@OnTheWayOut. Yes, the ink sac was fossilised. The team involved in the discovery as a bit of a publicity stunt extracted a sample and (as far as read) dissolved the ground up sample in ammonia solution; they then produced a picture of the 'squid' using this prepared ink.
Perry, I am unsure who you think these articles you copy and paste are going fool? In both cases (the 'squid ink' and 'eggs' debacle) on this thread, your sources are deliberately misleading. Why are you happy spreading this kind of obvious misinformation? Is honesty not a virtue?
