摘要

:报道了南极半岛东部Vega岛晚白垩世沉积物中Nothofagaceae化石叶片及其相关的孢粉植物群。在这两个单位沉积时，树叶的形态支持一个可能的近岸环境。花粉和孢子证据表明，该地区为针叶林和被子植物混交林，以足足科和石松科为主，林下有蕨类、石松类和苔藓类。这片森林是在坎帕尼亚-马斯特里赫特中部温带和潮湿的条件下发展起来的。在两种化合物中各保存了下来。在不规则的，相对的/次要的，

Nothofagus and the associated palynoflora from the Late Cretaceous of Vega Island, Antarctic Peninsula

: Nothofagaceae fossil leaves and an associated palynoflora from Late Cretaceous sediments of Vega Island, eastern Antarctic Peninsula, are presented. The leaves palynomorphs supports a probable nearshore environment at time of deposition for both units. Pollen and spore evidence suggests a mixed conifer and angiosperm forest, with Podocarpaceae and Nothofagus as the main components, and ferns, lycopods, and mosses in the understory. This forest developed under temperate and moist conditions during the middle Campanian-Maastrichtian. in the in two compound each preserved. on the irregular, opposite/ secondaries,
