mooky Posted August 17, 2006 Share Posted August 17, 2006 Yesterday I spent the day on the Ile d ré. I went a walk (in the pouring rain) on the beach to see if I could find a pebble with a hole in it. To my amazement there where hundreds.The stones seem to be sandstone/limestone very soft with very deliberately made holes in them . Obviously some creature, anyone any idea please. I love 'holey' pebbles, never have I seen so many in one place.Thank you Link to comment Share on other sites More sharing options...
Cassis Posted August 17, 2006 Share Posted August 17, 2006 Is it not just natural wear and weathering in the softest part of the pebble? I can't imagine why any creature would want to pick a hole in a pebble. [8-)] Link to comment Share on other sites More sharing options...
mooky Posted August 17, 2006 Author Share Posted August 17, 2006 I dont think it is just natural weathering. Some stones have many holes in. Link to comment Share on other sites More sharing options...
chris pp Posted August 17, 2006 Share Posted August 17, 2006 I thought it was where softer fossilised material had washed away over millions of years as the rocks broke up and were washed around by the tides.Chris Link to comment Share on other sites More sharing options...
Deimos Posted August 17, 2006 Share Posted August 17, 2006 There is a mollusc that creates holes in rocks. Cannot remember its name and thought is was in rocks rather than stones. The holes it makes are of a fairly specific size (which I cannot remember) - but that would be a give away. Some time I will look it up but a bit busy now.Ian Link to comment Share on other sites More sharing options...
mooky Posted August 18, 2006 Author Share Posted August 18, 2006 I had done a bit of research and think it maybe pholas dactylus which bores holes in marly limestone. I need to find out what the stone is on the Il .I think this is a possibility. Link to comment Share on other sites More sharing options...
