    This to me seems like one of the most impressive efforts so far, check out the ammonite with a sense of humour in the trailer at 00:38 :goniatite

    And they've got Tusoteuthis, judging by the pictures...

    Too cute! I might just have to drag myself to the science center to watch the whole thing...

    Very nice! it is always good to see cephalopods in sea monster movies. :grin:

    I dont know about the dark ink and the white shell being too compatible.

    Also see the 3D tusoteuthis (another link hidden on this thread (post #25)) :wink:

    I saw the imax the other week and it was well worth it. The creatures were pretty realistic and you cannot go wrong with throwing squid and ammonites in the movie.

    Are ammonites thought to have possessed an ink sac??

    I highly recommend this movie.

    If (when) I find some extra cash for a book, I will be better able to answer that question.

    From the description on amazon:

    highlights include new evidence for the existence of an ink sac in fossil ammonoids

    This prompted me to wonder if Spirula has an ink sack. Answer from TOLweb: "Radula absent. Ink sac reduced." The ink sack's consistent, the lack of radula seems wacky; I've never heard of a ceph with no radula before. But then again, I've never asked.

    These authors seem to think the ink sac from the ammonoid mentioned below could be just remains of the "Black Layer" or other black deposit like those of modern nautilus. The black layer is made of the same "excretions of metabolic waste like cephalopod ink which all contain melanins"

    I like how they made the tusoteuthis.
