First Evidence for Wollemi Pine-type Pollen (Dilwynites: Araucariaceae) in South America

  author={Michael K. Macphail and Raymond Carpenter and Ari Iglesias and Peter Wilf},
  journal={PLoS ONE},
We report the first fossil pollen from South America of the lineage that includes the recently discovered, extremely rare Australian Wollemi Pine, Wollemia nobilis (Araucariaceae). The grains are from the late Paleocene to early middle Eocene Ligorio Márquez Formation of Santa Cruz, Patagonia, Argentina, and are assigned to Dilwynites, the fossil pollen type that closely resembles the pollen of modern Wollemia and some species of its Australasian sister genus, Agathis. Dilwynites was formerly… Expand
First South American Agathis (Araucariaceae), Eocene of Patagonia.
PREMISE OF THE STUDY Agathis is an iconic genus of large, ecologically important, and economically valuable conifers that range over lowland to upper montane rainforests from New Zealand to Sumatra.Expand
Agathis trees of Patagonia's Cretaceous-Paleogene death landscapes and their evolutionary significance.
A Mesozoic divergence for the Araucariaceae crown group, previously challenged by molecular divergence estimates, is supported by the combined phylogenetic analyses including the fossil taxa. Expand
Early Cenozoic Vegetation in Patagonia: New Insights from Organically Preserved Plant Fossils (Ligorio Márquez Formation, Argentina)
New collections of Argentine LMF mudstones are presented, thus far unique in the Patagonian region in containing organically preserved plant fossils, including leaves with cuticular preservation, providing further evidence for warm and humid climates in Patagonia during the early Paleogene and for a strongly Gondwanic flora.

Early Eocene Spore and Pollen Assemblages from the Laguna del Hunco Fossil Lake Beds, Patagonia, Argentina
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.

New potential nearest living relatives for Araucariaceae producing fossil Wollemi Pine-type pollen (Dilwynites granulatus W.K. Harris, 1965)
Two Agathis species that are endemic to New Caledonia, A. moorei and A. ovata, are potential nearest living relatives of the fossil species Dilwynites granulatus, whose stratigraphic distribution has been used to establish a fossil record for Wollemia. Expand
A new megaflora (leaves and reproductive structures) from the Huancané Formation (Lower Cretaceous), Peru
Abstract We describe fossil leaves and reproductive structures remains from the Lower Cretaceous of Peru. A great part of the plant fossils are very well preserved, and they come from three differentExpand
The Cenozoic history of New Zealand temperate rainforests: comparisons with southern Australia and South America
ABSTRACT The temperate rainforests of southern hemisphere continents share Gondwanan antecedents, but subsequent trajectories exhibit divergent patterns. We review the Cenozoic history of majorExpand
The Gondwanan heritage of the Eocene–Miocene Patagonian floras
Abstract The breakup of Gondwana and the associated climatic changes led to the fragmentation of floras that were once connected across the Southern lands. The diversity of the Gondwanan remnants hasExpand
Paleo-Antarctic rainforest into the modern Old World tropics: the rich past and threatened future of the "southern wet forest survivors".
Understanding how and where lineages from ancient Gondwanan assemblages co-occur today has implications for the conservation of global rainforest vegetation, including in the Old World tropics. Expand
Macroevolutionary dynamics in the early diversification of Asteraceae.
Diversification rates increased gradually from the origin of Asteraceae approximately 69.5Ma in the late Cretaceous through the Early Eocene Climatic Optimum at least, and significant rate shifts were not strongly correlated with intercontinental dispersals or polyploidization. Expand


Araucariaceae macrofossil record from South America and Antarctica
Araucariaceae fossils are abundant in Patagonia and on Seymour (Marambio) and King George (25 de Mayo) islands, Antarctica. Araucariacean macrofossil suites are represented by records of 121 woods,Expand
Papuacedrus (Cupressaceae) in Eocene Patagonia: A new fossil link to Australasian rainforests.
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
