I found this on the north kent coast of the UK close to Margate. Can anyone please identify it - I think it is a fossilised tooth, maybe a tusk or horn, it is heavy like a stone but still has a boney grain to it.
Please see photos for details and feel free to ask any questions.
Many thanks in advance.
That looks to be a very interesting find.
We have to bear in mind that erosion has removed some material, especially from points and edges.
It has some of the characteristics of dinsosaur bone, though I suspect it might have been washed along the shore somewhat (I don't think Margate is known for dino fossils.)
It looks a bit toothy, but the sockets on the base are a problem. I wonder if it might be one of the armouring spikes on the back of a Acanthopholis, one of which was found in Maidstone (http://www.culture24.org.uk/history-and-heritage/art15994, incl. illustration)
Alternatively, it might be a claw, for instance from an Iguanodon.
Other opinions definitely needed!...
(you there, Thomas?)
Thanks for your info - I did a bit of looking at some of the other forum questions and wondered if it could possibly be a pre ice age bull horn core? Any ideas?
I would of course love for it to be something a bit more interesting, but clearly have no idea or expertise in this field. It's great to be sharing it on here!
any help is much appreciated.
Hi Steve, your research has served you well. This is a horn core, the bone part of the skull which sits inside the keratinous sheath of the horn in cattle. Aging is much more difficult, it is not the sort of size where I would immediately suggest Auroch, infact it could just be a large sheep.
When decomposition takes place in an oxygen depleated environment there is incomplete oxidation of carbon and this leaves a black staining. The commonest oxygen depleated environment being underwater.
