Several IGCP participants were speakers at that symposium (e.g., Elliott, Wilson, Schultze, Goujet), and a number of other IGCP 406 members were attracted by the symposium to attend the meeting, where they presented research papers.
H.-P. Schultze continued to study the skeletal material of fishes from Anderson River, NWT, Canada. The age has been determined as Emsian by A. Abushik and I. Evdokimova, All-Russian Geological Institute, St. Petersburg, based on the occurrence of Moellerita, a large ostracode. Schultze and S. Cumbaa (Canada) have a paper in press on the primitive actinopterygian fish Dialipina.Schultze presented two talks (London and Jurmala) with associated abstracts, one on Dialipinaand the other on the primitive dipnoan (lungfish) Melanognathusfrom the same locality.
With M. Otto, Shultze studied Middle Devonian fishes from the south of Strathcona Fjord, Ellesmere Island, Arctic Canada. The material was collected by a German expedition in 1975 under the leadership of H.-P. Schultze. There will be two manuscripts, one on the whole fauna and stratigraphy (Otto, M., Schultze, H.-P. & Langenstrassen, F.: Middle Devonian vertebrates from Ellesmere Island, Canadian Arctic) and one on a new antiarch (Otto, M.: A new asterolepid antiarch from Arctic Canada).
Ireland:
M. Duncan continues writing her thesis on Lower Carboniferous (Tournaisian and Tournaisian/Visean) ichthyoliths from Ireland, including more than 90 plates illustrating the microvertebrate fauna. She also participated in the Jurmala meeting of IGCP 406.
Japan:
Once again M. Goto was active in IGCP 406-related research, publishing a number of papers and reports emaphasizing the evolution of bony tissues in vertebrates and the fossil record of chondrichthyans in Japan (see publications list).
Latvia:
Ervins
Luk[!]eviãswas the main organzer of the Jurmala meetings of IGCP 406 and Baltic Stratigraphical Conference; in connection with the meeting he edited (with G. Stinkulis and M. Wilson) the conference volume Ichthyolith IssuesSpecial Publication 5. He continues his studies of bothriolepidid antiarchs from the Severnaya Zemlya and Timan-Pechora regions.
I. Upeniece participated in the Jurmala meeting and is nearing completion of her doctoral thesis on Devonian fishes and associated fossil parasites from Lode Quarry, Latvia.
G. Stinkulis participated in the organization of the Jurmala meeting and the post-conference field excursion. Lithuania:
V. Karatajute-Talimaa made progress with her thelodont, heterostracan and chondrichthyan collections from Timan-Pechora region and with oldest acanthodian (S1) collection from Siberia, Tuva and Mongolia. J.Valiukevi
ãius 1999 also made progress with his acanthodian collection from the Timan-Pechora region. Many scale taxa have been identified and photographed. Their stratigraphic significance was also more clearly defined, but there is still so much to do. During 2000 this work will be continued.
R.Mertiniene has continued her work on chondrichthyan teeth and scales collection from the Upper Devonian - Lower Carboniferous of the Timan-Pechora region and the Main Devonian Field.
Jonas Seckus, a 4th year University student, began a study of actinopterygian scales and otoliths from the Middle- Upper Devonian of the Baltic.
Netherlands:
J. Vergoossen has studied Late Silurian fish microfossils from Ramsasa, Sweden, and has a paper in press in Geologie & Mijnbouw.
Poland:
Michal Ginter continued to study the taxonomic composition of late Famennian chondrichthyan assemblages in relation to palaeogeography and facies. Recently studied material includes chondrichthyans and conodonts from the expansa Zone of Soureillé d'Izarne (Montagne Noire, France). He represented IGCP 406 at the SDS Conference in Morocco, April-May 99, presenting a poster: Palaeozoic chondrichthyan microfossils as facies indicators. Plans for 2000 include a study of Late Devonian - Early Carboniferous chondrichthyan microfossils from the Rocky Mountains, North America.
