This palm-sized rock is from the beach at Eccles-on-Sea (North Sea coastline).
I can see four types of material:
- A brown, slightly translucent, 6cm tubular fossil(?) that I can mark with a steel blade;
- Coarse, light material--stained reddish-brown in places--that I can scratch away with a fingernail;
- Hard, dimpled, dark-brown material that I can't scratch (iron perhaps?); and
- Shiny black stone that I can't scratch.
I'm mostly interested in the fossil--if it is a fossil. Thank you. :-)
