Distribution of the eight lenticular galaxies within the phase-space diagram traced by galaxies within the Virgo cluster. Grey dots indicate the Virgo cluster galaxies with a recessional velocity < 3500 km s⁻¹ extracted from the sample of Boselli et al. (2014a). The solid lines delimit the different regions extracted from the simulations of Rhee et al. (2017) to identify galaxies in different phases of their infall into the cluster: First (not yet fallen), recent (0 < τ_inf < 3.6 Gyr), intermediate (3.6 < τ_inf < 6.5 Gyr), and ancient (6.5 < τ_inf < 13.7 Gyr) infallers.
