Miragaia's Fancy New Neck....



Thanks Tom! Regarding the behavioral speculations so far, my vote would be that 
M's neck was primarily an adaptation for sub-canopy arboreal feeding (which 
means it avoided competition with other low browsers and adult sauropods), but 
as I've said before in regard to such specializations, we should avoid the 
assumption that there was only one benefit, like the old arguments about 
neoceratopsian horns being "just" for theropod defense or "just" for 
intraspecific fighting. (This calls for a cartoon with a Rudyard Kiplingesque 
pterosaur saying to the Stegosaur's Child as it whacks a theropod uncle, 
"'Vantage number two!") -- Mark
