 A big monograph came in the other day:

 Pereda-Suberbiola, Javier. 1994. Polacanthus (Ornithischia,
    Ankylosauria), a translantlantic armoured dinosaur from the
    early Cretaceous of Europe and North America.
    Palaeontographica Abt. A   232(4/6):133-159.

A nice monograph that seems rather relevant to the current list
discussions. JP-S redescribes the genus and finds it to be distinct
from Hylaeosaurus but confirms that Hoplitosaurus is really Polacanthus
based on the humerus, femur and armour. Gives Pol. an intercontinental
distribution and supports connection between Europe and NA during the early
Cretaceous. Seems like nice work but, of course, I ONLY SKIMMED IT. 8-)

We finally got the paper mentioned earlier (by Mikiel? maybe?):

XP-S, H. Astibia & E. Buffetaut. New remains of the armoured dinosaur
   Struthiosaurus from the late Cretaceous of the Iberian Peninsula
   (Lano locality, Basque-Cantabric basin). Bull. Soc. geol.
   France   166(2):207-211. 1995.

lower jaws and cervical material make up the new material who also
discuss the significance of variability and its possible sources.

If you want to know how it all started there is a big and interesting
paper out on the origin of tetrapods:

Shubin, Neil. 1995. The evolution of paired fins and the origin of
    tetrapod limbs.   Evolutionary Biology   28:39-86.

Fun stuff from a sharp dude. The on-going discussions on the origin of
the five digit plan and the like is great reading and a wonderful area
of current research.

Another neat paper:

Jenkins, Farish A. and a bucket-full of others. 1994. Late Triassic
   vertebrates and depositional environments of the Fleming Fjord
   formation, Jameson Land, East Grrenland. Meddelelser om Gronland
   Geoscience   32:3-25.

Nice exploratory work on a new fauna from the mid east coast of
Greenland. Very Late Triassic and includes a turtle, some temnospondyle
and cyclotosaur amphibs, a whole pterosaur, some mammal teeth, aetosaur
material, scraps of a theropod and a whole prosauropod - the ever
popular Plateosaurus engelhardti. Neat.

And finally more thoughts on volcanism and the Permo-Triassic extinctions
and the like:

Veevers, JJ & RC Tewari. 1995. Permian-Carboniferous and Permian-
   Triassic magmatism in the rift zone bordering the Tethyan margin
   of southern Pangaea. Geology 23(5):467-470

That's it
