Echinoderms, Crinoids, OrdovicianAbstract
The revision of the echinoderms from Collado de Tosas, based on the original specimens and additional material, is undertaken. The study shows that the initial attribution to the genus Trochocystites belonging to the Homalozoa Cincta has been induced by the tectonic deformation and the presence of recristallization lamellae in the natural molds. New observations allow to conclude without ambiguity that these skeletal elements are isolated columnals with a broad lumen, of crinoids. The presence of Cambrian in the section, established exclusively on the initial determinations, cannot longer be maintained.
