Can anyone help with identifying this object please?

[stimmchen@fedifreu.de]

@thebaywindowgirl Not an expert at all. But to me it looks like some kind of sponge.

[chaharper@mastodon.scot]

@thebaywindowgirl I've read the it could be any kind of marine mammal such as a a whale or a dolphin but that at that size probably a young mammal. If that adds...

[bashstkid@mastodon.online]

@thebaywindowgirl I’d guess at dolphin epiphyseal disc?

You’d need to ask a zoologist about the functional adaptations of the ancestral spine to living in water rather than land re weightbearing etc.

@thebaywindowgirl macaron?

[thebaywindowgirl@toot.wales]

@helenclayton If only

[mahxiac@esperanto.masto.host]

@thebaywindowgirl it definitely looks like a spinal bone of some sort. But I don't know enough for a positive Id of the species. The fact that it is round the way it is makes me think that it is very weathered and thus more difficult to identify.

[sheepnik@toot.wales]

@thebaywindowgirl @helenclayton I thought it was a fossilized crumpet.

[helenclayton@mas.to]

@sheepnik @thebaywindowgirl shows how we think

[tekguru@social.vivaldi.net]

@thebaywindowgirl Fossilised sea sponge?

[thebaywindowgirl@toot.wales]

@sheepnik @helenclayton I’d be very disappointed if someone offered me a crumpet that thin.

[sheepnik@toot.wales]

@thebaywindowgirl @helenclayton It may have got squashed over the millennia.

[helenclayton@mas.to]

@sheepnik @thebaywindowgirl they are pretty squashy.

[dtl@8bitorbust.info]

@thebaywindowgirl it definitely looks like bone.

[dtl@8bitorbust.info]

@thebaywindowgirl @PaoloViscardi might be able to help ID it.

[thebaywindowgirl@toot.wales]

@sheepnik @helenclayton Fair point.

@thebaywindowgirl @qpocooriginal

Is it known whether the identification by this auction house is correct?
that it s #whale #bone and not #petrified #wood?

[xenophora@mastodon.art]

@STimmchen @thebaywindowgirl

I would've guessed coral. Still cool, though.

[jakobtougaard@mastodon.online]

@sebastian @thebaywindowgirl I agree, looks like the epiphysis of a whale vertebra. From a younger individual, where they are not fused with the main bone of the vertebra.

[cathos@merveilles.town]

@thebaywindowgirl looks kinda like the bones of some coral species. Also reminds me of a sand dollar.
