Extract

Of the 50 thousand or more species descriptions that exist in my reference library, there is very little change over 130 years in the basic vocabulary used to describe the shape or the ornament of the ostracode valves. Although there have been some modifications (Sylvester-Bradley and Benson, 1971) following the availability of the SEM, arguably the most important change in ostracodology will come when we are able to describe the outside form of the carapace in functional terms, as we do the inside. It is here where the future of learning about their adaptive history lies (Benson, 1974, 1975, 1981, 1983).
