General Scientific Achievements
The major aim of this last year of IGCP 328 activities has been to
prepare
a Final Scientific Report (FSR) in the form of global correlation
charts
for each Palaeozoic System. This was clearly announced in our
original
plans. This FSR will be published as a Courier
Forschungs-Institut
Senckenberg volume (general editor P. Königshof,
Frankfurt-a/Main). The
volume is well advanced and will include the following
chapters:
Editors - Alain Blieck & Susan Turner
PALAEOZOIC MICROVERTEBRATE BIOCHRONOLOGY
AND GLOBAL MARINE/NON-MARINE CORRELATION

It is quite evident that most results come from the Devonian
System also
known as "The Age of Fishes". This is why 8 synthetic chapters are
devoted
to it. However, all other systems are concerned with
vertebrate
microremains from the Cambrian/Ordovician boundary up to the Late
Permian
(and beyond - the next phase of the research plan of the
International
Working Group). Both marine and non-marine facies are treated,
with only
marine assemblages in Early Palaeozoic times, and more and more
terrestrial
assemblages in Late Palaeozoic times. The Devonian is at a major
turn
because of strong discussions on the nature of the Old Red
Sandstone facies
(ORS) all over the world. Better established correlations between
marine
and non-marine facies are exemplified in the East Gondwanan
Realm
(Australia-Antarctica) and in the more classical East Laureuropean
(Laurussian, Euramerican) Realm.
Individual contributions on topics of special interest, deduced
from new
data, are also included in the FSR.
All these results are the conclusion of dynamic five-year
collaborative
activities between so-called developed and third world countries.
The
appended (preliminary) Final Publication List of IGCP 328 includes
nearly
800 references of refereed papers, abstracts including those given
at IGCP
328 sponsored meetings or at relevant ones, collective and
authors' books,
symposia volumes, articles, newsletters (Ichthyolith Issues), book
reviews
and others. A revised and completed version of this list will be
finalised
for the scientific committee meeting of Unesco IGCP and will be
available
at the beginning of 1997.
Meetings
Several meetings have been organised and/or attended this last
year by IGCP
328 participants. They include the IGCP 406 (Circum-Arctic
Lower-Middle
Palaeozoic Vertebrates) workshops as well as other symposia.
- Uppsala, Sweden, 30 May - 1 June 1996: Greenland workshop;
- Edmonton, Canada, July 11-12, 1996: Canadian Arctic
workshop;
- Rochester, USA, August 4-9, 1996: Silurian workshop at the IInd
Silurian
International Symposium;
- Tallinn, Estonia, October 7-12, 1996:
Laurentia-Barentsia-Siberia and
East Laureuropa workshops, in connection to the IIIrd Baltic
Stratigraphical Conference;
- London, UK, September 29, October 2, 10, 1996: UK workshops;
- Monash University, Australia, October 23, 1996: East Gondwana
workshop.
Important New Results
In this final year new collaboration has begun on the Devonian and
Permian
of South Africa including Australians and two South African
students. A
probably Middle Devonian Malvinokaffric assemblage of sharks,
acanthodians,
placoderms and sarcopterygians similar to that in Antarctica has
been
recovered from the Bokkeveld Group. American-Australian
co-operation has
also begun on Early Silurian thelodonts from Wisconsin-Madison.
New
Carboniferous faunas have been discovered in Argentina.

Last words
It has been a great experience to coordinate activities of so
many
enthusiastic scientists under the banner of UNESCO/IUGS/IGCP. Dr
Gavin C.
Young (Australian Geological Survey Organisation) was instrumental
in the
formulation of the initial proposal He co-ran the project from
1991 to mid
1993 and has been supportive of the current co-leaders throughout.
We thank
especially the IGCP and IUGS secretariats and national IGCP
committees for
all their support - financial and otherwise. Numerous other
organisations
and individuals have assisted the project, especially the hosts to
our 5
major meetings, M. Marius Arsenault, Directeur du Parc de Miguasha
and the
Québec Government (1991); Professor Michael House, Chairman
of the SDS (our main co-operative partner) and the committee of
ISMDEOR, Guilin, China
(1992); Professor Otto H. Walliser and the staff of Göttingen
University
IMGP (1993); Dr A.Yu. Rozanov, Dr and Mrs Oleg Lebedev and the
staffs of
the Paleontological Institute, Moscow and Ukhta Geological
Exploration
Institute (1994); and the Directeur and staffs of the
Muséum National
d'Histoire Naturelle, Paris, and the University of Lille,
Laboratoire Pal.3
(1995).
Our meetings have been times of stimulating and often heated
discussion,
mainly when regarding hotly debated problems such as
conodont-vertebrate
relationships, original environments of the ORS,
stratigraphical
correlations to the standard conodont scales within Devonian
siliciclastics, nature of palaeotissues in teeth and scales (and
their
homology through the whole vertebrate taxa), etc.
Through workshops, poster sessions at other conferences, and field
work we
believe that the aims we set and chief directive of the
scientific
committee to educate have been fulfilled and that the process to
utilise
microvertebrate remains in geology will continue. To this end
students,
from undergraduate to doctorate level have been trained and
microvertebrate
studies are extending.
"IGCP 328 has lived, welcome to IGCP 406." The latter is
considered as
partly successor of the former. However, IGCP 406 will focus on
both micro-
and macro-vertebrates from mainly Ordovician to Devonian series.
It is
devoted to the Circum-Arctic areas where numerous problems have to
be
solved and where IGCP 328 carried out two successful field seasons
in 1994
and 1995. For instance, what have been the palaeogeographical
relationships
of the Timan-Pechora region (TPR) in Early Palaeozoic times?
Recent
re-investigations of geological and palaeontological data
indicate
affinities with either northern Baltica or with Siberia, although
it seems
clear that the TPR was linked to the Old Red Continent in Devonian
times.
Vertebrates have a major role to play in this debate which has
been
initiated during the 1996 Silurian and the Tallinn workshops.
Throughout 1995 and 1996 we have been planning to formulate a
proposal for
a successor project to carry the microvertebrate work into the
Mesozoic,
examining especially the economically rich Late Permian to
Triassic areas
of the world. We hope to submit this proposal in 1997.
