Pterosaur beaks

[John Conway <john_conway@mac.com>]

I have noticed that many pictures of toothless pterosaurs (_Pteranodon_ 
etc.) show a small albatross-like hook at the end of the beak. Judging 
from the drawings and photos I have, albatrosses and toothless 
pterosaurs do not have a similar bone structure at the end of the beak. 
Is there any evidence for a hooked beak in toothless pterosaurs? Are 
these restorations even plausible?
