With the preliminary reports that Aucasaurus is a more regular abelisaurs with a longer skull and arms, is it true that only Carnotaurus appears to have those highly aberrant features: The degradation of the Fore arms and the facial contraction. Would you all have any explanation for the teleology of these apparently maladaptive traits for a carnivorous theropod. Sexual selection is a straight forward excuse but is there anything else that appears suggestive? thanks EA _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
