pterosaurs

["Norton, Patrick" <Patrick.Norton@state.me.us>]

Thanks to those who responded off list to my query about pterosaur   
insulation.  It appears that _Sordes pilosus_ is generally accepted as   
evidence for a fur-like integument in some pterosaurs, but there seems to   
be little evidence either way for the Pterodactylus species from the   
Solnhofen. That seems a bit odd, given the high quality of preservation   
from those quarries, but is it a fair interpretation of current thinking?
