Text-fig. 7B. Eospondylus primigenius (STÜRTZ) Bundenbach, Eschenbach-Bocksberg quarry, Lower Devonian, Lower Emsian (Zlichovian), Hunsrück Slate, BMNH E3358, x 4. Hunsrück Slate articulated specimen. Underside of arm showing two contrasting appearances of lateral arm plates in a single arm. The arm is rolled slightly. Of the left lateral arm plates the lateral surface is extensively exposed. The spine ridge faces distally (posteriorly).

The canal for radial water vessel is in center of zygosphene knob and zygotreme pit, like spout and funnel. At distal outer edges of vertebrae is cupola for tube feet. There are no under arm plates. in Isolated Ossicles Of The Family Eospondylidae Spencer Wright, 1966, In The Lower Devonian Of Bohemia (Czech Republic) And Correction Of The Systematic Position Of Eospondylid Brittlestars (Echinodermata: Ophiuroidea: Oegophiurida)

Text-fig. 2. Eospondylus primigenius (STÜRTZ) Bundenbach, Eschenbach-Bocksberg quarry, Lower Devonian, Lower Emsian (Zlichovian), Hunsrück Slate,, NM S 4764, x 3. Specimen with ventral arm coiling. The specimen is on its dorsum in slate with all five rays curled ventrally inward toward mouth area on underside of disk. Barely visible are tips of two jaws; slightly exposed are proximal parts of rays in oral view extending outward from disk. The location of abrupt ventral bending of rays is indicated by emergence from slate of five rays in aboral view that point inward toward buried disk. Based on ventral bending of rays and intimate association with crinoids Eospondylus has been interpreted as stratigraphic first occurrence of Order Euryalida, which contains epizoic gorgonocephalid and euryalid basket-stars of modern oceans. This status is rejected using new evidence from isolated vertebrae.

Figure. Constrained ordination plot as produced from canonical correspondence analysis (CCA). The variability of environmental variables is summarized on Axis 1 and Axis 2 of the constrained biplot, explaining the variability of the trophic groups included in the red fox's diet. Trophic groups are shown with black line (unfilled) pyramids, whereas environmental variables are shown with black filled pyramids. Proximity and distance of response centroids to predictor centroids indicate positive and negative correlations between them, respectively. in Factors affecting the diet of the red fox (Vulpes vulpes) in a heterogeneous Mediterranean landscape

Figure 2. The relationship between relative gut length and trophic position for the 6 freshwater fish species. (a) Relative gut length is presented in percent of body length; (b) Relative gut length is presented in percent of total length. Averaged values of trophic position (TP) from the study by Zhang et al. (2013). Grey and black circle dots correspond to TP for stable isotope analysis (SIA) and for gut content analysis (GCA), respectively. Dashed line represents the linear fitting of relative gut length and TP for SIA, while solid line represents the linear fitting of relative gut length and TP for GCA.
