A eudicot leaf from the Lower Cretaceous (Aptian, Araripe Basin) Crato Konservat‐Lagerstätte Open

Edlley Pessoa, Alexandre C. Ribeiro, Nathan A. Jud · 2021

Premise The Crato Konservat‐Lagerstätte in Brazil preserves an exceptionally rich assemblage of plant macrofossils from the Early Cretaceous (late Aptian), including rare early angiosperm fossils related to Nymphaeales, monocots, and magno…

Climbing since the early Miocene: The fossil record of Paullinieae (Sapindaceae) Open

Nathan A. Jud, Sarah E. Allen, Chris W. Nelson, Carolina Lopes Bastos, Joyce G. Chery · 2021

Paullinieae are a diverse group of tropical and subtropical climbing plants that belong to the soapberry family (Sapindaceae). The six genera in this tribe make up approximately one-quarter of the species in the family, but a sparse fossil…

Fossil evidence from South America for the diversification of Cunoniaceae by the earliest Palaeocene Open

Nathan A. Jud, María A. Gandolfo · 2020

Background and Aims Cunoniaceae are woody plants with a distribution that suggests a complex history of Gondwanan vicariance, long-distance dispersal, diversification and extinction. Only four out of ~27 genera in Cunoniaceae are native to…

Azolla Sporophytes and Spores from the Late Cretaceous and Paleocene of Patagonia, Argentina Open

Elizabeth J. Hermsen, Nathan A. Jud, Facundo De Benedetti, María A. Gandolfo · 2019

Premise of research. While Azolla has a rich fossil record based on dispersed megaspore apparatuses and microspore massulae, fossil sporophytes are relatively rare. In this contribution, we describe two fossil Azolla species based on both …

A vision for historical biogeography Open

Nathan A. Jud · 2019

A new fossil assemblage shows that large angiosperm trees grew in North America by the Turonian (Late Cretaceous) Open

Nathan A. Jud, Michael D. D’Emic, Scott A. Williams, Josh C. Mathews, Katie Tremaine , et al. · 2018

Fossils from Utah show large flowering trees evolved at least 15 million years earlier than previously thought.

Fossil moonseeds from the Paleogene of West Gondwana (Patagonia, Argentina) Open

Nathan A. Jud, Ari Iglesias, Peter Wilf, María A. Gandolfo · 2018

Premise of the Study The fossil record is critical for testing biogeographic hypotheses. Menispermaceae (moonseeds) are a widespread family with a rich fossil record and alternative hypotheses related to their origin and diversification. T…

Fossil flowers from the early Palaeocene of Patagonia, Argentina, with affinity to Schizomerieae (Cunoniaceae) Open

Nathan A. Jud, María A. Gandolfo, Ari Iglesias, Peter Wilf · 2017

An extinct genus of crown-group Cunoniaceae is recognized and placed along the stem lineage leading to Schizomerieae. Extant relatives are typical of tropical to southern-temperate rainforests, and these fossils likely indicate a similarly…

Panascleroticoxylon crystallosa gen. et sp. nov.: a new Miocene malpighialean tree from Panama Open

Oris Rodríguez-Reyes, Peter Gasson, Carolyn Thornton, Howard J. Falcon‐Lang, Nathan A. Jud · 2017

We report fossil wood specimens from two Miocene sites in Panama, Central America: Hodges Hill (Cucaracha Formation; Burdigalian, c. 19 Ma) and Lago Alajuela (Alajuela Formation; Tortonian, c. 10 Ma), where material is preserved as calcic …

Flowering after disaster: Early Danian buckthorn (Rhamnaceae) flowers and leaves from Patagonia Open

Nathan A. Jud, María A. Gandolfo, Ari Iglesias, Peter Wilf · 2017

Southern-Hemisphere terrestrial communities from the early Paleocene are poorly known, but recent work on Danian plant fossils from the Salamanca Formation in Chubut Province, Argentina are providing critical data on earliest Paleocene flo…

A liana from the lower Miocene of Panama and the fossil record of Connaraceae Open

Nathan A. Jud, Chris W. Nelson · 2017

PREMISE OF THE STUDY: Permineralized wood is common in the Miocene beds exposed during the expansion of the Panama Canal. We describe a stem with the distinctive anatomy of a liana and evaluate the evolutionary, biogeographic, and ecologic…

Angiosperm wood from the Upper Cretaceous (Coniacian) of British Columbia, Canada Open

Nathan A. Jud, Elisabeth A. Wheeler, Gar W. Rothwell, Ruth A. Stockey · 2017

Fossil angiosperm wood was collected from shallow marine deposits in the Upper Cretaceous (Coniacian) Comox Formation on Vancouver Island, British Columbia, Canada. The largest specimen is a log at least 2 m long and 38 cm in diameter. Thi…

Integrated Chronology, Flora and Faunas, and Paleoecology of the Alajuela Formation, Late Miocene of Panama Open

Bruce J. MacFadden, D. S. Jones, Nathan A. Jud, Jorge W. Moreno-Bernal, Gary Morgan , et al. · 2017

The late Miocene was an important time to understand the geological, climatic, and biotic evolution of the ancient New World tropics and the context for the Great American Biotic Interchange (GABI). Despite this importance, upper Miocene d…

Erratum: Corrigendum: Holocene shifts in the assembly of plant and animal communities implicate human impacts Open

S. Kathleen Lyons, Kathryn L. Amatangelo, Anna K. Behrensmeyer, Antoine Bercovici, Jessica L. Blois , et al. · 2016

Fruits and wood of Parinari from the early Miocene of Panama and the fossil record of Chrysobalanaceae Open

Nathan A. Jud, Chris W. Nelson, Fabiany Herrera · 2016

PREMISE OF THE STUDY: Chrysobalanaceae are woody plants with over 500 species in 20 genera. They are among the most common trees in tropical forests, but a sparse fossil record has limited our ability to test evolutionary and biogeographic…

RECONSTRUCTION OF PALEOECOLOGY AND WHOLE-PLANT HABIT USING STABLE CARBON ISOTOPES FROM DISPERSED LEAVES OF LAUROZAMITES POWELLII, AN UPPER TRIASSIC BENNETTITALEAN Open

Karl C. Fetter, Nathan A. Jud, Nathan A. Jud, Richard S. Barclay, Richard S. Barclay , et al. · 2016

Fossil evidence for a herbaceous diversification of early eudicot angiosperms during the Early Cretaceous Open

Nathan A. Jud · 2015

Eudicot flowering plants comprise roughly 70% of land plant species diversity today, but their early evolution is not well understood. Fossil evidence has been largely restricted to their distinctive tricolpate pollen grains and this has l…
