Abstract
This is the first report of a fossil flora from Hannah Point, Livingston Island, South Shetland Islands,
Antarctica. The fossiliferous content of an outcrop, located between two igneous rock units of Cretaceous age are
mainly composed of leaf imprints and some fossil trunks. The leaf assemblage consists of 18 taxa of Pteridophyta,
Pinophyta and one angiosperm. The plant assemblage can be compared to other Early Cretaceous floras from the South
Shetland Islands, but several taxa have an evidently Late Cretaceous affinity. A Coniacian-Santonian age is the most
probable age for the outcrops, supported by previous K/Ar isotopic studies of the basalts over and underlying the
fossiliferous sequence
