The origins of South America's exceptional plant diversity are poorly known from the fossil record. [...] Key Result At LH, from 4,303 identified specimens, we recognize 186 species of plant organs and 152 species of leaves. Adjusted for sample size, the LH flora is more diverse than comparable Eocene floras known from other continents. The RP flora shares several taxa with LH and appears to be as rich, although sampling is preliminary. The two floras were previously considered coeval.Expand
Richness of plant-insect associations in Eocene Patagonia: a legacy for South American biodiversity.
TLDR
Significant more damage diversity is found at Laguna del Hunco than in the North American floras, whether measured on bulk collections or on individual plant species, for both damage morphotypes and feeding groups. Expand
Early Eocene Spore and Pollen Assemblages from the Laguna del Hunco Fossil Lake Beds, Patagonia, Argentina
TLDR
The LH spore-pollen assemblages augment the plant fossil record for this significant Eocene locality by incorporating new taxa, and reinforce the presence of plant families previously reported from macrofossils, such as Juglandaceae, with pollen grains similar to those of the Engelhardia-Alfaroa group. Expand
Papuacedrus (Cupressaceae) in Eocene Patagonia: A new fossil link to Australasian rainforests.
TLDR
Combined evidence indicates a biome similar to extant subtropical, or tropical montane, rainforests that persisted for at least 4.4 Myr, linking elevated floral richness to abundant rainfall. Expand

TLDR
Dacrycarpus puertae provides the first significant Asian link for Eocene Patagonian floras, strengthens the biogeographic connections from Patagonia to Australasia across Antarctica during the warm Eocene, and indicates high-rainfall paleoenvironments. Expand
Resolving Australian analogs for an Eocene Patagonian paleorainforest using leaf size and floristics.
TLDR
The legacy of LH is evident not only in subtropical and tropical Australia but also in tropical montane Australasia and Southeast Asia, reflecting the disparate histories of surviving Gondwanan lineages. Expand
A Paleocene lowland macroflora from Patagonia reveals significantly greater richness than North American analogs
Few South American macrofloras of Paleocene age are known, and this limits our knowledge of diversity and composition between the end-Cretaceous event and the Eocene appearance of high floralExpand

Casuarinaceae from the Eocene of Patagonia, Argentina
TLDR
The diverse Gymnostoma described here further strengthens biogeographic links between Paleogene floras of Patagonia and Australasia and the view that the family was diverse and had widespread distribution during the early Eocene climatic optimum. Expand

High Plant Diversity in Eocene South America: Evidence from Patagonia
TLDR
Radioisotopic and paleomagnetic analyses indicate that the flora was deposited 52 million years ago, the time of the early Eocene climatic optimum, when tropical plant taxa and warm, equable climates reached middle latitudes of both hemispheres. Expand
The Monimiaceae and a New Laurelia
TLDR
The family Monimiaceae does not reach the North Temperate zone, consequently it is unfamiliar to students of fossil floras who have largely lived in that zone, and it seems likely that it may be represented in the Eocene floras of southeastern North America. Expand

TLDR
It is indicated that evidence of neotropical rainforest is exceedingly rare and equivocal before the Palaeocene, and a mismatch of evidence regarding the age of origin between sites of palaeobotanical high diversity and sites of predicted tropical climates should be reconciled with intensified collecting efforts in South America.
