Premise of research. A new Early Jurassic species of Cupressaceae is reconstructed from the Cañadón Asfalto Formation in Argentina, based on impressions of foliage and attached and dispersed seed and pollen cones. Methodology. Over 230 specimens were examined using reflected-light microscopy and epifluorescence. Relevant extant taxa were studied for structural comparisons using herbarium specimens and living material from botanical gardens. Relationships of the new conifer were assessed in the… 
Ancient diversity and turnover of cunninghamioid conifers (Cupressaceae): two new genera from the Upper Cretaceous of Hokkaido, Japan
Two additional cunninghamioid genera are characterized on the basis of permineralized seed cones from the Upper Cretaceous of Hokkaido, Japan, demonstrating a mosaic of characters that are not seen in any reported conifer of Cupressaceae.
Conifer Diversity in the Middle Triassic: New Data from the Fossillagerstätte Kühwiesenkopf/Monte Prà della Vacca (Pelsonian, Anisian) in the Dolomites (Northeastern Italy)
Premise of research. The Triassic is considered a pivotal time for the radiation of modern conifer families. In this article, we describe the conifers from the Fossillagerstätte Kühwiesenkopf/Monte
Late Cretaceous Diversification of Cupressaceous Conifers: A Taiwanioid Seed Cone from the Eden Main, Vancouver Island, British Columbia, Canada
This cone shows similarities in overall structure and vasculature to those of living Taiwania (Cupressaceae), however, the fossil cone size is generally larger, with six seeds per scale versus two, and seeds are extremely large and fleshy with a unique submicropylar structure.
Three new Cenomanian conifers from El Chango (Chiapas, Mexico) offer a snapshot of the geographic mosaic of the Mesozoic conifer decline
These fossils fill in gaps in the evolutionary history of lineages like Microcachrys, which are demonstrated occurred in the Northern hemisphere before becoming restricted to its current range (Tasmania) and support the hypothesis of a geographically and ecologically structured “rise of angiosperms”.


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.
Towards a whole plant reconstruction for Austrohamia (Cupressaceae): New fossil wood from the Lower Jurassic of Argentina
Permineralized woods from the same strata where Austrohamia minuta was found in the Canadon Asfalto Basin, Chubut Province, Argentina are described, and a new specific taxon for the Patagonian specimens is proposed.
Whole-Plant Reconstruction and Updated Phylogeny of Austrohamia acanthobractea (Cupressaceae) from the Middle Jurassic of Northeast China
The morphological cladistic analysis suggests that the two species of Austrohamia form a polytomy with the expanded Cunninghamioideae clade, which includes extant Cunninghamia and Cunninghamia-like fossils from the Jurassic, Cretaceous, and Cenozoic.
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 Athrotaxites (Athrotaxoideae, cupressaceae) from the upper cretaceous raritan formation, New Jersey, USA
Based on the combination of characters such as ovuliferous complex morphology, arrangement of vascular tissues and resin canals, seed number and their morphology, orientation and disposition, these fossils are placed within a new species of the fossil genus Athrotaxites.
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.
Middle Jurassic evidence for the origin of Cupressaceae: A paleobotanical context for the roles of regulatory genetics and development in the evolution of conifer seed cones.
A new and distinct seed-cone from the Isle of Skye in western Scotland provides the oldest detailed evidence for the ancestral morphology of the phylogenetically contentious family Cupressaceae and helps to clarify the sequence of structural changes that occurred during the transition from ancestral voltzialean conifers to morphologically recognizable Cupressidae.
Stockeystrobus gen. nov. (Cupressaceae), and the evolutionary diversification of sequoioid conifer seed cones1
An anatomically preserved seed cone from Late Cretaceous (Santonian–Coniacian) sediments of the Yezo Group on the Japanese Island of Hokkaido documents additional diversity among sequoioid conifers,
A new Cheirolepidiaceae (Coniferales) from the Early Jurassic of Patagonia (Argentina): Reconciling the records of impression and permineralized fossils.
Pararaucaria taquetrensis represents the oldest known Cheirolepidiaceae seed cones from the Southern Hemisphere, and this material highlights the importance of compression and impression fossils in understanding the distribution of fossil taxa.
A new species of the extinct genus Austrohamia (Cupressaceae s.l.) in the Daohugou Jurassic flora of China and its phytogeographical implications
The presence of similar, if not identical taxa, on both sides of the Pacific indicates the cosmopolitan distribution of primitive Cupressaceae between East Asia (Eurasia) and South America in the Pangaea.
