pachycephalosaurs

[frank bliss <frank@blissnet.com>]

Since humans loose 40% of their body heat through their head during the 
winter, what better mechanism for heat transfer than investing in a 
spongy, blood rich, honeycomb skull cap.  The extra vascular supply 
could be very effective in moving heat away from the body for 
Pachycephalosaurs.  Why invoke the head butting hypothesis for the 
investment in bone mass. Heat transfer is an excellent reason.  
Additionally, such "decorations" (excessive body growth)  are used 
widely in the modern animal kingdom as sexual markers.  The comb on a 
rooster is just an example.  Either explanation is a better hypothesis 
than the head butt.

BTW, I just pulled out the first Pachy skull cap out of my newly 
discovered Hell Creek bone bed.  It is just the bony cap with no spines 
but impressive none the less.  I now have three sites on my own land to 
hunt the big fellas.  (2 microsites) Paleontological nirvana! (Bliss)
