Formation of the Isthmus of Panama
Independent evidence from rocks, fossils, and genes converge on a cohesive narrative of isthmus formation in the Pliocene. The formation of the Isthmus of Panama stands as one of the greatest naturalExpand

The Magnitude and Duration of Late Ordovician–Early Silurian Glaciation
Carbonate isotopes reveal a link between past ocean temperatures and mass extinction. Understanding ancient climate changes is hampered by the inability to disentangle trends in ocean temperatureExpand

CARBONATES IN SKELETON-POOR SEAS: NEW INSIGHTS FROM CAMBRIAN AND ORDOVICIAN STRATA OF LAURENTIA
Abstract Calcareous skeletons evolved as part of the greater Ediacaran–Cambrian diversification of marine animals. Skeletons did not become permanent, globally important sources of carbonateExpand

Climate change and the selective signature of the Late Ordovician mass extinction
Selectivity patterns provide insights into the causes of ancient extinction events. The Late Ordovician mass extinction was related to Gondwanan glaciation; however, it is still unclear whetherExpand

  • Proceedings of the National Academy of Sciences
  • 19 June 2007
Wide geographic range is generally thought to buffer taxa against extinction, but the strength of this effect has not been investigated for the great majority of the fossil record. Although theExpand

  • Biology, Medicine
  • Proceedings of the National Academy of Sciences
  • 6 January 2009
The maximum size of organisms has increased enormously since the initial appearance of life >3.5 billion years ago (Gya), but the pattern and timing of this size increase is poorly known.Expand

Climate Change and the Past, Present, and Future of Biotic Interactions
Biotic interactions drive key ecological and evolutionary processes and mediate ecosystem responses to climate change. The direction, frequency, and intensity of biotic interactions can in turn beExpand

A signature of transience in bedrock river incision rates over timescales of 104–107 years
Measured rates of river incision into bedrock are commonly interpreted as proxies for rates of rock uplift (see refs 1 and 2, for example) and indices of the strength of climatic forcing of erosionExpand

The Red Queen revisited: reevaluating the age selectivity of Phanerozoic marine genus extinctions
Abstract Extinction risk is inversely related to genus age (time since first appearance) in most intervals of the Phanerozoic marine fossil record, in apparent contradiction to the macroevolutionaryExpand

Records of carbon and sulfur cycling during the Silurian Ireviken Event in Gotland, Sweden
Abstract Early Silurian (∼431 Ma) carbonate rocks record a ca. 4.5‰ positive excursion in the stable isotopic composition of carbonate carbon (δ13Ccarb). Associated with this isotopic shift is aExpand
