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!

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

I am now a man with no food, with two less fingers and one less toe than I was born with; I am a gunslinger with shells which may not fire; I am sickening from a monster's bite and have no medicine; I have a day's water if I'm lucky; I may be able to walk perhaps a dozen miles if I press myself to the last extremity. I am, in short, a man on the edge of everything."

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:
