"Acro" ribcage dilemma
Just got through watching a taped episode of ?Dinosaur Attack? last night,
featuring Dr. James Farlow and sculptor Dave Thomas (God rest his soul), and
something puzzled me. In the show, Dale Russell suggests something to the
effect that because the ribcage of _Acrocanthosaurus_ was so narrow, the
animal would have relied solely on an anaerobic metabolism when chasing prey
since it would not have had the capacity to inhale much air in times
strenuous activity. That said, that?s about all that the explanation the
viewer got, and so I was just wondering if anyone might be able to elaborate
on this for me. Were there any other theropods that might have exhibited
this adaptation? So far as I know, we all shift gear to anaerobic
respiration in times of physical stress, but not to the same extent as
Russell seemingly proposed for _Acrocanthosaurus_.
Thanks in advance.
