Resumen:
We identified sixfossil-species of angiosperms based on fossil woods from two small collectionsfrom the Beta Member (lower Campanian) of the Santa Marta Formation on JamesRoss Island: 1) a new species of Paraphyllanthoxylon (Angiospermincertae sedis) which represents the first Antarctic record of that fossil-genus;three previously known Antarctic fossil-species, but from new localities, 2) Laurelitesjamesrossii (Laurales), 3) Hedycaryoxylon tambourissoides(Monimiaceae) and 4) Eucryphiaceoxylon eucryphioides (Cunoniaceae); 5) anew species of Weinmannioxylon (Cunoniaceae); 6) a new fossil-genus andfossil-species with uncertain affinity, but with similar wood anatomy andvessel-ray parenchyma pits to the Santalales and Malpighiales. The richness ofangiosperm woody species is increased for the Late Cretaceous of Antarctica.The fossil woods are used to interpret ancient forests composition and to makesome climatic inferences during the Campanian of the Antarctic Peninsula.
