Stratigraphy
Stratigraphy comments: Dominici et al. (2018) divided the whole Pliocene marine succession of Tuscany into six synthems (S1 to S6) and referred Orcinus citoniensis to a broad stratigraphical interval (S3 to S6) accounting for the whole Piacenzian (3.6-2.59 Ma). However, alternative chronostratigraphic assessments of the siliciclastic deposits exposed in the vicinities of Cetona place these sediments within the Zanclean (Nalin et al., 2016, fig. 2). Unfortunately, no biostratigraphically significant microfossils were found by examining a sample of the sediment that entombs the fossil (S.C. Vaiani, pers. comm.). All things considered, the O. citoniensis holotype is referred herein to a generic Pliocene epoch.
