Many of the oldest definitive members of the Rosaceae are present in the Eocene upland floras of the Okanogan Highlands of northeastern Washington State and British Columbia, Canada. Over a dozen rosaceous taxa representing extant and extinct genera of all four traditionally recognized subfamilies are known from flowers, fruits, wood, pollen, and especially leaves. The complexity seen in Eocene Rosaceae suggests that hybridization and polyploidy may have played a pivotal role in the early… 
Fruit fossils of Rosoideae (Rosaceae) from the late Pliocene of northwestern Yunnan, Southwest China
TLDR
The Rubus fossils suggest that Rubus was already establishing its modern diversity in northwestern Yunnan during the late Pliocene, which is thought to be largely driven by dramatic mountain uplifts and environmental complications associated with the southeastern extension of the Tibetan Plateau.
Fruits of icacinaceae (tribe iodeae) from the late paleocene of Western north america.
TLDR
These new records from the Almont/Beicegel Creek flora in North Dakota and several localities in Wyoming, Colorado, and Montana complement records known from the Early Eocene of England and document an increased diversity of Iodeae and related forms in the Paleogene of western North America.
New plant fossil records and paleoclimate analyses of the late Pliocene Citronelle Formation flora, U.S. Gulf Coast
The late Pliocene was an important time of relatively recent global warmth, and it heralded the end of Neogene Epoch. However, plant fossils from this time are uncommon in North America. This study
Biotic processes in the Okanagan Highlands floras: possible evidence of hybridization in plants adapting to a temperate forest
Hybridization is a key mechanism for increased diversification and speciation among modern plants and is especially important in certain families such as Rosaceae and Anacardiaceae. This mechanism is
A review of paleobotanical studies of the Early Eocene Okanagan (Okanogan) Highlands floras of British Columbia, Canada, and Washington, USA
The history of plant fossil collecting in the Okanagan (Okanogan) Highlands of British Columbia and northeastern Washington is closely intertwined with the history of geological surveys and mining
Leaf Architecture of Extant Species of Rosa L. and the Paleogene Species Rosa lignitum Heer (Rosaceae)
TLDR
Detailed leaf morphology of Rosa again supports the previous assumption that the zonal vegetation of the central European Oligocene is partly comparable to extant forest types in Southeast Asia.
The Eocene mystery flower of McAbee, British Columbia
TLDR
A distinctive, extinct type of flower and fruit is described based on coalified compression and impression fossils from the Eocene lake bed deposits of McAbee, British Columbia that present a suite of characters not encountered in any known extant genus, and the familial affinities remain uncertain.
A review of the plants of the Princeton chert (Eocene, British Columbia, Canada)
TLDR
The history of Princeton chert plant research is outlined, starting with Boneham and others, and extending into studies by Stockey and her students and colleagues, and undertaken primarily at the University of Alberta, Edmonton.

Rosaceous Chamaebatiaria-like foliage from the Paleogene of western North America
TLDR
Analysis of the foliar and reproductive characters of the extant species of these genera indicates that the two genera could be closely related and the assignment of Chamaebatia to Rosoideae invalid.
Betula leaves and reproductive structures from the Middle Eocene of British Columbia, Canada
TLDR
Fossil angiosperm leaves from the Middle Eocene Allenby Formation, at One Mile Creek near Princeton, southern British Columbia, are described and assigned to Betula leopoldae Wolfe & Wehr and suggest that the vegetative and reproductive structures were produced by a single fossil species.

Paleorosa similkameenensis, gen. et sp. nov., permineralized flowers (Rosaceae) from the Eocene of British Columbia
TLDR
The flowers are permineralized with silicate and are found scattered through a matrix of black chert, suggesting affinities with the Rosaceae, specifically with the more primitive members of the tribes Maleae, Quillajeae, and Sorbarieae.
