“…For example, several sites on the Antarctica Peninsula and other landmasses within or bordering the Antarctic Circle preserve closely spaced in situ stumps or transported wood on sites that were influenced by fluvial, volcanic and other disturbances (e.g. Pole 1994, Francis 2000, Thorn 2005, Olivero 2012, Iglesias 2016, Kvaček & Vodrážka 2018). Similarly, interpretations of canopy shape based on NLRs of the palaeoconifers is conjectural.…”

“…Nothofagus sp. described by Kvaček and Vodrážka (2016: fig. 7K), from the Coniacian Hidden Lake Fm, James Ross Island, EAP, is a small leaf fragment with simple dentate/crenate margin, craspedodromous venation and percurrent tertiary veins.…”

“…1 and Morphotype LDB 1). The characters of the Hidden Lake leaf observed by Kvaček and Vodrážka (2016) The specimens studied by Hayes et al (2006) are described as "morphotypes with architectural characteristics typical of the Cunoniaceae and Nothofagaceae", and unfortunately there are no photos of the specimens. The line drawings show only gross leaf morphology of primary and secondary veins, therefore it was impossible to establish informative comparisons with the herein described material.…”

“…Nothofagus species are usually dominants in the temperate forests where they grow (e.g., Glade-Vargas et al 2018). Their fossil record is extremely abundant and consists of leaves, wood, reproductive structures, and pollen grains, in the areas mentioned above, as well as in the Antarctic Peninsula (e.g., Dettmann and Thomson 1987;Dutra and Batten 2000;Hayes et al 2006;Poole and Cantrill 2006;Kvaček and Vodrážka 2016;Cantrill 2018).…”

Nothofagaceae fossil leaves and an associated palynoflora from Late Cretaceous sediments of Vega Island, eastern Antarctic Peninsula, are presented. The leaves are described as Nothofagus sp. 1 and Morphotype LDB 1, and come from the Snow Hill Island (late Campanian-early Maastrichtian) and the López de Bertodano (late Maastrichtian) formations, respectively. The palynoflora obtained from levels immediately above and below the Nothofagus sp. 1 and in the same horizon as the Morphotype LDB 1, included terrestrial and marine elements. In the palynoflora associated with Nothofagus sp. 1, conifers are dominant and pollen grains with Nothofagus affinity are represented by four species: Nothofagidites kaitangataensis (Te Punga) Romero 1973 and Nothofagidites senectus Dettmann and Playford 1968, which belong to the ancestral pollen type, as well as Nothofagidites dorotensis Romero 1973 and Nothofagidites sp. of the brassii-type. Cryptogamic spores, marine dinoflagellate cysts and algae, among others, are part of the assemblage. The palynoflora associated with the Morphotype LDB 1 also contains abundant conifer and angiosperm pollen grains with N. dorotensis as the only Nothofagus species recorded. Marine dinoflagellate cysts are scarce while fungi and phytodebris are common elements. The joint presence of marine and non-marine 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.
