Two new species of cyrtocrinid crinoids, Crataegocrinus zignoi n.sp. and Psalidocrinus dalpiazi n.sp., are described from the Tithonian of North-East Italy. Up today, the genus Crataegocrinus Manni & Nicosia, 1985 was monotypic and therefore C. zignoi n.sp. represents the second species and it permits a more correct phylogenetic interpretation of the genus.

Abstract

Two new species of cyrtocrinid crinoids, Crataegocrinus zignoi n.sp. and Psalidocrinus dalpiazi n.sp., are described from the Tithonian of North-East Italy. Up today, the genus Crataegocrinus Manni & Nicosia, 1985 was monotypic and therefore C. zignoi n.sp. represents the second species and it permits a more correct phylogenetic interpretation of the genus. Besides it was made the revision of the family Psalidocrinidae Zitt, 1978 to ascribe Crataegocrinus to this family.
