PAL ASS 2002 ABSTRACTS
Newsletter 51 (2002) of The Palaeontological Association
arrived a short while ago and includes the abstracts for the
46th Annual Meeting of The Palaeontological Association.
This meeting will be held 15th-18th December 2002 at the
University of Cambridge. Of interest to this list are the
Jackson, S. How to make dinosaur tracks: interpreting
dinosaur footprint formation and preservation using
laboratory controlled simulations.
Tracks. 'Nuff said.
MacEwan, V. Application of high-resolution computed
tomography in palaeontology: analysis of a Middle
Devonian labyrinthodont tooth from New York State, USA.
The term 'labyrinthodont' seems to be used here as a
morphological descripter, not as a group name.
Milan, J. & Bromley, R. G. The influence of substrate
consistency on footprint morphology: field experiments
with an emu.
More tracks. This will presumably be similar to the talk on
undertracks Jesper gave at SVPCA '02.
Norman, D. B., Crompton, A. W. & Charig, A. J. The
cranial morphology and systematics of the enigmatic basal
ornithischian _Heterodontosaurus tucki_ Crompton and
As some of you may recall this talk was advertised for
SVPCA but wasn't given in the end. The abstract is just a
brief review of the history of _H. tucki's_ discovery and
notes that detailed accounts of the morphology are needed.
While heterodontosaurs are consistently regarded as basal
ornithopods, Norman et al. say that reanalysis 'has provided
an opportunity to reassess (_H. tucki's_) systematic position
Clack, J. A. & Ahlberg, P. E. A new stem tetrapod from the
mid-Carboniferous of Northern Ireland.
A partial left jaw discovered in 1843 and described as a
rhizodont is a new taxon of primitive tetrapod. It is of
_Whatcheeria_-like grade and less derived than
_Crassigyrinus_, _Greererpeton_, anthracosaurs,
Clark, N. D. L. Tracking dinosaurs in Scotland.
Tridactyl tracks from the Duntulum Fm (Bathonian)
represent medium to large bipedal forms.
Corfe, I. J. & Saila, L. K. Questioning the tetrapod diversity
of a Jurassic island, Glamorganshire.
Same as presentation given at SVPCA.
Jones, M. E. H., Evans, S.E. & Ruth, B. Ontogenetic
variation in the frog ilium and its impact on classification.
Anuran ilia are employed heavily in classifying fossil
anurans as they are generally the best represented elements.
But does their diversity reflect true diversity or represent
ontogenetic stages? Studies of bufonid and hylid ilia show
that the diagnostic features seen on anuran ilia generally
don't change with ontogeny though some subtle changes in
acetabulum shape, shape of dorsal tubercle and other
features were observed.
Lipkin, C. & Sereno, P. C. A spinosaurid furcula and its
A _Suchomimus_ furcula is flattened and V-shaped with a
tongue-shaped hypocleidium. Overall it resembles the
furcula of _Allosaurus_. The specimen found with the
furcula is a new one discovered in 2000.
There's another abstract on tracks but I've run out of time.
