Abstract

This study focuses on morphometric and systematic analyses of the fossil Vitis seeds, recovered from the Gray Fossil Site (7-4.5 Ma, latest Miocene-earliest Pliocene), northeastern Tennessee, U.S.A. A multivariate analysis based on eleven measured characters from 76 complete fossil seeds recognizes three morphotaxa. Further comparisons with both selected modern and fossil vitaceous specimens confirm that these morphotaxa represent three new species, viz. Vitis grayensis sp. nov.. Vitis lanatoides sp. nov., and Vitis latisulcata sp. nov. Furthermore, the close resemblance of the first two fossil grapes (V. grayensis and V. lanatoides) with two East Asian Vitis species provides further support concerning a strong eastern Asian aspect of the Gray fossil biota in the late Neogene southeastern North America, as previously evidenced by both animals (e.g. Pristinailurus bristoli [red panda]) and other plants (e.g. Sinomenium and Sargentodoxa).

Fossil moles from the Gray Fossil Site (Tennessee): Implications for diversification and evolution of North American Talpidae

Danielle E. Oberg, Joshua X. Samuels

Summary: This study describes new talpid specimens discovered at the Gray Fossil Site in Tennessee and analyzes their morphology using geometric morphometric analysis. The results show that humerus shape reflects locomotor ecology in extant talpids and provides insights into the ecology of fossil species. The study also compares the morphological data with molecular data, showing strong agreement between the two methods and improving the understanding of the evolutionary relationships within the talpid family.

Review of the Fossil Record of Passiflora, with a Description of New Seeds from the Pliocene Gray Fossil Site, Tennessee, USA

Elizabeth J. Hermsen

Summary: The study focuses on the fossil record of Passiflora and Passifloroideae, with a new fossil species based on seeds described. By examining fossil seeds, the research identified different subgeneric groups within Passiflora and reassigned two Miocene fossil seed species from Europe to Passifloroidesperma. The presence of fossil passifloroid seeds in Europe suggests a historical occurrence of Passifloroideae in the region.

Neogene Corylopsis seeds from eastern Tennessee

Zack J. Quirk, Elizabeth J. Hermsen

Summary: A new fossil species of Corylopsis, C. grisea, based on seeds from the early Pliocene Gray Fossil Site in eastern Tennessee, USA, extends the fossil record of Corylopsis in North America to the Neogene. The discovery supports the interpretation of GFS as a forested refugium that provided a relatively moist environment for subtropical to warm temperate plants during a time of cooling and drying. The presence of C. grisea at GFS also provides additional evidence for the biogeographic connection between the paleoflora at GFS and the modern flora of eastern Asia.

Deep-time biodiversity patterns and the dinosaurian fossil record of the Late Cretaceous Western Interior, North America

Susannah C. R. Maidment, Christopher D. Dean, Robert I. Mansergh, Richard J. Butler

Summary: Researchers found that while the raw data on ceratopsid and hadrosaurid dinosaurs strongly supported faunal provinciality, this result was primarily driven by sampling bias, and the data quality is currently inadequate for fair tests. Future studies should focus on smaller scale, higher resolution case studies to better control sampling bias.

Fossil frogs (Eleutherodactylidae: Eleutherodactylus) from Florida suggest overwater dispersal from the Caribbean by the Late Oligocene

Maria Camila Vallejo-Pareja, Edward L. Stanley, Jonathan Bloch, David C. Blackburn

Summary: The establishment of terrestrial vertebrate faunas in North America was influenced by various factors at different geographic scales. A study of anurans from Florida in the Late Oligocene revealed fossils attributed to Eleutherodactylus, providing evidence of their presence in North America before colonizing Central America. This study demonstrates the dispersal of amphibians from the Caribbean into North America during the Late Oligocene.

