Fossil fruits confirm that cornelian cherries (Cornus, subgenus Cornus) were established in the Northern Hemisphere in the Early Tertiary. We describe the oldest known member of the subgenus, Cornus piggae sp. n., on the basis of well‐preserved silicified endocarps from the late Paleocene of North Dakota. The endocarps are ellipsoidal, thin walled, and two to three locular, and they lack an axial longitudinal bundle. The septa and external walls of the fruit stone are riddled with cavities, a… Expand
The Early Phylogenetic Diversification of Cornales: Permineralized Cornalean Fruits from the Campanian (Upper Cretaceous) of Western North America
TLDR
Two permineralized fruits found within a single calcareous concretion from the Upper Cretaceous (upper Campanian) Spray Formation of Vancouver Island, British Columbia provide additional evidence for the initial phylogenetic diversification of Cornales. Expand
Cretaceous origin of dogwoods: an anatomically preserved Cornus (Cornaceae) fruit from the Campanian of Vancouver Island
TLDR
This fossil is the first evidence of crown-group Cornaceae from the Cretaceous and sheds light on both the plesiomorphic fruit characters and the timing of the initial diversification of the family and basal asterid lineage, Cornales. Expand
Anatomically preserved fossil cornalean fruits from the Upper Cretaceous of Hokkaido: Eydeia hokkaidoensis gen. et sp. nov.
TLDR
A new taxon of Cornales is described, Eydeia hokkaidoensis gen. et sp. Expand
Early diverging asterids of the Late Cretaceous: Suciacarpa starrii gen. et sp. nov. and the initial radiation of Cornales1
TLDR
Two permineralized cornalean fruits from the Campanian of the state of Washington in the northwestern United States were studied using the cellulose acetate peel technique and assigned to a new genus and species within Cornales, Suciacarpa starrii. Expand
Cornalean affinities, phylogenetic significance, and biogeographic implications of Operculifructus infructescences from the Late Cretaceous (Campanian) of Mexico.
TLDR
Operculifructus provides direct evidence for the occurrence of Grubbiaceae in the Late Cretaceous, much older than previous Eocene evidence. Expand
Filling the gaps in the Neogene plant fossil record of eastern North America: New data from the Pliocene of Alabama
Abstract Nine angiosperm taxa are described, based on megafossils from the Citronelle Formation of Alabama, that are significant in either clarifying previous identifications, or in providing theExpand
Tracking the Initial Diversification of Asterids: Anatomically Preserved Cornalean Fruits from the Early Coniacian (Late Cretaceous) of Western North America
TLDR
The diversity, geographic distribution, and stratigraphic age of these early cornaleans clearly indicate that the diversification of Cornales was well under way by the Coniacian, indicating new insights into the early evolution of asterids. Expand
Scanning electron microscopy investigations of middle to late Eocene pollen from the Changchang Basin (Hainan Island, South China) – Insights into the paleobiogeography and fossil history of Juglans, Fagus, Lagerstroemia, Mortoniodendron, Cornus, Nyssa, Symplocos and some Icacinaceae in SE Asia
TLDR
The two Iodes types, one resembling African/Mad Madagascar taxa and one a Melanesian taxon, suggest that the Old World disjunction of Iodes in Africa/Madagascar and SE Asia is a Paleogene relict, whereas the third Icacinaceae taxon resembles two genera of the Mappia/Nothapodytes clade, where M appia occurs today in Central America and Nothapodtes in SE Asia.

Combined LM and SEM study of the middle Miocene (Sarmatian) palynoflora from the Lavanttal Basin, Austria: Part V. Magnoliophyta 3 – Myrtales to Ericales
TLDR
Köppen signatures of potential modern analogues of the additional fossil woody elements confirm the hypothesis of a subtropical climate at lower elevations and subsequent transition into a temperate climate with altitudinal succession. Expand
Combined LM and SEM study of the middle Miocene (Sarmatian) palynoflora from the Lavanttal Basin, Austria: part IV. Magnoliophyta 2 – Fagales to Rosales
TLDR
Köppen signatures of potential modern analogues of the fossil Fagales and Rosales suggest a subtropical climate at lower elevation and subsequent subtropICAL to temperate climate with altitudinal succession in the Lavanttal area during accumulation of the palynoflora. Expand

Leaves of Cornus (Cornaceae) from the Paleocene of North America and Asia Confirmed by Trichome Characters
TLDR
Reexamination of previously described Cornus leaves from the Paleocene of the Rocky Mountains and Great Plains region leads us to reject Cornus nebrascensis Schimper (=Cornus newberryi Hollick) from the genus, and recognizes two new Paleocene species, whose identity as Cornus is confirmed by the presence of characteristic trichomes and venation.

Cornus eydeana (Cornaceae), A New Cornelian Cherry from China—Notes on Systematics and Evolution
TLDR
A new species of cornelian cherry is described from southeastern Yunnan, China that appears most similar to the African species C. volkensii Harms, but pollen morphology and geographic distributions suggest a closer affinity with the Eurasian species. Expand
Leaves and Fruits of Davidia (Cornales) from the Paleocene of North America
TLDR
It is established that extant Davidia had evolved by the Paleocene, prior to the first known occurrences of Nyssa in the Eocene, and was a contemporary of the extinct nyssoid genus Amersinia. Expand
Hironoia fusiformis gen. et sp. nov.; a cornalean fruit from the Kamikitaba locality (Upper Cretaceous, Lower Coniacian) in northeastern Japan
TLDR
The recognition of an unequivocal cornalean fruit in the Early Coniacian–Early Santonian of Japan provides the earliest record of this group in the fossil record and establishes a minimum age for the early divergence of the asterid clade, a major group of living angiosperms comprising more than a third of all species of extant flowering plants.

Palaeocarpinus dakotensis sp.n. (Betulaceae: Coryloideae) and Associated Staminate Catkins, Pollen, and Leaves from the Paleocene of North Dakota
TLDR
Characters that were previously unknown for the genus are described from anatomically preserved specimens, supporting earlier suggestions that Palaeocarpinus combines features found separately in the extant Coryleae and Carpineae. Expand
PHYLOGENY, BIOGEOGRAPHY, AND MOLECULAR DATING OF CORNELIAN CHERRIES (CORNUS, CORNACEAE): TRACKING TERTIARY PLANT MIGRATION
TLDR
The hypothesis that the NALB served as an important land bridge connecting the North American and European floras, as well as connecting American and African floras via Europe during the early Tertiary is supported. Expand
Species level phylogeny of the genus Cornus (Cornaceae) based on molecular and morphological evidence-implications for taxonomy and Tertiary intercontinental migration
TLDR
The phylogeny based on the total evidence tree including fossils supports an origin and early Tertiary diversification of Cornus in Europe and multiple trans-Atlantic migrations between Europe and North America by the early TERTiary. Expand

TLDR
Cornus, nyssoids, and mastixioids (modernMastixia and its closest fossil allies) are here regarded as the true Cornaceae, and other genera once thought to be cornaceous are doubtfully to not at all related. Expand
