Nesbitt, S.J., 2005.  A new archosaur from the upper Moenkopi Formation 
(Middle Triassic) of Arizona and its implications for rauisuchian phylogeny 
and diversification.  N. Jb. Geol. Palaont. Mh. 2005 (6): 332-346.

ABSTRACT:  Isolated archosaurian remains consisting of pelvic elements and 
femora from the upper Moenkopi Formation (Middle Triassic) of Arizona are 
similar to the Late Triassic 'rauisuchians' *Chatterjeea* and *Sillosuchus*. 
 The new material is a 'rauisuchian' hypothesized to be more closely 
related to *Chatterjeea* and *Sillosuchus* than to *Poposaurus*, 
*Arizonasaurus*, and other rauisuchians.  The Moenkopi form material helps 
polarize characters for a small group of 'rauisuchians'.  If current 
archosaur phylogenies are correct, then the presence of a *Chatterjeea*-like 
taxon in the Moenkopi Formation indicates that many of the archosaurian 
groups radiated by the early Middle Triassic.

This paper does not name any new taxa.
