"Does anyone think that ceratopsians used
their frills as thermoregulatory devices? In the animals with open frill 
fenestrae,  the flesh would certainly act as a better conductor of heat than  
bone."


There was a paper out there that proposed it, using Triceratops, and Oxygen 
18/19 isotopes if i recall right. Is a possiblity that one of the functions was 
for cooling the beasts down. Though any appendage or  anything sticking out of 
the head or body can work as a radiator. There is probally another 
thermoregulatory paper out there as well dealing with ceratiopsians as well.  
Though the main use was probally sexual display & dimorphism and defensive 
uses, and killing therapods :) .
