This week I have another real mystery object for you to have a go at identifying. This was dredged off the sea floor, on the extreme western edge of the European continental shelf where it meets the Atlantic Ocean:
There are a few possibilities, so I’d be interested to hear what you think. You can leave your suggestions, observations and questions in the comments box below.
Have fun!
Zygoma 
The sunken remnants of a very, very nasty trade?
Seems a dental element of a tall and hairy extinct pachyderm
So it might be a tooth? My first thought was horn, or walrus tusk. But since the first two responses are suggesting elephant tusk, I’ll go with that.
Why couldn’t it be horn dagnabbit? A nice big ruminant horn? I’ve seen smaller horns look pretty much like that.
My first thought was pachyderm but the hollowness makes me think big bovine horn.
goo goo g’joob ?
dental extension, not cranial projection.
Looks like a bovid horn sheath to me. But what one? Poking around,looks like an ox ,and found that vikings used them as drinking horns. Amazon has replicas for $46.
The time has come, ————–, of ships and seas and sealing wax….
Here’s a look at some dental extensions – https://www.fws.gov/lab/ivory_natural.php
Certainly a tusk although it is not easy to distinguish the enamel and dentine layers on the photo of the section. It is way to straight for a Mammoth. Could be Elephant but even if Paolo might have large hands, it is difficult to handle the base of an elephant tusk with one hand. The section is oval, the wall of the root not very thick. I suppose this tusk belongs to one walking on it.
