Perhaps this is why _Compsognathus_ and the Solnhofen pterosaurs are 'naked'
- unlike their fuzz-covered cousins from Jehol and Karatau. An insulatory
body covering might have been unnecessary in the warm, muggy conditions of
Late Jurassic Europe.
If Archie didn't
get any aerodynamic benefit for such an extensive frond of tail
Gatesy and Dial (1996) suggest that Archie's rectricial 'frond' served more
for stabilization than maneuverability.
