Sorry for the negativity HD but they look natural to me , probably solution holes . There is some info here http://mc2.vicnet.net.au/home/aura/shared_files/Cupules.pdf (about p 10 ) describing some natural cups .We should really compile some pics to illustrate this stuff .
No apology necessary! I only sought clarity! Thanks very much for the prompt response and the reading material! Certainly some food for thought in that mighty PDF. Thank you tiompan.If you are in the D&G area (Lanarkshire is a bit of an RA desert ) it might be an idea to contrast and compare some of the local cups . The inverted cone description whilst rough is useful i.e lack of sharp edges going straight into the rock rather than at an angle etc .
