Updated May 25, 2015, with a new image of Nundasuchus featuring more elements .
A new paper
by Nesbitt et al. 2014 describes a Middle Triassic archosaur, Nundasuchus, they nested close to Ticinosuchus using Nesbitt (2011). Nundasuchus is also basal to all “pseudosuchia” (phytosaurs, aetosaurs, crocs, rauisiuchians, etc., but not Euparkeria or Proterochampsidae using Brusatte et al. (2010).
In the large reptile tree Nundasuchus also nests with Ticinosuchus, but not basal to all pseudosuchians. Nundasuchus is also a sister to the clade Arizonasaurus + Qianosuchus + Yarasuchus and to Decuriasuchus.
Although represented by only a few bits and pieces (Fig. 1), enough is known to firmly nest Nandusuchus.
