Premise of research. The extinct conifer genus Schizolepidopsis is characterized by deeply bilobed ovuliferous scales bearing two adaxial seeds. Although it is frequently placed in Pinaceae, the evidence for a close relationship with the family is mixed. Resolving the affinities of Schizolepidopsis has important implications for the age of Pinaceae because putative reports of the genus extend into the Late Permian. We describe a new species, Schizolepidopsis ediae sp. nov., based on specimens…

Early Cretaceous abietoid Pinaceae from Mongolia and the history of seed scale shedding.
The earliest and best-documented evidence of a "shedder" seed cone from the Aptian-Albian of Mongolia is described and the exquisite preservation of the trichomes in L. mellonae raises questions about their potential ecological function in the cones of fossil and living Pinaceae.
A permineralized Early Cretaceous lycopsid from China and the evolution of crown clubmosses.
Recognition of Lycopodicaulis in Asia during the Early Cretaceous indicates the presence of crown Lycopodiaceae at this time, and striking similarities of stem anatomy with extant species provide a framework for the understanding of the interaction of branching and vascular anatomy in crown-group lycopsids.

Pinaceae-like reproductive morphology in Schizolepidopsis canicularis sp. nov. from the Early Cretaceous (Aptian-Albian) of Mongolia.
Schizolepidopsis canicularis produced winged seeds that formed in a manner that is unique to Pinaceae among extant conifers, and may potentially help reconcile the appearance of the family in the fossil record with results based on phylogenetic analyses of molecular data.
New species of the genus Schizolepidopsis (conifers) from the Albian of the Russian high Arctic and geological history of the genus
It is likely that Schizolepidopsis plants became extinct close to the Albian-Cenomanian boundary due to competitive replacement by more advanced pinaceous conifers possessing compact cones with densely arranged seed scales that ensured better ovule protection.
The seed cone Eathiestrobus gen. nov.: fossil evidence for a Jurassic origin of Pinaceae.
An anatomically preserved fossil conifer seed cone described here extends the stratigraphic range of Pinaceae nearly 30 million years, thus reducing the apparent discrepancy between evidence from the fossil record and inferences from systematic studies of living species.
A New Voltzian Seed Cone from the Early Cretaceous of Mongolia and Its Implications for the Evolution of Ancient Conifers
Krassilovia mongolica provides evidence of the additional diversity of extinct voltzian conifers and shows that some persisted to inhabit forest-moor swamp environments in eastern Asia during the Early Cretaceous.
A New Species of the Extinct Genus Schizolepis from the Jurassic Daohugou Flora, Inner Mongolia, China with Special Reference to the Fossil Diversity and Evolutionary Implications
: Schizolepis daohugouensis sp. nov. is described from the Jurassic sediments of Daohugou flora, from Ningcheng County, Inner Mongolia Autonomous Region, China. The female cone is slender,
Hanskerpia gen. nov. and phylogenetic relationships among the most ancient conifers (Voltziales)
Numerical cladistic analysis reveals that this novel combination of characters defines a new fossil plant genus and species of walchian conifers Hanskerpia hamiltonensis, and supports some previously proposed relationships among the most primitive conifer and other Paleozoic coniferophytes.
A new genus of the Cupressaceae (sensu lato) from the Jurassic of Patagonia: Implications for conifer megasporangiate cone homologies
This conifer possesses a combination of characters indicating placement within the basal Cupressaceae ( i.e. the former “Taxodiaceae”) and is supported by a phylogenetic analysis that places the Argentinean fossil close to the extant genera Athrotaxis and Cunninghamia and the fossil genera Elatides and Sewardiodendron.
A lower Cretaceous (Valanginian) seed cone provides the earliest fossil record for Picea (Pinaceae).
This description of an anatomically preserved seed cone extends the fossil record of Picea to the Valanginian Stage of the Early Cretaceous, thereby resolving a ghost lineage predicted by molecular divergence analyses, and offers new insight into the evolution of Pinaceae.
Whole-Plant Reconstruction and Phylogenetic Relationships of Elatides zhoui sp. nov. (Cupressaceae) from the Early Cretaceous of Mongolia
Elatides zhoui provides further evidence for the diversity of Cupressaceae sensu lato during the Cretaceous and supports the hypothesis that cunninghamioid conifers in particular were diverse and widespread during the early evolution of the Cupressidae.
A new species of Pityostrobus (Pinaceae) from the Cretaceous of California: moving towards understanding the Cretaceous radiation of Pinaceae
A new pinaceous cone from the Early Cretaceous of California is described as Pityostrobus pluriresinosa sp.
