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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
