There's a story on BBC today implying that a preserved fossil squid was found with an intact ink sack. I have a little trouble with that. That there was ink-impregnated rock I could believe. They could grind up a little to retrieve ink. But for a sack to remain full of mucus as the whole area mineralized seems far fetched: The sack should have mineralized too. So either there's something amazing afoot, or the reporters didn't get it right. I'd bet the latter.
