Rauisuchid or poposaurid?[edit]

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. —Preceding unsigned comment added by (talkcontribs)

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)

Largest Triassic Carnivore?[edit]

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

Is Postosuchus a dinosaur? (talk) 06:25, 20 January 2008 (UTC)

No, but like a lot of big predatory "thecodonts", it was once thought to be a dinosaur. J. Spencer (talk) 14:56, 20 January 2008 (UTC)

Yeah like said above they were a type of reptilen that was closely related to the dinos it also ate dinos as you may konw Secthayrabe (talk) 13:04, 13 september 2008 (UTC)


"Postosuchus was one of the largest carnivorous reptiles during the late Triassic, reaching up to 4 meters (13 ft) in length and 2 meters (6.5 ft) in height"

That line doesn't make much sense, regarding height, this is a reptile, meaning the tail is close to half the total lenght and at 4-5m it certainly won't be 2m tall at anywhere, the source is incomplete though I could find it (Postosuchus, a new thecodontian reptile from the Triassic of Texas and the origin of tyrannosaurs) but I can't access it to verify such claim.

So I've read the source, what is cited here appears in page 432 but some things are omited here, first, they're based on a very innacurate skeletal and life restoration by today standards (figures 19 and 20) and second, it says that is 2m at the head as standing, what does the text mean by standing? given how its only 1.5m tall at the head in the skeletal it's most likely that is 2m tall in tripod pose. I will remove that part of the text as height in tripod pose is an outdated measure. Mike.BRZ (talk) 21:51, 23 May 2013 (UTC)
Ouch, it certainly wouldn't be able to hold it's head like that. FunkMonk (talk) 22:07, 23 May 2013 (UTC)
