Talk:Aucasaurus

Size?

On the Discovery Channel dinoviewer, which presents dinosaurs from the documentary program, Aucasaurus is described as being 13 ft long, 3 ft tall, and about 1500 lbs. However, when you go to the scale section an adult is 20 ft long and at least as tall as a 6 ft tall man. Explanation please? —Preceding unsigned comment added by 76.102.116.90 (talk) 07:23, 20 December 2008 (UTC)

Dinosaur inflation? The dinoviewer sounds more accurate, as the only known specimen is supposed to be a little over 4 m long. J. Spencer (talk) 16:38, 20 December 2008 (UTC)

Most scale charts online are just completely wrong because no thought goes into them. I see a lot that takes a picture with a weird pose say, bent tail or non-lateral perspective, scales the length of the picture (not the animal) to a person, and it comes out big because they didn't account for the fact the tail was bent!

That makes sense; It is interesting to me that there was a three foot tall tyranosaur-like theropod at all. Wouldn't it have to compete with the faster and supposedly smarter dromaeosaurs? How do we know that "aucasaurus" was not just a juvenile of an already identified theropod? —Preceding unsigned comment added by 143.246.219.162 (talk) 23:41, 15 February 2009 (UTC)

Actually, it looks like Aucasaurus is the only small predator known from the upper Rio Colorado formation (Velocisaurus lived a bit earlier I think). Anyway, the southern hemisphere dromaeosaurs appear to have been pretty different from the northern ones. They were probably fish-eaters, with specialized long, slender snouts. Sort of heron/spinosaur-mimics. Dinoguy2 (talk) 00:11, 16 February 2009 (UTC)

Makes sense; if you want to see what I'm talking about, go to the dinoviewer on the Discovery Channel website and go to aucasaurus' page. —Preceding unsigned comment added by 96.231.145.245 (talk) 19:26, 11 April 2009 (UTC)

No perspective issues there. I can't find any sources for a length estimate for this species. One or both of those numbers must be wrong, including the unsourced statement in our article here. Note that the fact file also says it was a "member of the Abelisaur genus," showing htat whoever wrote it had no idea what they were talking aboutDinoguy2 (talk) 20:49, 11 April 2009 (UTC)

Check the original description by Coria et al., they don't explicitly give a length estimate but the paper has scaled pictures of the hindblimb, forelimb and preserved portion of the tail. If you use these dimensions to scale the reconstructed skeleton diagram provided in the article, it appears that the length is just over 4 meters. ArthurWeasley (talk) 05:54, 12 April 2009 (UTC)

skull damage

I can find a reference to the bit skull idea in 2007's "Walking on Eggs" by Chiappe and Dingus (Google Books), but I am 99% certain it predates 2007. It's probably in another semitechnical book about (or mentioning) Auca Mahuevo. J. Spencer (talk) 00:38, 21 January 2011 (UTC)
