Ornithischian Lungs???

[MariusRomanus@aol.com]

I've been trying to reach a conclusion as to what sort of lung Ornithischians 
possessed. There's always so much attention paid to theropods and sauropods 
in this regard. Everyone else is left out. I've seen Perry's argument about the 
retroverted pubes supporting an abdominal wall muscle that vetilated the 
lungs, but I was wondering what other ideas, if any, are out there. What I'm 
really striving for are ideas on their aerobic capacities. So, any help 
whatsoever 
would be much appreciated.

Thanks
