Libby later received the Nobel Prize in Chemistry in 1960: (From Taylor, 1987).

Growth banding is produced by varying orientations of crystal fan bundles towards the image plane.

Growth rates of the Mg-calcitic internodal increments were investigated by the counting of colour bands and radiocarbon dating.

Hence, the isidid skeleton provides a high-resolution archive of paleoceanographic dynamics in deeper water masses.

There are three principal isotopes of carbon which occur naturally - C12, C13 (both stable) and C14 (unstable or radioactive).

The data provide a maximum age of 3,975 /- 35 years BP, and a record spanning 240 /- 35 years.

While calculated longitudinal growth rates amount to an average of 5 mm/year during a 55-year record, average lateral linear extension rates of 0.4 mm/year are an order of magnitude lower, still allowing for a seasonal to annual resolutionof colour bands on a macroscopic scale and for a daily to monthly resolution on microscales of individual crystal generations to fascicle bundles.

Nyerup's words illustrate poignantly the critical power and importance of dating; to order time.
