Elliptic endocarps preserved as impressions are assignable to Nyssa disseminata ( LUDWIG ) KIRCHHEIMER because the length is less than 20 mm and there is a broad dehiscence valve covering the majority of the stone’s width. This species is common in a few Pliocene sites in Italy ( Martinetto 1995 , Forno et al. 2015 ), but is here recorded for the first time in Miocene sediments. M a t e r i a l. Endocarps (Monte Tondo MSF1830, MSF1831).
