Screenshot of a Bluesky post of a fossilized cuttlefish that looks like a dickhead and part of a shaft. The scientist claims it was carried around by prehistoric humans 250,000 years ago and we don't know why, but they will talk about why in an episode of the podcast The Fossil Files
Haven't noticed anyone say anything about this yet but cuttlefish bones are flat thin discs. They sell them in pet stores as a calcium supplement.
Not a comfortable phallus if used in that way.
Cuttlefish is not really the best term for it. It's actually a nautiloid that has a straight cone shaped shell. When living the fleshy part would have looked similar to a cuttlefish. The fossil is very fragmented too.
