robustus or piscator?

[Hebert Bruno Campos <hebertcampos@bol.com.br>]

I like to point two questions:

1. Is '_Anhaguera piscator_' (Kellner& Tomida, 2000) named 
_Coloborhynchus robustus_ or _Coloborhynchus piscator_?

Veldmeijer (2003a, p. 99) stated: "It is also relevant that the 
premaxillary crest in _A. piscator_ runs all the way to the anterior 
aspect of the skull (contra Kellner& Tomida, 2000). Additional support 
is provided by the flat, thought small, anterior aspect of the skull 
from which two teeth project are the positioned more dorsally relative 
to the subsequent teeth. It is beyond the scope of this work to discuss 
the classification of this specimen in detail but the large size alone 
(the juvenile specimen is as large as for instance the adult _C. 
spilbergi_) points to a new, largest known species of the 
_Coloborhynchus_ and is therefore referred to as _C. piscator_."

However Unwin (2002, p. 241) observed: "Frey & Martill (in press) point 
out that the holotype and only known specimen of '_Anhaguera piscator_' 
(NSM-PV 19892) is identical to the two specimens representing 
_Coloborhynchus robustus_, an opinion which is supported here. 
'_Anhaguera piscator_' is thus treated here as a junior synonym of 
_Coloborhynchus robustus_."

2. Is the Anhagueridae an valid name? Or this is an synonym of the 
Ornithocheiridae?

Unwin (2002) affirm that the name Anhagueridae is an synonym of 
Ornithocheiridae. However the Anhagueridae yet is used (e.g., 
Veldmeijer, 2003b) as a valid clade.
