BRADYCNEME, NUTHETES, WYLEYIA
A few comments on European theropods...
Yes the tibiotarsi (what's known of them... they are only distal
ends) named by Harrison and Walker as _Bradycneme_ and
_Heptasteornis_ are completely fused and I don't think they are from
dromaeosaurids (or from troodontids). Can't say much more here as
there is work in the pipeline.

Angela Milner has reexamined _Nuthetes_ and presented results at the
Purbeck Limestone meeting earlier this year. _Nuthetes_ is a
dromaeosaurid! Incidentally, the 'granicones' regarded by Owen
(1879) as part of _Nuthetes_ have in recent years been referred to
_Echinodon_ as this taxon has been considered a possible basal
thyreophoran. Sereno (1999) and Barrett (1999), however, show that
_Echinodon_ is a late-surviving heterodontosaur... so, could
heterodontosaurs have been armoured?? Or might this mean that the
referral is still not correct.
> Does anyone else agree on the enantiornithine identity of Wyleyia
I examined _Wyleyia_ (BMNH A3658) for my thesis and I think it's
avian. It has a prominent bicipital crest, a proximal ligamental
furrow and a distal brachial depression. Haven't yet seen the latter
features in a non-avian theropod, but this probably owes more to
insufficient published descriptions. However, while the lack of
pneumatic foramina suggest it *may* be enantiornithine (Cyril Walker
now favours this interpretation (Walker 1991)), Kurochkin (1995)
suggested it could be from a palaeognathan. Certainly small, whatever
Finally, and this is for Nick Pharris and anyone else pondering over
ischial structure in coelurosaurs, _enclosure_ of the ischiadic
foramen or notch can occur within Coelurosauria. I say this
based on a specimen currently in press: more details when it sees
publication (keep an eye on _Can. J. Earth Sci._).
