working on Middle Devonian vertebrate
material from Scotland and Orkney.
Research started in 1974, collecting not only
articulated material but also disarticulated
material from non-fish beds. More specifically
the latter included coprolites, hundreds of
which have been thin-sectioned revealing the
prey, mainly acanthodians but also
invertebrates. Proper identification of the
acanthodians was difficult because of lack of
detailed information on scales etc. from
literature. In order to fill this gap, we started
destructive investigation on articulated
specimens: making serial thin sections of
spines and scales. Of great value was
articulated fossil material from the Moray Firth
area donated by Bob Davidson [See previous
Ichthyolith Issuesand Burrow below - ed]. It
is this part of our research that will be
published in the near future. Regional
information concerning the distribution of
coprolites and their contents will follow the
publication.

Alain spoke about Severnaya Zemlya
heterostracans at Jurmala - co-operative work
with Valya Talimaa. Following the meeting he
went to Lithuania. He writes: My stay in
Vilnius was very successful. I have
heterostracans from all over theRussian
Arctic to work on! Severnaya Zemlya + Timan-
Pechora and others. I will certainly need a
second life ...
In his report to IGCP406 this year Alain
writes:
The French Group of IGCP 406 (A. Blieck, P.-
Y. Gagnier & D. Goujet) has mainly worked on
the taxonomy, biostratigraphy and
palaeobiogeography of Devonian vertebrates
from the Canadian, European (Spitsbergen),
and Russian Arctic:
1)heterostracan pteraspidomorphs from the
Lower Devonian of Severnaya Zemlya
(Russia);
2)acanthodians from the Lower Devonian of
the Mackenzie District (NWT, Canada);
3)placoderms and thelodonts from the
Lower Devonian of Spitsbergen. Most
results confirm close
palaeobiogeographical relationships
between the "northern" margin of the Old
Red Sandstone Continent (Canadian
Arctic), the Barentsia block
(Spitsbergen), the Kara-Tajmyr block
(Severnaya Zemlya), and even with the
northern part of Siberia (Central Tajmyr
and Noril'sk region).
