Feathered Theropods -Reprise

["TRUETT GARNER" <DINOBOY@worldnet.att.net>]

Firstly , 
Thanks to Jeff for a very succinct explanation of his viewpoint,( which I
highly respect ) and thanks to Brian for bringing the issue more into focus
. Didn't mean to start a firestorm . My basic problem with feathered
Oviraptorids or Dromaeosaurids has to do with size in both animals . I
understand that Oviraptorids and Dromaeosaurids are considered ' small '
theropods , but are they not both larger than
the feathered theropods from China ? In other words , what is the upper
size limit in which insulation (discounting display purposes)
becomes unnecessary in an endothermic dinosaur living in a fairly equable
environment ?
