PREMISE Exceptional anatomical preservation of a fossil araucarian seed cone from a marine carbonate concretion from Vancouver Island, British Columbia, Canada provides unusually complete evidence for cone structure including seeds, megagametophytes, microgametophytes, and embryos of an Upper Cretaceous (Campanian) species of Araucaria, providing important new insights into the structure and relationships of Cretaceous Northern Hemisphere Araucariaceae. METHODS The cone was studied from… Expand

Callialastrobus sousai gen. et sp. nov., a new araucariaceous pollen cone from the Early Cretaceous of Catefica (Lusitanian Basin, western Portugal) bearing Callialasporites and Araucariacites pollen
TLDR
The new genus Callialastrobus is established here to accommodate araucariaceous pollen cones containing both Araucariacites and Callialasporites pollen-types in situ. Expand

Upper Cretaceous Araucarian cones from Hokkaido : Araucaria nihongii sp. nov
TLDR
Ten small, permineralized cones 3.0–4.2 cm in diameter are described from the Late Cretaceous Upper Yezo Group of Hokkaido, Japan and are described as representing a new species of araucarian cone, Araucaria nihongii Stockey, Nishida et Nishida sp. Expand
AN ARAUCARIAN CONIFER BRACT-SCALE COMPLEX FROM THE LOWER JURASSIC OF MASSACHUSETTS: IMPLICATIONS FOR ESTIMATING PHYLOGENETIC AND STRATIGRAPHIC CONGRUENCE IN THE ARAUCARIACEAE
TLDR
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. Expand
Wairarapaia mildenhallii gen. et sp. nov., a New Araucarian Cone Related to Wollemia from the Cretaceous (Albian‐Cenomanian) of New Zealand
TLDR
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 of New Zealand, which supports the notion that many records of Araucaria‐like fossils represent basal lineages within the Araucariaceae rather than extinct members of the genus AraUCaria.

Yezonia, a new section ofAraucaria (Araucariaceae) based on permineralized vegetative and reproductive organs ofA. vulgaris comb. nov. from the upper cretaceous of Hokkaido, Japan
TLDR
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. Expand
Gymnosperms from the Lower Cretaceous Crato Formation (Brazil). I. Araucariaceae and Lindleycladus (incertae sedis)
TLDR
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. Expand
A New Female Cone,Araucaria beipoiaoensis sp.nov.from the Middle Jurassic Tiaojishan Formation,Beipiao,Western Liaoning,China and Its Evolutionary Significance
TLDR
The morphology and structure of the cone shows a close relationship to the araucarian cones of fossil and living genera but differs from any known species, and has important significance for the evolution of the Family Araucariaceae. Expand
Mesozoic Araucariaceae: Morphology and systematic relationships
TLDR
Evidence that fossil araucarian cones may have produced seeds with hypogeal germination is discussed in light of recent work on germination of extant bunya seedlings and the discovery of new fossil shoots from the Jurassic Morrison Formation of Utah. Expand
Anatomically Preserved Williamsonia (Williamsoniaceae): Evidence for Bennettitalean Reproduction in the Late Cretaceous of Western North America
TLDR
An anatomically preserved ovulate cycadeoid cone has been discovered in Upper Cretaceous sediments of Vancouver Island, British Columbia, Canada and reveals new features for the family Williamsoniaceae and allows for the interpretation of several additional facets of reproductive biology in the Bennettitales, particularly pollen tube production, pollination biology, and mode of fertilization.

Abstract Araucarian conifer remains from the Upper Cretaceous Ingersoll shale Konservat-Lagerstatte (Eutaw Formation) of Alabama include shoots of Araucaria bladenensis , an associated pollen cone,Expand
