Wang Nianzhong, a microvertebrate researcher, was elected as a new corresponding member of Subcommission on Silurian Stratigraphy at its 1998 meeting in Madrid, and continues his studies of thelodonts and other fishes from the Devonian of northern China and elsewhere (Wang 1997, Wang et al. In press).
O. Hints has finished a revision of the Ordovician and Silurian Ramphoprionid polychaetes from Severnaya Zemlya (results of this work are published). He plans to begin to study collections of scolecodonts from Siberia. E. Mark-Kurik presented in Warszaw two papers (Kurik 1998, Carr and Kurik 1998) dealing with placoderms (on Devonian assemblages of Severnaya Zemlya and on taxonomy and distribution of arthrodires). Two papers were also submitted for publication and a poster presented in Warsaw (Kurik submitted, Kurik et al. submitted and poster), one on correlation of units based on Devonian fishes of the Baltic states and the other on miospore assemblages from the Devonian of Estonia. Peep Männik represented IGCP 406 at ECOS VII in Italy and attended IGCP 406 in Warsaw. In both meetings he gave presentations about biostratigraphy, palaeogeographical distribution and provinciality of Telychian conodonts. He co-authored a paper (Märss et al. 1998) and an abstract (Märss et al. 1998) on vertebrate biostratigraphy in the Canadian Arctic islands. He continues to work with conodonts from Severnaya Zemlya and Novosibirsk archipelagos, and has started to process samples from northern Siberia. A study of carbon isotopes from Severnaya Zemlya in cooperation with T. Martma is in progress. Tiiu Märss submitted three manuscripts (two of them in co-authorship with V. Karatajute-Talimaa) for the Severnaya Zemlya monograph: one on Ordovician - Lower Silurian thelodonts, another on Upper Silurian thelodonts, and a third on Silurian - Devonian anaspids; one paper with O. Afanassieva on osteostracans is in preparation. A paper on thelodonts from Boothia Peninsula is also submitted. Work with M. Wilson, Edmonton, on taxonomy of thelodonts from the Canadian Arctic Archipelago has begun. T. Märss represented IGCP 406 at the Silurian Subcommission Meeting in Madrid (see Meetings and Märss et al. 1998 abstract), and published a paper (Märss et al. 1998) on Silurian/Devonian vertebrate biostratigraphy of Baillie-Hamilton and Cornwallis islands. She also published her major work on Silurian thelodonts from Scotland (Marss and Ritchie 1998) and a paper with many other authors on scolecodonts from Novaya Zemlya.
A. Blieck has assumed direction of UPRESA 8014. His studies of Spitsbergen and Severnaya Zemlya vertebrates should be finished in 1999. A brief paper on placoderms from Luxemburg (Blieck et al. 1998) was published, along with several other abstracts and/or reports on microvertebrates (see publications list). M. Ginter of Poland met with C. Derycke and A. Blieck at Villeneuve d'Asq to discuss Devonian-Carboniferous chondrichthyans. A. Blieck is also completing his report for IGCP project 328 Palaeozoic Micro-vertebrates, to be published by Cour. Forsch. Senckenberg, as well as acting as editor for that volume. C. Derycke-Khatir presented a paper in Warsaw on mid-Palaeozoic vertebrates from Mauritania. She now has a university position at Lille. P.-Y. Gagnier continues to work on material collected on Prince of Wales Island in the Canadian Arctic in 1995, and collaborated with Märss et al. (1998) on study of Silurian/Devonian vertebrates collected in 1994. He presented a paper (Gagnier et al. 1998 abstract) and has submitted a manuscript on a new acanthodian from the Mackenzie Mountains of Canada. He hopes to organise a field trip to the Arctic in the year 2000 or soon after. D. Goujet has concentrated on acid preparation and sorting of the material collected on Prince-of-Wales Island in 1995. A wealth of macro-remains (placoderms and heterostracans) prepared with the transfer method, as well as micro remains have been obtained from the residue together with silicified invertebrates (brachiopods, trilobites, coralos, ostracods, conodonts). The new material has provided evidence of several taxa of Acanthothoraci in the "Romundina" locality, with a report presented at the Warsaw meeting (Goujet 1998). Other Canadian Arctic studies were published in collaboration with T. Märss et al. (1998, 1998 abstract). A |
