M a t e r i a l. Oriolo MSF 657, 659, 689.

D e s c r i p t i o n. Leaf, simple, petiolate, petiole 6–10 mm, lamina 60–80 mm long, 30–35 mm wide, ovate to elliptic, shallowly to deeply lobed, base acute-rounded, cordate, apex acute, lamina shallowly lobed, lobes with pointed apical tip (MSF 657), lamina irregular, deeply lobed, lobes pointed-triangular elongated (MSF 689), lamina deeply lobed, lobes with secondary lobes (MSF 659), number of lobes 5–8.

R e m a r k s. The leaf morphological variability in the specimens from Oriolo fits well with the modern variability encountered in Q. cerris and in fossils from other Pleistocene localities from the Submediterranean region ( Denk et al. 2021). Deeply lobed leaves with secondary lobes are also found in Q. pubescens , but they normally have fewer lobes ( Schwarz 1937).
