This fossil (at least I presume its a fossil) was given to me by a Somali friend on a trip to Somaliland (Northern Somalia).
I'm an anthropologist by training and have absolutely no idea where to start finding out what it is but I'm really intrigued. If anyone can help me to shed some light I'd be really grateful.
I terms of size I would say its around 7/8cm in length and 5/6cm in diameter.
Thanks for the help.
Is it a spiral (I think so, but it could be separate rings, going just on the photo)?
Please could we have a photo from each end as well.
It would be useful to know its density, as a means of determining whether it is made of rock (ie. a fossil) or not. You can determine its volume by water displacement, weight on kitchen scales, preferably ending up with density in g/ml (=g/cc).
Any details on location would also be useful (Northern Somalia being quite large).
I should have included some more detailed pictures to begin with.
Yes it is a spiral...
Using my humble student kitchen equipment I have come to the reckoning that it has a volume of around 130cc and weighs 210g so a density of 1.62 (g/cc).
I believe that it was found on a hike to the rock paintings of Las Geel (the rock painting site outside of Hargeisa.)
For some strange reason it wont allow me to upload pictures to this post so I will start a new thread with the same title.
