Text-fig. 1. Eospondylus primigenius (STÜRTZ) Bundenbach, Eschenbach-Bocksberg quarry, Lower Devonian, Lower Emsian (Zlichovian), Hunsrück Slate, specimens PWL 1996 57LS (NMM) top image (A) x 1.5, and PWL 1996 66LS (NMM) bottom image (B) x 1.7. Specimen with rays bent into strong curves. Such flexibility and attitudes of rays differentiate the behavioral ecology of Eospondylus from all other Hunsrück Slate ophiuroids. Delicateness of the top specimen and robustness of the bottom specimen is perhaps the combined result of real phenotypic differences, differences of preserved detail, and differences of distortion of the rock.

Figure 3 - Relative abundance proportions of Asteroidea (AST), Ophiuroidea (OPH) and Holothuroidea (HOL) within the three assemblages (Eastern Shelf, Southern Shelf, and Overdeepened Basins I & II) defined by cluster analysis and multidimensional scaling. In addition, the two most abundant families are given for each echinoderm class.

Figure 2 - Faunal resemblance pattern (a) and geographic distibution (b) of stations where both asterozoans and holothurians were sampled during "Polarstern" cruises PS01, PS04, and PS06. a Multidimensional Scaling (MDS) plot showing the faunal between-station resemblance pattern. The numbers are station numbers, the affiliation of stations to asterozoan-holothurian assemblages, based on cluster analysis (complete linkage, threshold of 21% Bray-Curtis similarity), are indicated by color codes. According to cluster analysis, stn 213 belongs to cluster "Overdeepened Basins II" but based on MSD ordination it was assigned to cluster "Eastern Shelf" b Geographic map of stations. Symbol color denotes assemblage affiliation according to cluster analysis and Multidimensional Scaling (see Fig. 2a), symbol size is scaled according to the number of species at each station (ranging from 13 to 51).

Figure 1 - Map of stations in the southeastern Weddell Sea (Southern Ocean) where either asterozoans and holothurians separately or both asterozoans and holothurians together were sampled during "Polarstern" cruises PS01, PS04, and PS06. In case of station number 310 that occurred during two cruises, cruise numbers are included in the station labels.
