Before I start, question for Nick: what is the source for the Phil
Currie phylogeny you discussed where sinraptorids were possible
close relatives of abelisaurids and _Giganotosaurus_? I didn't know
that stuff had been published yet.
On _Chilantaisaurus_, Tim Williams says...

I think we can say that they *certainly* do not belong in the same
genus: _C. tashuikouensis_, the type species, is probably a
non-coelurosaur (a megalosauroid or a spinosauroid?), while _'C'
maortuensis_ was referred to the Maniraptora by Dan Chure (1998).
Chure cited reduced number of maxillary teeth, small and fused
maxillary interdental plates and (among other features) a highly
pneumaticised basicranium. This was in the JVP 18 abstracts volume -
does anyone know if Chure is publishing a paper on the subject? And
seeing as _'C' tashuikouensis_ clearly deserves a new generic name, I
wonder if Dan Chure is going to give it one.
On the subject of theropods and their phylogenies, why has no one yet
done a listing of the contents of the latest ish of _JVP_. Talk about
dinosaur palaeontology as a burgeoning science!

nodosaurids and most other dinosaurs did theirs"
