeographical differentiation of Gondwana. Evidence is given for the duration of the pre-Khuff unconformity. The final paper by Marshall provides information on palynofacies and orbital cyclicity from the Silurian Qalibah Formation. Facies cycles recognized in gamma-ray logs are used to identify Milankovitch periodicities that are used to estimate sedimentation rates and assess burial history. In all, the volume is neatly laid out, the papers are well written, well organized and arranged in a sensible order. It provides a sound basis from which to study the Palaeozoic palynology of Saudi Arabia and surrounding regions and will act as a useful database for a previously data-poor region. While reproduction is excellent, the cost is high ($300). The absence of individual reprints means that circulation of this excellent work may be limited. Instruct your librarian to buy a copy!

9. Requests for Reprints

1. It would be of great help if all palynologists who are working on Gondwana and Perigondwana would send me reprints of their papers immediately after publication. Relevant information will be included in the “Cologne Database of Palynomorphs” (a stratigraphical, geographical and taxonomic index). Cordial thanks to all those who did so in the past. Dr. Roseline Weiss, Universität zu Köln, Geologisches Institut, Zülpicher Str. 49a, D-50674 Köln. 2. Please help to keep the Subcommission Newsletter and website databases of current publications and abstracts up to date. Please e-mail me with any titles concerning Palaeozoic spores and pollen once published (not in press, please). I would also appreciate receiving reprints of these once available.
