Title: Unusual S0 galaxies in the Virgo Cluster Authors: S.N. Kemp, C.L. Martinez-Robles, R.A. Marquez-Lugo, D. Zepeda-Garcia We present new photometric and morphological results on some unusual lenticular galaxies in the Virgo cluster. NGC 4620, a dwarf S0, is seen to have a faint, fossil-like spiral arm structure implying stripping processes have affected a previous dwarf spiral galaxy. NGC 4888 appears to be a face-on barred galaxy with faint spiral arms at each end of the bar, although it possibly could represent an edge-on warped disk galaxy. Finally the E-S0 galaxy NGC 4660 has a previously unidentified long curved filament.
