We think that it is a whale or dolphin penis
Many thanks, Ian, for sorting that out. Alistair Gray has sent a comment agreeing - it's a cetacean's baculum or penis bone, found in many placental animals but not humans. Jon
Graham has identified it as "Definitely a walrus tusk. Exactly the correct length and curvature."Which is it? Jon
I have just read that whales don't have a baculum but walrus do.
So is it a walrus' baculum or a walrus' tooth - or something quite different? Jon
You'll need a photo of a cross-section: bone has a particular structure.
The remaining 'tissue', the lack of twist (or screw), and the feature on the tip of the item still tend to point towards the penis. Can you tell whether it was it bone or tooth-like in composition ?
Fibrous attachment suggests not a walrus tooth.
The Raptor writes, "The object is most certainly not bone or Ivory, it is flesh, and in the close up the tip is protruding from a sort of sheath, so it's maybe a horn but it's no unicorn horn."
Definitely looks like the tip of a penis to us, especially now that you say that "it is fleshy".
