Ha the Daily Mail version says 155 Million years!

Apparently the odds of finding something like an ink sac unfossilised according to the evolutionary scientists is a billion to one, a nice find then.

Best of all it includes a photo of the drawing of the squid made using the actual ink from the sac.

If anyone thinks that ink is 155 million years old........seriously.........
