Abstract
A specimen of the dalmanitacean trilobite Rhenops sp. cf. R. anserinus with ventral appendages is described and discussed. It is shown to have 1 pair of antennae, 4 pairs of cephalic legs, 11 pairs of thoracic legs, and 9(?) pairs of pygidial legs. The pygidial legs differ clearly from those of the thorax in their construction and are also smaller and more closely spaced. Of the outer appendage branch a few sets of lamellar spines are visible. D Trilobita, appendages, segmentation. Vom dalmanitiden Trilobiten Rhenops sp. cf. R. anserinus wird ein Exemplar mit ventralen Extremitaten beschrieben und diskutiert. Es hat 1 Antennenpaar, 4 Kopfbeinpaare, 11 Thorakalbeinpaare, und 9(?) Pygidium-Beinpaare. Die Pygidium-Beinpaare unterscheiden sich in ihrer Konstruktion klar von den Thorakalbeinpaaren. Sie sind kiirzer, und der Abstand zueinander ist schmaler. Lamellendornen (sogen-annte ‘Kiemenanhange’) sind an einigen wenigen Aussenasten sichtbar.This publication has 7 references indexed in Scilit:
