A new fossil species of Corylopsis (Hamamelidaceae), C. grisea Quirk & Hermsen sp. nov, based on seeds from the early Pliocene Gray Fossil Site (GFS), eastern Tennessee, USA, is described. The assignment of the seeds to Hamamelidaceae, subfamily Hamamelidoideae, is based on the overall size of the seeds, smooth testa, lack of a seed wing, and the presence of a terminal hilar scar. The assignment to the genus Corylopsis is based on seed size as well as the presence of a hilar facet, in addition…

The presence of fossil passifloroid seeds in Europe shows that Passifloroideae once occurred in that region, although they are no longer found there today.
Plant and invertebrate macrofossils from the Pipe Creek Sinkhole (Late Neogene), Grant County, Indiana
ABSTRACT Examination of macrofossils from the late Neogene Pipe Creek Sinkhole in Indiana, USA, yielded 15 distinct plant taxa, one fungal taxon, and six invertebrate taxa. The plant assemblage was


Anatomically Preserved Seeds of Corylopsis (Hamamelidaceae) from the Miocene of Yunnan, China, and Their Phytogeographic Implications
Lignitized seeds from the Early to Middle Miocene of Yunnan Province, southwestern China, are assigned to the genus Corylopsis (Hamamelidaceae) on the basis of morphological and anatomical details.
Fossil Corylopsis and Fothergilla Leaves (Hamamelidaceae) from the Lower Eocene Flora of Republic, Washington, U.S.A., and Their Evolutionary and Biogeographic Significance
The occurrence at Republic of these two hamamelid plants underscores the diversity of the northwestern “Okanogan Highlands” flora of British Columbia, Canada, and Washington State, and demonstrates the Early Eocene presence of two disjunct Hamamelid genera.
First fossil record of Staphylea L. (Staphyleaceae) from North America, and its biogeographic implications
According to the paleogeographic distribution of the genus, it is hypothesized that Staphylea originated from western Eurasia no later than the late Oligocene, and arrived in eastern North America most possibly through the North Atlantic land bridges like many other seed plants.
New fossil fruits of Carya (Juglandaceae) from the latest Miocene to earliest Pliocene in Tennessee, eastern United States
Fossil fruits including nuts and associated husk valves of a new species of Carya (Juglandaceae) are described from the latest Miocene to earliest Pliocene in northeastern Tennessee, eastern United
Late Hemphillian Colubrid Snakes (Serpentes, Colubridae) from the Gray Fossil Site of Northeastern Tennessee
The Gray Fossil Site of northeastern Tennessee represents a poorly understood region of North America at a crucial time period in snake evolution, and its study may help to further understand the modern snake fauna present today in midcontinental and eastern North America.
Allonia decandra: Floral remains of the tribeHamamelideae (Hamamelidaceae) from Campanian strata of southeastern USA
The occurrence of fossils assignable to Loropetalinae during the Campanian documents the existence of Hamamelidaceae with a level of floral organization and character evolution equivalent to that of extant genera, early in the evolutionary history of the family.
First occurrence of the enigmatic peccaries Mylohyus elmorei and Prosthennops serus from the Appalachians: latest Hemphillian to Early Blancan of Gray Fossil Site, Tennessee
The GFS represents the only site outside the Palmetto Fauna of Florida with M. elmorei, greatly expanding the species range north over 920 km, well into the Appalachian region, and mandibular material from the GFS for P. serus exhibited larger dentitions and a greater degree of robustness than currently recognized for the species.
A new species of Gulo from the Early Pliocene Gray Fossil Site (Eastern United States); rethinking the evolution of wolverines
Detailed comparison indicates Plesiogulo, which has often been suggested to be ancestral to Gulo, is not likely closely related to gulonines, and instead may represent convergence on a similar niche, which suggests wolverines may have become ‘cold-adapted’ relatively recently.
