This is a close view of the limestones to show the structure at this locality, a disused quarry.
- The surface is very smooth, because the rock has been quarried using wire cutting. This technique has been discontinued in many places because it is potentially very dangerous.
- How would you describe the shapes of the beds?
- In fact, each 'bed' is a colony of carbonate-secreting organisms. Most are stromatoporoids (a type of sponge), whilst the lighter-coloured colony in the centre is a tabulate coral.
