colours, so to compare what mamals do and use it as a basis to support your
argument seems tenuous...(but I will accept a premise of dinos with gaudy
posterioirs a la mandrille %^) )

They could have, but do large birds sport large feathers? Do they (ugh!)
*scale up* with size? If yes, where are the large tyrannosaurid feather
fossils or impressions (or any other?) If no, why bother growing gaudy
"micro-feathers" when you have skin which (by your inheritance) could
possibly do the same job?