Large-bodied ornithomimosaurs inhabited Appalachia during the Late Cretaceous of North America

Chinzorig Tsogtbaatar, Thomas Cullen, George Phillips, Richard Rolke, Lindsay E. Zanno

Summary: Studying the evolution and diversity of Late Cretaceous dinosaur assemblages in North America requires continuous spatiotemporal data. However, there is a spatial and temporal disparity in the dinosaur data on the continent. This study describes an assemblage of ornithomimosaurian fossils from the Santonian Eutaw Formation in Mississippi. The results suggest the presence of two different-sized taxa, including one of the largest known ornithomimosaurians worldwide. These findings provide key information on the diversity and distribution of North American ornithomimosaurs and indicate the coexistence of multiple species of ornithomimosaurs in the Late Cretaceous ecosystems of Laurasia.

GMPE-consistent hard-rock site adjustment factors for Western North America

Linda Al Atik, Nicholas J. Gregor, Norman A. Abrahamson, Albert R. Kottke

Summary: Empirical ground-motion prediction equations (GMPEs) are limited in their ability to accurately predict ground motion in hard-rock conditions. The current state of practice involves the use of analytical methods or empirical factors to adjust the GMPEs. These methods have limitations, and a new methodology is proposed to develop linear site adjustment factors.

Summary: Intensifying macrovertebrate reconnaissance and age-dating techniques in recent decades have provided a more detailed understanding of the impact of the Cretaceous Thermal Maximum on terrestrial ecosystems. A new early-diverging ornithopod, Iani smithi gen. et sp. nov., has been discovered in Utah, USA, adding to the knowledge of Cretaceous fauna. This finding confirms the coexistence of at least five neornithischian clades in the earliest Late Cretaceous terrestrial ecosystems of North America.

A long-snouted and long-necked polycotylid plesiosaur from the Late Cretaceous of North America

Walter Scott Persons, Hallie P. Street, Amanda Kelley

Summary: Serpentisuchops pfisterae is an Upper Cretaceous plesiosaur with both elongated snout and elongated neck features. Its long snout is an ancestral trait, while its long neck is secondarily derived and similar to other related species. It has a piscivorous diet and likely used its neck and snout in fast lateral strikes.

Ecomorphospace occupation of large herbivorous dinosaurs from Late Jurassic through to Late Cretaceous time in North America

Taia Wyenberg-Henzler

Summary: After the Late Jurassic, there were significant changes in the megaherbivore communities in North America. The number of sauropods declined and became minor components of ecosystems, stegosaurs became extinct, and hadrosaurids, ceratopsids, and ankylosaurs increased in diversity and abundance. Previous studies dismissed the competitive replacement hypothesis of sauropods by hadrosauroids due to morphological differences, but this study found that there was overlap in ecomorphospace occupation between these two groups, suggesting that morphological differences were not enough to explain the niche partitioning. Further research is needed to determine the cause of the decline of sauropods and extinction of stegosaurs in North America.

The first evidence of Heosminthus from North America and the phylogenetics of Sminthidae (Mammalia, Rodentia, Dipodoidea): biogeographical implications

J. J. M. Calede, Y. T. Tse, K. D. Cairns

Summary: This study reports the first occurrence of a smooth-incisor sminthid from North America and provides evidence for a dispersal event of sminthid rodents from Eurasia to North America 30 million years ago via Beringia. The phylogenetic analysis shows a close relationship between the new species and Heosminthus borrae from Mongolia. The morphometric analysis suggests a terrestrial ecology for the new species.

Vegetation and fire history of Bwabwata National Park, Namibia

Adele C. M. Julier, Glynis J. Humphrey, Caitlin Dixon, Lindsey Gillson

Summary: The relationships between woody vegetation cover and fire, climate, herbivory, and human activities in African savanna ecosystems are complex. Fire suppression policies implemented in a national park in northeast Namibia from 1888 to 2005 did not lead to noticeable decreases in fire or enhanced tree recruitment, suggesting that fire occurrence in savanna ecosystems is more closely linked to climate than management. Fire management should adapt to rainfall variability and integrate customs of early dry season burning.
