Description
Scan of my upcoming Confuciusornis dui illustration. Soon she'll be whole again, as I tragically ran out of room in my notebook and had to continue her pintail feathers on the opposite pageI say "she"--several authors have argued that contrary to popular belief, confuciusornithids were not dimorphic, but presence or absence of pintail feathers was based on age, molting or both.

Well, Confuciusornis dui does. In fact its one of the very few Mesozoic birds that actually preserved a soft tissue beak, not just the underlying bone (which is straight, only the keratin part is curved). In the finished drawing you'll notice I changed this to C. sanctus and straightened the beak out. No beaks are preserved for C. sanctus proper, but a straight beak is known in Eoconfuciusornis, which I reckon is probably the same genus and/or species anyway. So, some Confuciusornis species had straight beaks, some curved.
