Paul Davies recently finished a PhuD at Bristol Uni which included a look at
the taphonomy of some dead shorebirds which he staked to various littoral
zones of a lagoon environment in Florida (no sub-tropical lagoons in
Blighty, more's the shame) to ask and answer all sorts of stuff relevant to
Achae. There should be a paper by now (maybe Mike Benton or Jeremy Rayner
know what the story is). He gave a paper at the 1992 V.Pal conference in
Bristol (organised by Mike Benton), so there should at least be an abstract.
At the risk of being a swamp publicist, I will mention that included in the
Eichstatt Conference that Jeffrey refered to (and which should really be a
first stop for anyone interested in this sort of stuff) is a paper by Tony
and Tim which tossed up an alternative to the more familiar theories:
Thulborn, R.A., and T.L. Hamley, "A New Palaeoecological Role for
Archaeopteryx", in "The Beginnings of Birds; Proceedings of the
International Archaeopteryx Conference Eichstatt 1984", eds. M. Hecht, J.
Ostrom, G. Viohl, & P. Wellnhofer, pubs Freunde des Jura-Museums Eichstatt
1985, ISBN 3-9801178-0-4.
"Archaeopteryx is envisaged as an agile hunter that frequented shore-lines,
pools, and shallow waters. It probably subsisted on prey of moderate size,
including small fishes and worms. The feathered forelimbs ("wings") may
have been used as a canopy while Archaeopteryx foraged in water; its hunting
techniques may have resembled those used by existing herons and egrets.
Speculations on the natural history of Archaeopteryx prompt a new theory for
the origin of avian flight: the first flying birds may have been aquatic
forms, using their rudimentary flight apparatus to carry them from
wave-crest to wave-crest."
It might amuse...
