Condylactis gigantea fluourescing on rocks. The anemones are in a tank illuminated by ultraviolet (black) light. The anemones absorb the invisible ultraviolet light and reflect it back as visible bright green light.

Tree ring dating
Tamarisk stem cross-section cut 2.8 m below the ground surface showing how sediment deposition is dated using tree rings. Following initial burial of 68 cm in 1969, ring-width decreased, vessel size increased, and annual transitions became less distinct. After a second burial by 41 cm in 1972, annual transitions became indistinguishable.
