Ceratopsids ("horned dinosaurs") are known from western North America and Asia, a distribution reflecting an inferred subaerial link between the two landmasses during the Late Cretaceous. However, this clade was previously unknown from eastern North America, presumably due to limited outcrop of the appropriate age and depositional environment as well as the separation of eastern and western Nor...

Source scaling relations have been obtained for earthquakes in eastern North America and other co'ntinental interiors, and compared with a relation obtained for earthquakes in western North America. The scaling relation for eastern North American earthquakes was constructed from measurements of seismic moment and source duration obtained by the waveform modeling of seismic body waves. The event...

The arrival of bison in North America marks one of the most successful large-mammal dispersals from Asia within the last million years, yet the timing and nature of this event remain poorly determined. Here, we used a combined paleontological and paleogenomic approach to provide a robust timeline for the entry and subsequent evolution of bison within North America. We characterized two fossil-r...

The history of research in North America suggests that we already know when people arrived in the continental US: about 11,500 C yr BP. Research also suggests that people were in the southern cone of South America by a comparable age, if not earlier. If the New World was colonized by Late Pleistocene migrants from Asia via the Bering Strait, then the earliest sites should be in North not South ...
