The Southern Hemisphere conifer family Araucariaceae has a very restricted present day distribution, but was more widespread in the past. The genusAraucaria is represented by good fossil material in both hemispheres as early as the Jurassic, whileAgathis is only known from the Southern Hemisphere beginning in the Cretaceous. Cuticle studies of extant araucarians have enabled accurate comparisons of fossil leaves to living taxa.Araucaria SectionBunya is represented by cones of several types in… 

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,

New Araucarian Conifer from the Late Cretaceous (Campanian-Maastrichtian) of Southeastern Turkey

A new fossil conifer Araucaria rothwellii J.Kvaček from the Campanian-Maastrichtian marine sediments of the Bozova Formation in southeastern Turkey is described based on leaf compressions and leaf impressions, similar in macro- and micromorphology to extant A. bidwillii, which is indigenous to Queensland in northeast Australia.

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

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.

Agathis (Araucariaceae) macrofossils from Cainozoic sediments in south-eastern Australia

Intraspecific variation in leaf cuticle morphology is examined in extant A. macrophylla in particular, and is found to be much higher than previously recorded, and this makes assignment of fossil Agathis leaves to species difficult.

Gymnosperms from the Lower Cretaceous Crato Formation (Brazil). I. Araucariaceae and Lindleycladus (incertae sedis)

Fossil conifers from the Early Cretaceous, most likely late Aptian, Crato Formation were studied and members of two conifer taxa were recognized, interpreted as adaptations to a warm seasonally dry climate.


A bract-scale complex attributable to Araucaria is described from the Lower Jurassic Portland Formation of Massachusetts, becoming the first bona fide megafossil of the Araucariaceae from the Newark Supergroup and one of the few early Mesozoic examples from all of North America.

Eocene Araucaria Sect. Eutacta from Patagonia and floristic turnover during the initial isolation of South America.

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



The Araucariaceae: An evolutionary perspective

Tertiary Araucarian Macrofossils From Tasmania

These species confirm the presence of the subtropical/tropical Araucariaceae in Tasmania in the Eocene and the evolutionary position of the fossil species is uncertain at present.

Cuticular studies of broad multiveined leafed conifers from the Victorian Lower Cretaceous using SEM and light microscopy confirm the presence of the Araucariaceae and allow discrimination of six new species that show affinities to the extant sections of Araucaria.

Araucaria (Araucariaceae) species from Australian tertiary sediments — a micromorphological study

  • 1990
The cuticular micromorphology of four existing and four new species of Araucaria from Australian Tertiary sediments is examined using scanning electron microscopy and suggests that complex araucarian forests similar to those found today in New Caledonia may have been more widespread in the region in the past.

Tertiary gymnosperms from Tasmania : Araucariaceae.

Three new species of the Araucariaceae are described from leaf remains, Araucaria readiae from the Early Eocene Regatta Point flora, A. hastiensis from the Middle-Late Eocene Hasties flora, and Agathis tasmanica from the early Oligocene-Early Miocene Little Rapid River flora, indicating the presence of a high diversity of araucarian species in the region in the Early-Middle Tertiary.

Antarctic and Gondwana Conifers

In Antarctica, the study of fossil plants in general and the conifers in particular is in its infancy, while the potential for work in this area is enormous. Because of its unique position in

Early Tertiary Podocarpaceae: Megafossils from the Eocene Anglesea Locality, Victoria, Australia

Fossil Podocarpaceae from the Eocene Anglesea locality in Victoria are described and assigned to six species from five modern genera using cuticular and other vegetative morphology.

Tertiary Araucariaceae From South-Eastern Australia, With Notes on Living Species

The foliage shoots, male cones, and female cone-scales of a new Tertiary species of Araucaria, section Eutacta, from the brown coal at Yallourn, Victoria, have been described; leaves and male and
