    :soapbox:a pedantic observation:

    It is preserved eumelanin in the shape of the ink sac and not an actual ink sac.

    Is it something you see in the fossil that led you to this conclusion? :hmm:

    In a general discussion I would call it a fossil of an ink sac, but if I got frisky (pedantic), like early this morning...

    :lol: Pedantic observations are probably needed in the field of paleontology...to help balance out all the vividly imaginative observations. :heee:

    Picky, picky, picky :grin:

    eumelanin = melanin = pigment from the ink?

    In the shape of an ink sac :smile:

    Also known as sepia! Eumelanin is black to brown pigment, pheomelanin is yellow to reddish brown pigment.
