These dark patches on the limestone are ancient animal (shrimp-like creatures, we think!) burrows, made when this was a muddy sea floor. It is believed that a storm washed the the animals from these burrows and filled them in with gravel or sand (in this case Crinoid segments).

What a great list of advice. Breithlá Sona duit, a Dharach!
Today is my birthday. 48. Is that old? Well, it's the oldest I've ever been.
Have I learnt anything worth sharing in that time? Let's see.
