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…

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.

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.

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.

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.

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.
