[edit] Rauisuchid or poposaurid?

The Rauisuchidae page lists Postosuchus as one of the genuses belonging to that family, but here it says it belongs to the Poposauridae. Which is right? Jerkov 11:02, 29 May 2006 (UTC)

Traditionally Postosuchus was considered a rauisuchid, but Paul Sereno 2005 defines the Rauisuchidae as "The most inclusive clade containing Rauisuchus tiradentes Huene 1942 but not Aetosaurus ferratus Fraas 1877, Prestosuchus chiniquensis Huene 1942, Poposaurus gracilis Mehl 1915, or Crocodylus niloticus Laurenti 1768. --Firsfron 16:43, 29 May 2006 (UTC)

The groups Poposauridae and Rauisuchidae have been confused since Chatterjee's 1985 paper on Postosuchus, which he names a poposaurid. However, his discription is based on 3 separate taxa, 2 of which, were poposaurids. Thus Postosuchus is not a poposaurid, but what would be considered traditionally, a rauisuchid. —The preceding unsigned comment was added by 70.185.144.231 (talk • contribs).

You may be right, but you're going to need to publish this before modifying the article. This is an encylcopedia, not the JVP.Dinoguy2 17:58, 26 November 2006 (UTC)

[edit] Largest Triassic Carnivore?

I remember in Walking with Dinos the Narrorator guy says Postosuchus was the largest carnivore on earth. Give the "You-are-there" feeling of the program I assume he ment the Largest Carnivore of the Triassic. Is this true? Was Postosuchus the largest carnivore of the triassic? In North America yes but there were larger carnivores than Postosuchus
