    Anyone (other than TTF and Phil) want to guess what the attached image is? Yes, it's from a cephalopod, but that's the only clue.

    I've deliberately textured the image (bricks) - sorry everyone, but this one is embargoed.

    its obvious that theyre the initial stage of an octoparrot's feathers....


    hmm... i dunno... maybe some type of velcro type appendages on or around the suckers used for a better grip?

    Well, they look like dermal denticles of sharks, so i searched for dentacles on tonmo, and the answer is on this very site i believe :)

    Richard Ellis' review of "the BEAST" mentions microscopic denticles on the tongue of an Architeuthis...

    is this the answer?

    Cheers,

    Thomas.

    This is the kind of answer I was expecting (and what others may-well have assumed in the fossil record also), but it's not the right answer.

    Exactly what is a radula?
    What exactly is a 'denticle'?
    What is the tongue of an Architeuthis (or any mollusc)?

    No, these are not radular [adj.] structures, and not associated with the 'toungue'. but you're warm.

    It's pretty sensational stuff!

    Hi Steve,

    Are they esophageal teeth?

    Is it the nacreous layer of a nautilus shell? :P

I am, in short, a man on the edge of everything."

    You haven't forgotten the face of your father John !

    I did see a photo of a similar looking structure, but as was mentioned before, it was a skin surface from a shark... :(

    Hmmm, tongue was my only guess, same reference as Thom's (Richard Ellis book)... but I've got nothing else; I'm stumped... wonder what species this is... (request for hint fully embedded)

    Usually only hard parts of animals are fossilized.

    Cephalopod Hard Parts:
    1. External Chambered Shell
    2. Internal Gladius/Pen/Rostrum
    3. Aptychus (Jaws, Beak, Opercullum)
    4. Radular Elements
    5. Tentacle hooks/Sucker Rings
    6. Statoliths

    I'll choose tentacle hooks just to choose something :)

    Unless someone can add something to the list :shock:

    Sorry to keep texturing these things; the reasons will become all-too apparent in Tonmo time.

    Attached is a radula (textured); nope, the earlier image is no radula; neither is it hook, shell nor of gladius origin. People have been warm .... but you'll need to do a lot of digging to find out what these structures are, because as far as I know they really haven't been reported in detail to date.

    I don't want to tell you what it is, simply because it's an interesting way to learn about anatomy if you figure it out for yourself (boring if I blurt something out, don't you think?).

    Dear Steve,

    Well...gah. Structures for pulping food and moving them down the gullet, I guess. If you didn't have grinding teeth or a radular tongue, you might want some kind of internal structure to grind up the food before it was digested.

    Ah, I've got it, you found a Sarlacc.

    :wink:

    Is it a piece of the interior lining of the gizzard of a rainforest nautilus? Because that's what it looks like.

    guess

    Hi this is definitely a guess, well first picture would have said radula but has it is not, i have no idea is the picture up side down lol. The second picture guess again is it some kind of cilia in the digestive tract.
    :bugout:
