TLDR
Antarctic vegetation is today mostly restricted to non-vascular plants, with a few small angiosperms clinging to the Antarctic Peninsula However, probably as recently as the mid-Late Pliocene woody angiospms were present in inland Antarctica, suggesting an overall presence of complex and diverse vegetation as mentioned in this paper.About:

The breakup history of Gondwana and its impact on pre-Cenozoic floristic provincialism
TL;DR: The broad succession of pre-angiosperm floras is documents, the distinctive elements of the Early Cretaceous Gondwanan floras immediately preceding the appearance of angiosperms are highlighted and it is suggested that latitudinal controls strongly influenced the composition of GONDwananFloras through time even in the absence of marine barriers between Gondwana and the northern continents.

The Antarctic Region: Geological Evolution and Processes
TL;DR: The Antarctic Region: Geological Evolution and Processes is a collection of the Proceedings of the VII International Symposium on Antarctic Earth Sciences, held in Siena, Italy, in 1995 and sponsored by SCAR as discussed by the authors.

Ecological aspects of the Cretaceous flowering plant radiation
Scott L. Wing,Lisa D. Boucher +1 more
TL;DR: Morphology of leaves, seeds, and wood is consistent with the status of most Cretaceous angiosperms as herbs to small trees with early successional strategy, and analyses of sedimentary environments indicate that angios perms not only originated in unstable habitats but remained centered there through most of theCretaceous.

Did dinosaurs invent flowers? Dinosaur–angiosperm coevolution revisited
TL;DR: It is concluded that there are no strong spatiotemporal correlations in support of the hypothesis that dinosaurs were causative agents in the origin of angiosperms; however, dinosaur–angiosperm interactions in the Late Cretaceous may have resulted in some coevolutionary interactions, although direct evidence of such interactions is scanty at present.

Biogeography and diversification of colletid bees (Hymenoptera: Colletidae): emerging patterns from the southern end of the world
TL;DR: This paper aims to study the temporal and spatial diversification of colletid bees to better understand the processes that have resulted in the present southern disjunctions.

Paleotemperature history of the Cenozoic and the initiation of Antarctic glaciation : Oxygen and carbon isotope analyses in DSDP Sites 277,279, and 281
TL;DR: An oxygen and carbon isotopic history based on analyses of benthonic and planktonic foraminifera in three overlapping subantarctic sections is presented for the last 55 m.y. as mentioned in this paper.
Journal ArticleDOI
Fossil pollen records of extant angiosperms.
TL;DR: The fossil record for angiosperm pollen types which are comparable to recent taxa is evaluated, following a similar survey published in 1970, with special attention paid to the dating of the sediments.

The opening of Drake Passage
Peter F. Barker,J. Burrell +1 more
TL;DR: In this article, the authors used magnetic anomalies to deduce the history of the opening of Drake Passage, the deep-water channel between South America and West Antarctica, and concluded that the Antarctic Circumpolar current started at 23.5 ± 2.5 Ma, a time indistinguishable from the Oligocene-Miocene boundary.

Review of seafloor spreading around Australia. I. synthesis of the patterns of spreading
TL;DR: Veevers et al. as discussed by the authors reconstructed the seafloor around Australia that spread during the dispersal of Argo Land, India, Antarctica, Lord Howe Rise/New Zealand and the Papuan Peninsula and determined the pattern of spreading around Australia was determined by two longstanding (earlier Phanerozoic) factors that operated in a counterclockwise direction: (1) penetration from the northwest by the Tethyan divergent ridge; and (2) rotation from the northeast of the Pacific convergent arc and back-arc.
