RE: Dinosaur mass table online

At least Matt Wedel has posted some comments on this topic of mass estimation 
based on simple volumetrics over at SV-POW! Some of this has been published, 
but topics such as the mass-savings of airspace reduction when taking 
pneumatization into account in internal structures, as well as the dynamic 
volume of the pneumatics (potentially inflatable, as is variable in birds in 
life), etc., all concerns that influence volumetrics that _PDW_ does not
