A. Ivanov participated in several international conferences and continues collaborative projects with Russian, French, and British researchers, particularly on placoderm and chondrichthyan fossils.
V. Lukin participated in northern field work (see above) and in several conferences and workshops, continuing his studies of Paleozoic corals and their stratigraphic distributions.
S. Melnikov participated in field work, workshops, and conferences, presenting results of his research on Early Silurian episodes at the Jurmala meeting of IGCP 406.
T. Modzalevskaya focused on Ordovician-Silurian brachiopods of the Taimyr Penninsula, reporting preliminary results at the meeting in Jurmala, and publishing on Upper Silurian brachiopods from Timan-Pechora in Acta Geologica Polonia. A revision of Pentamerus samojedicusis in press in Proc. Estonian Acad. Sci. O Telnova continued research on palynological correlations in Timan, presenting results at several meetings including the IGCP 406 meeting in Jurmala.
Yu. Tesakov presented a synthesis of Silurian zonation of the Siberian Platform and Taimyr at the Jurmala meeting.
V. Tsyganko took part in the Interdepartmental Stratigraphic Committee (Devonian commission) meeting in the Northern Caucausus in Essentuki), gave oral reports at several meetings, and published a number of proceedings papers and articles.
A. Yudina studied Upper Devonian sections on the Syv''yu River, Subpolar Urals. Palaeontological (goniatites, ostracodes, brachiopods, trilobites, conodonts, spores), sedimentological, and geochemical samples were collected. For the first time, the Givetian-Frasnian and Frasnian-Famennian boundary intervals were disclosed by trenches, and measured and sampled in detail. In 1999, A. Yudina defended successfully her Ph.D. thesis "Biostratigraphy and Upper Devonian conodonts of the ChernyshevRidge and Subpolar Urals".
A. Zhuravlev participated in the Jurmala meeting where he presented results of Devonian - Carboniferous conodont studies in the North Urals area, and implications for faunal crises at the end of the Devonian and in the Late Tournaisian.
Sweden:
Swedish participants H. Blom and J. Peel made progress in the following areas: 1) microremains of vertebrates from the upper part of the Franklinian Basin, North Greenland (H.Blom, J. Peel). 2) significance of the Devonian thelodont Amaltheolepis, based on material from the Circum-Arctic region (Blom). 3) taxonomic, biostratigraphic, and palaeogeographic significance of thelodonts in Spitsbergen (Blom). 4) birkeniid anaspids from the Circum- Arctic, Baltoscandia and Britain (Blom). 5) Palaeozoic stratigraphy of North Greenland (Peel). Blom made study visits to Paris, New York, and Tallinn, and participated in meetings/workshops in Uppsala and Jurmala, publishing several articles in international journals. He plans completion of his PhD thesis in the coming year. U. Borgen completed a major monograph on osteolepiforms from East Greenland.
Ukraine:
T. Nemirovskaya continues her studies of Carboniferous conodonts and biostratigraphy. United Kingdom:
S. Young, U.K. correspondent, reports that IGCP-406-related projects in UK involve taxonomic, biostratigraphic, sedimentological, palaeoecological, and palaeobiogeographical studies, as well as interpretations of sea-level fluctuations and reports of vertebrates, conodonts, palynomorphs, and ostracodes from early Palaeozoic localities in the Northern Hemisphere. Much of the work involves participation with scientific colleagues abroad. The collective importance of these individual and collaborative studies is much greater than just the sum of the individual work. UK project participants participated very actively in national and international meetings in 1999. Some 15 project participants from 11 countries attended the Palaeontological Associationmeetings at University of Portsmouth, and 13 presentations were authored by UK members of IGCP 406. IGCP 406 participant P. Ahlberg organized a Joint Meeting of the Systematics Association/Natural History Museum in April on the subject of Major Events in Early Vertebrate Evolution: Palaeontology , Phylogeny and Development. Of the 31 presentations, nine were by IGCP 406 participants. A symposium volume will include research papers by several project participants. At the meeting New Perspectives on the Old Red Sandstoneheld at Cambridge, several IGCP 406 participants attended and made presentations. At the International Symposium of Vertebrate Palaeontology and Comparative Anatomy held in Edinburgh at least five IGCP 406 members were active participants, and two project members (N. Trewin, R. Davidson) led the field excursion to Tillywandland Quarry. Finally, attendance and participation by UK members played a significant role at the IGCP 406 Annual Meeting in Jurmala, Latvia.
