EXAMPLE

It is not the scope of this paper to present and analyze large sets of morphometric data, but an example that can be obtained with AMOR shall be given. Globorotalia menardii (Figure 14) is an extant, Neogene tropical planktonic foraminifer, which shows considerable morphological variation biogeographically and since the upper Miocene (Kappertsbusch 2007). Figure 17 and Figure 18 illustrate contoured bivariate frequency diagrams of spiral height versus axial length measurements of Holocene representatives of G. menardii from two surface sediment samples in the Atlantic Ocean. The images for these measurements were generated using the auto-measurement mode of AMOR: the outline extraction and analysis of morphometric data were obtained using the methods described in Knappertsbusch (2007).
