Ornamental and shape variation in Hemicytherura fulva McKenzie, Reyment and Reyment (Ostracoda; Eocene, Australia).


Hemicytherura fulva displays ornamental variation of two kinds. One of these (termed the morph LACE) is vaguely linked to shape and is generally dilferently distributed from the rest of the material; this morph may possess intrinsic evolutionary significance. The other categories are probably ecophenotypic in nature. Methods of distance based multivariate morphometry and geometric morphometry were used for the shape study.

Palabras clave
