Pycnonemosaurus nevesi and 4-winged dinos

["Tim Williams" <twilliams_alpha@hotmail.com>]

I've seen this critter mentioned on the list, but not the full reference. 
Here 'tis:

Kellner, A.W.A. and Campos D.A. (2002).  On a theropod dinosaur 
(Abelisauria) from the continental Cretaceous of Brazil.  Arquivos do Museu 
Nacional Rio de Janeiro. 60 (3): 163-170.

ABSTRACT:  A new theropod (_Pycnonemosaurus nevesi_ gen.nov., sp.nov.) is 
described, based on five incomplete teeth, parts of seven caudal vertebrae, 
a right pubis (lacking the proximal part), a right tibia, and the distal 
articulation of the right fibula. The specimen (DGM 859-R) was found in a 
red conglomeratic sandstone at the locality Fazenda Roncador (Mato Grosso), 
which is referred to the Upper Cretaceous Bauru Group. _Pycnonemosaurus 
nevesi_ is classified in the Abelisauria because of the expanded distal ends 
of the transverse processes in some (but not all) caudal vertebrae. It 
differs from all other members of this clade by its small pubic foot and 
hatchet-shaped cnemial crest of the tibia. This new taxon confirms the 
presence of abelisaurs in the continental Upper Cretaceous strata of Brazil.


Also, I have not heard this mentioned - and I'd like to get a hold of it:

Padian, K. (2003).  Four-winged dinosaurs, bird precursors, or neither?  
Bioscience 53 (5): 450-452.
