Resumen:
Abstract. In the southeastern corner of the Isla Grande of Tierra del Fuego, southernmost Argentina, small
outcrops representing Late Eocene-Early Oligocene sedimentation in fluvial environments, are referred to
the Sloggett Formation. This unit crops out along the shores of Bahía Sloggett, where it is represented by
carbonaceous mudstones, sandstones and conglomerates. A new paleofloristic collection of this site, originally
reported by Andersson at the beginning of the 20th, was collected and analyzed, revealing the presence
of gymnosperm and angiosperm leaves. Conifers are represented by probable Podocarpaceae and
the presence of Araucariaceae is confirmed by leaves with preserved anatomy. Angiosperms, although
fragmentary, have been grouped in morphotypes, which are referred to the Nothofagaceae, Myrtaceae
and Lauraceae. The Sloggett paleoflora is similar in composition to other contemporary floras, described
from southern South America and that originated in temperate to cold-temperate and humid forest.In the southeastern corner of the Isla Grande of Tierra del Fuego, southernmost Argentina, small
