Abstract
Se informa de la presencia de 21 órgano-especies nuevas para la tafoflora de península Fildes, isla Rey Jorge (Antártica); 19 de ellas corresponden a hojas o pinnas y 2 a frutos. Un género y una especie son descritos como entidades nuevas para la ciencia: Sapindocarpon y S. covacevichii, respectivamente. Sobre la base de esta nueva información se discute la edad de los sedimientos portadores, concluyéndose que corresponden al (¿Paleoceno superior?) ,- Eoceno inferior. Asimismo, se discute el carácter de la flora fósil, confirmándose que ésta corresponde al tipo conocido como paleoflora mixta.
Twenty-one organ-species not recorded before in the fossil flora of Fildes Peninsula, King George Island (Antarctica), are here reported, 19 of them consist of leaves or pinnae remains and two of them of fruit remains. One organ-genus and one organ species are described as new entities for science: Sapindocarpon, and S. covacevichii. Based on this new information, the age of the fossiliferous beds is discussed, a (latter Palaeocene?) lower Eocene age is proposed for it. The characterization of the flora is also discussed, a "mixed palaeoflora" type is inferred to confirm other author's views.
