Evidence for Pleistocene gene flow through the ice-free corridor from extinct horses and camels from Natural Trap Cave, Wyoming

Kieren J. Mitchell et al.

Summary: Natural Trap Cave in Wyoming has preserved an abundance of fossil remains from extinct Late Pleistocene fauna, indicating a past migration route between Eastern Beringia and the contiguous US. A genetic analysis of horse and camel specimens from the cave suggests a higher affinity with Eastern Beringian individuals, supporting the hypothesis of genetic connectivity between the Bighorn Mountains and Eastern Beringia during the Pleistocene.

Paleo-vegetation and environmental history of Natural Trap Cave based on pollen and carbon isotope analyses

Thomas A. Minckley et al.

Summary: Pollen and carbon isotope data from Natural Trap Cave provide insights into the environmental conditions of the Bighorn Basin in Wyoming, USA during different time intervals. The data indicate steppe-like, cold-dry conditions during the glacial maxima with abundant Artemisia, Amaranthaceae, Asteraceae, and Poaceae pollen. There are indications of relatively wet summers during certain periods. The Holocene shows greater arboreal pollen abundance and more humid conditions compared to the late Pleistocene glacial conditions, with a distinct chemostratigraphic marker at the Pleistocene-Holocene boundary.

The rank abundance distribution of large-bodied vertebrates from Natural Trap Cave, Wyoming

Cory M. Redman et al.

Summary: This study examines the stability of the local ecosystem surrounding Natural Trap Cave across the Late Pleistocene-Holocene transition by analyzing the rank abundance distribution of large-bodied vertebrates. The results show that the ecosystem composition and structure remained relatively stable, with a few dominant taxa. Rating: 7 out of 10.

Natural Trap Cave tephra correlation to Yellowstone using U-series (230Th/238U) dates and oxygen isotopes of zircon and chemical composition of adherent glass

Axel K. Schmitt et al.

Summary: Zircon crystals from Natural Trap Cave (NTC) in Wyoming were studied to refine the chronostratigraphy of the late-Quaternary megafaunal assemblage. The analysis of glass compositions and oxygen isotopes of the zircon crystals revealed their provenance from post-Lava Creek Tuff activity of Yellowstone. The NTC tephra record has the potential to refine the volcanic history and distribution patterns of Yellowstone during the late Pleistocene.

Luminescence ages and new interpretations of the timing and deposition of Quaternary sediments at Natural Trap Cave, Wyoming

Shannon Mahan et al.

Summary: Natural Trap Cave in Wyoming has trapped and preserved a variety of North American fauna, providing insights into faunal dynamics and ecological changes in North America. Excavation work in 2014 and 2018, along with various dating techniques, has helped improve the chronological age model of the cave sediments and understand the deposition process. The cave deposits indicate episodic and rapid sedimentation, followed by periods of stability and possible hydrologic or cryo-hydrologic processes.

Were pronghorns (Antilocapra) primary prey for North American cheetahs (Miracinonyx)?

Pennilyn Higgins et al.

Summary: The predator-prey relationship between Pronghorn and Miracinonyx was tested using isotopic analysis of bone collagen from Natural Trap Cave. The results support the hypothesis that Miracinonyx preyed upon Antilocapra, but not exclusively. Antilocapra was also important prey for lions and wolves, with wolves showing a preference for horses.

Late Pleistocene environments of the Bighorn Basin, Wyoming-Montana, USA

Thomas A. Minckley et al.

Summary: Limited high-resolution records prior to the Last Glacial Maximum make it difficult to quantify environmental impacts before peak glaciation. However, analysis of sediments from Last Canyon Cave in the Pryor Mountains revealed significant changes in pollen and stable isotope values, indicating cooler and seasonally wetter conditions before the LGM, followed by post-glacial warming and a drop in delta C-13 values at the onset of the Younger Dryas.

Caught in a bottleneck: Habitat loss for woolly mammoths in central North America and the ice-free corridor during the last deglaciation

Yue Wang et al.

Summary: This study investigated the role of the ice-free corridor in North America during the late Quaternary megafaunal extinctions, finding limited suitability for mammoths and quick reforestation after opening. It also suggests declining habitat suitability in central North America due to rapid reforestation and decreased forage productivity. Declining habitat availability and limited corridor suitability were contributing factors in North American extinctions of woolly mammoths and other large grazers, highlighting the importance of protected habitat connectivity during changing climates for large vertebrates.

Dire wolves were the last of an ancient New World canid lineage

Angela R. Perri et al.

Summary: Dire wolves, common in Pleistocene America, were found to have diverged from living canids around 5.7 million years ago and evolved in isolation from ancestors of grey wolves and coyotes. There is no evidence of gene flow between dire wolves and North American grey wolves or coyotes, indicating a distinct evolutionary history. Our results also support an early New World origin of dire wolves compared to the Eurasian ancestors of other canids.
