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.

There were others ,possibly more appropriate and with better pics , but I can't find the url's .
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 .
