Netherlands:
J. Vergoossen has made progress in two areas: 1) He has worked on erratic material from the Netherlands which he has related directly to drill cores by using particular acanthodians. Some 360 metres below the surface are scales similar to some from erratics from Lithuania. He intends to submit a paper in November. 2) Material from Sacania is similar to some of the material he has studied elsewhere.

F. Steeman (University of Amsterdam) has completed a study on "Arctaspis", from the Lower Devonian Wood Bay Formation of Spitsbergen, under the supervision of D. Goujet (France).

Poland:
M. Ginter visited colleagues in other European countries during 1998 (including France and England) collecting information. He also organized the Warsaw annual meeting of IGCP 406, and edited the conference volume (Ginter and Wilson 1998).

Russia:
A. Antoshkina, T. Beznosova, I. Evdokimova, A. Ivanov, T. Nemyrovska, N. Belyaeva, O. Afanassieva and husband, R. Matukhin, S. Melnikov, and T. Modzalevskaya, and M. Shishkin attended the Warsaw Meeting and made presentations. In addition to these, A. Abushik, Y. Gubin, A. Kanygin, A. Kuzmin, A. Orlov, D. Sobolev, V. Tsyganko, Y. Vevel, and A. Zhuravlev authored or co-authored reports for the meeting.

A. Abushik has completed a manuscript for a monograph "Lower Devonian ostracodes of Timan-Pechora Province" (together with L. Shamsutdinova), and of taxonomy, biostratigraphy and palaeoecology of Silurian and Early Devonian ostracodes from Severnaya Zemlya (papers on the subject are submitted). In the next year she will concentrate on Silurian and Early Devonian ostracodes from Novaya Zemlya and Kotel'ny Island.

O. Afanassieva continues to work with osteostracans primarily from the Severnaya Zemlya Archipelago. She submitted a manuscript (in co-authorship with V. Karatajute-Talimaa) on the distribution of the osteostracans for the monograph on Severnaya Zemlya (co-editors V. Menner and R. Matukhin). Now she is working on the
chapter "Osteostraci" for the handbook "Fossil vertebrates of Russia and adjacent countries". At the Warsaw meeting she reported the results of her studies of the thin exoskeleton of non-tremataspid osteostracans from Severnaya Zemlya (Afanassieva 1998 abstract, Afanassieva in press). Now she and T. Märss continue to study the remains of osteostracans from the Silurian and prepare a paper.

A. Antoshkina is preparing a paper on specific Palaeozoic reef associations of the Ural Mountains, Russia, and presented a paper on the subject in Warsaw (Antoshkina 1998 abstract). She also carried out field work in July, 1998, in the Northern and Middle Urals together with C. M.Soja (Colgate University, NY, USA) and B. White (Smith College, MA, USA) to study Upper Silurian reefs with sponge-microbial associations in accordance with a joint project (Northern Ural-Southeastern Alaska) with C. Soja (1996-1999). Publications on this subject are being prepared. She also plans to finish a post-doctoral manuscript about the platform margin reef formation in the Palaeozoic of the Pechora Urals the during first half of next year and to prepare materials for the field-guide to ICGP-406 Meeting in the Subpolar Urals scheduled for Syktyvkar in 2000.

N. Belyaeva is studying the sedimentology the Late Devonian - Early Carboniferous reef complex of the Timan Pechora and Volga Urals regions, and is preparing a post-doctoral manuscript on the subject. She has collected fish fossils, which are in St. Petersburg with A. Ivanov, this past field seasonin South Timan, Lyaiol' River, from fossil reefs. Belyaeva's manuscript based on the previous summer's(1997) field work is published. She also has an article published in the journal of her institution about the different kinds of fish fossils from the Frasnian/Fammenian which she has found (placoderms, Bothriolepis, etc.). Field work in 1999 is planned on the South Timan. She invites IGCP 406 participants to Syktyvkar to see these fishes.

T. Beznosova is preparing material on the Silurian sections for the field-guide in the Subpolar Urals in connection with the IGCP-406 Meeting in 2000. In 1999, field work will be on the Kozhim River in the Ordovician/Silurian boundary together with P. Mannik and S.V.Melnikov. Beznosova is also studying samples of the Ordovician/Silurian boundary in the Chernyshev swell, and materials on the Llandovery/Wenlockian boundary for a joint article with A. Antoshkina, S.Melnikov and P. Mannik.

S. Cherkesova continues to study Devonian rhynchonellids from Central Taimyr.

I. Evdokimovagave a talk in Warsaw about different Late Silurian - Early Devonian ostracode associations from the Eurasian Arctic. In the next year she will start to study Early Devonian ostracodes from the Kotel`nyi Island (Russia) and from the Northwest Territories, Canada. The Canadian samples, from IGCP 406-related field work at Anderson River, have been provided to her by H.-P. Schultze and S. Cumbaa.

A. Ivanov is working on the chapter "Placodermi" (all groups except antiarchs) in cooperation with Ervins Luk[!]eviãs (antiarchs) for the handbook "Fossil vertebrates of Russia and adjacent countries". Also, he is
