Dear Bendeguz,
Cuttlebones aren't all that commonly found, but they do survive archaeologically, for example at Akrotiri-Aetokremnos on Cyprus. I'm afraid I don't have a copy of that report, but you can read the abstract here:
http://triton.anu.edu.au/issue_11.htm. Fragments of cuttlebone were also reported at Balakot, Pakistan - you can read that report here
http://www.persee.fr/web/revues/home/prescript/article/paleo_0153-9345_2005_num_31_1_4787There was a short article about cephalopods and archaeology in Circaea in 1996 by David Smart, which may be read online here
http://www.envarch.net/publications/circaea/12.2/12-2-smart.pdfI'm afraid I don't have a copy to hand to check, but I would expect there to be something on the subject in Ken Thomas and Marcello Mannino's contribution to D R Brothwell and A M Pollard's (2001) Handbook of Archaeological Science (pp427-441).
Offhand I don't know of any cuttlebone moulds that have been recovered. I'd be interested in hearing of any reports .
I hope that's some help
Matt
