Ichnogenus: Evazoum NICOSIA & LOI, 2003
Etymology: In honor of Miss Eva Sacchi, Ph.D. sudent, member of the ichnological
crew, and skilled artist who helped to refine the drawings, joind to the suffix "zoum" (=
beast); the whole recalls the sound of the beautiful, prosauropod-ascribed
ichnotaxon Otozoum.

Ilario passed away suddenly in the winter of 2003.
