A new genus and species, Wairarapaia mildenhallii Cantrill et Raine, is established for two ovulate cones with helically inserted cone‐scale complexes and a centrally positioned inverted ovule from the Cretaceous (late Albian to Cenomanian) of New Zealand. The cones are up to 60 mm in diameter with wedge‐shaped cone‐scale complexes, at least 18 mm long by 8 mm wide and with narrow wings and a short apical spine. The ovules sit centrally in a distinct hollow on the cone‐scale complex surface but… 

Diversification of crown group Araucaria: the role of Araucaria famii sp. nov. in the mid-Cretaceous (Campanian) radiation of Araucariaceae in the Northern Hemisphere.

This small cone with attached, imbricate leaves, wide bracts, and unusually large seeds, most closely resembles those of Araucaria Section Eutacta, providing important new insights into the structure and relationships of Cretaceous Northern Hemisphere Araucariaceae.

Emwadea microcarpa gen. et sp. nov.—anatomically preserved araucarian seed cones from the Winton Formation (late Albian), western Queensland, Australia

The cones are small, prolate ellipsoidal with wedge-shaped cone scales bearing winged seeds attached adaxially to the scale only by tissues surrounding the vasculature entering the ovule, testifying to placement within the Araucariaceae.

New Insights into the Evolution of Mucilage Cells in Araucariaceae: Araucaria violetae sp. nov. from the Early Cretaceous Araripe Basin (Northeast Brazil)

Premise of research. Araucariaceae are currently disjunctively distributed over the Southern Hemisphere, dominating only some restricted habitats. In contrast, fossil representatives of this group

Pollen Grains Found in Pollen Cones of Schidolepium Heer (Pinopsida) from the Middle Jurassic of East Siberia, Russia

Premise of research. Jurassic localities of fossil flora in the Irkutsk Region (East Siberia) are rich in reproductive remains of gymnosperms with in situ pollen. Our aim was to understand the

The record of Araucariaceae macrofossils in New Zealand

Pole, M., December, 2008. The record of Araucariaceae macrofossils in New Zealand. Alcheringa 32, 405–426. ISSN 0311-5518. The Araucariaceae have a long record in New Zealand, extending back to the

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

Fossils from the Ligorio Márquez Formation of Santa Cruz, Patagonia, Argentina 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.

Did Kauri (Agathis: Araucariaceae) really survive the Oligocene drowning of New Zealand?

New Zealand (NZ) is both a Gondwanan continental fragment and a geologically active oceanic island, and hence, unravelling the origins and diversification of its biota has been considered important

Organization, anatomy, and fungal endophytes of a Triassic conifer embryo.

Preservation of fossil embryos, although rare, can expand the array of characters available in tracing the evolutionary history of plants as well as increase knowledge of voltzialean anatomy and morphology.

Persistent biotic interactions of a Gondwanan conifer from Cretaceous Patagonia to modern Malesia

A suite of blotch mines, galls, scale-insect covers, and rust fungus that re-occur on the same host genus through time and space are reported, showing the persistence of ecological guilds and possible host-tracking across major plate movements since the late Mesozoic.



Upper Cretaceous Araucarian Cones from Hokkaido and Saghalien: Araucaria nipponensis Sp. Nov.

Six ovulate, permineralized cones, four cone-scale complexes, and one isolated seed are described from the Upper Cretaceous Upper Yezo and Miho Groups from Hokkaido, Japan, and Saghalien, Russia.

Anatomical study of the holotype of the ovulate cone Araucaria sphaerocarpa Carruthers reveals excellently preserved cone and seed tissues in spite of the fragmentary nature of the fossil remains.

Araucarites Bindrabunensis sp. nov., a petrified megastrobilus from the Jurassic of Rajmahal Hills, Bihar

Under the name Araucarites bindrabunensis sp. nov. two specimens of petrified araucarian megastrobili are described from the Raj mahal Hills. Bihar. The megastrobili are ellipsoid in form and bear

Yezonia, a new section ofAraucaria (Araucariaceae) based on permineralized vegetative and reproductive organs ofA. vulgaris comb. nov. from the upper cretaceous of Hokkaido, Japan

A reconstructed plant,Araucaria vulgaris, supports the theory that an araucarian plant that boreBrachyphyllum-like foliage and aEutacta-like seed cone was predicted by Harris in 1979 and proves the presence of an extinct characteristic-form of the genus.

Some Morphological Features of Wollemi Pine (Wollemia nobilis: Araucariaceae) and Their Comparison to Cretaceous Plant Fossils

Reexamination of Mesozoic and Tertiary paleofloras will most probably reveal an important contribution of Wollemia to the fossil record of Araucariaceae.


The Lower Cretaceous sediments in Patagonia (Barremian-Albian) contain abundant grains which were referred to lnaperturopollenites limbatus in the literature. Good specimens show that this type has a

Conifers from the Upper Cretaceous of Cape Lamb, Vega Island, Antarctica

Abstract A fragment of an araucarian ovuliferous cone, araucarian leaves and podocarpaceous wood are described from Upper Cretaceous strata exposed at Cape Lamb, Vega Island, Antarctica. The wood
