| 1978 | Incremental growth layers in the dentine of dugong incisors (Dugong dugon (Müller)) and their application to age determination. Zool. Jour. Linn. Soc. 62: 317-348. 10 figs. 2 pls. Apr. 1978. –Concludes from a study of Australian dugong tusks that sexual maturity is reached at about 10 growth layers (= 5 or 10 years of age) and that the life span is just under either 30 or 60 years. Tooth succession in the upper jaw is correlated with number of growth layers in the tusks. | ||
