Moorlog & Doggerland
Spotting the fragment above, I thought grizzled shoe-sole before I saw moorlog. Dusted with salt crystals, the peat was pierced with finger-sized holes, that I recognised – with glee – were made by piddocks. Usually, these elegant marine bivalves live embedded in soft seabed rock such as chalk or slate. Yet here they'd burrowed into an ancient fen beneath the sea.
