vertebrates,
particularly acanthodians and placoderms. She met with S
Turner at the Natural History Museum, London, in July,
and attended the Warsaw meeting of IGCP 406 as well as
the 46th Symposium of Vertebrate Palaeontology and
Comparative Anatomy at Bournemouth in September, 1998. S.
Y. completed her chapter on surface micro-ornament of
scales of British acanthodians for the Special Report on
Palaeozoic Vertebrate Micro-remains of the U.
K.

R. Carr has been working with E. Kurik are on the
taxonomy of
Heterosteusand
Homosteus. They are also working on
freshwater/marine Scottish material, and also on the
Cleveland Shale, and updating descriptions of other
placoderms.
D. Elliott recently published a
paper on vertebrate biostratigraphy and another on a new
species of cyathaspid from the Northwest Territories of
Canada. He is currently Editor (Lower Vertebrates) for
the Journal of Vertebrate Paleontology, and is now
collaborating with R. Thorsteinsson on completion of a
monograph on Canadian Arctic heterostracans.
J. Repetski is working on
Ordovician conodont-bearing craters, some of them from
northern regions, with M. Lindstrom (Lindstrom and
Repetski 1998 abstract). A volume of Ordovician
circum-polar correlation charts is in press, and a
manuscript on the conodont genus
Clavohamulusfurnish,
which occurs in northern Alaska, is nearly ready for
submission.
G. Johnson and M. Williams both
attended the Warsaw meeting, presenting papers at the
workshop on Palaeozoic chondrichthyan fossils. Both also
attended the Society of Vertebrate Paleontology meeting
in Salt Lake City, U.S.A.
Societal
benefits
Benefits include greater
international cooperation, especially for this year the
successful large-scale contacts between Eastern European
and Western researchers of Circum-Arctic Palaeozoic
biostratigraphy and paleontology at the Warsaw meeting;
assistance for scientists including graduate students
from countries with limited financial resources;
dissemination of knowledge about geological sections
where multidisciplinary studies can be undertaken; and
discovery of and intensive study of exceptional
fossiliferous deposits (e.g. Devonian localities at
'MOTH' and Anderson River in the Northwest Territories of
Canada; Devonian tetrapod- bearing sites in East
Greenland) that might need future protection under
national or international laws.

Smaller
Meetings and Field Trips (funded by other
agencies):
Field Work in Silurian and Lower
Devonian of Northern Canada
Avalanche Lake and MOTH sections, N.W.T., Canada,
July 15 - August 7, 1998
Five researchers from 2
countries, led by Drs. M. Wilson and B. Chatterton,
Canada, with Dr. H.-P.
Schultze, Germany, M.Sc.
student B. Hunda and Ph.D. student G. Hanke, Canada. This
field work
resulted in collection of
geochemical and micropalaeontological samples from
sections across the
Ordovician/Silurian
boundary and across the Llandovery/Wenlock boundary in
the Avalanche Lake
sections, as well as
through the fossiliferous interval in the Lochkovian part
of the MOTH section.
Numerous macrofossils of
Silurian and Devonian vertebrates were also
collected.
Field Work in the Devonian of
Eastern Greenland
This field work led by Dr. J. Clack, U.K., resulted
in the collection of significant new remains of early
tetrapods, as well as documentation of sedimentological
context and associated flora and fauna.
