Found in hills coastal west Wales. Looks like a huge almond. Weighs 2kg. Notice £1 coin on slated bench for scale.
Superficially, it looks like a concretion.
But its surface texture is intriguing, likewise its symmetry (though concretions are often symmetrical).
Please tell ue more about it:
- the location more precisely (town, bay, grid ref, etc.)
- its density (numerically would be great, but a general impression would be useful - ie. heavy or light for its size, compared with normal rock or concrete)
- is a magnet (including a compass needle) attracted to it?
- is a non-magnetized steel or iron object (eg. a pin or kitchen knife) attracted to it?
- anything about where you found it (loose on the beach or in the rock face, what fossils or minerals were nearby, any industrial workings nearby, etc.)
- was there just this one, or were these some/many others?
