  1. Zircon U-Pb Geochronology Links the End-Triassic Extinction with the Central Atlantic Magmatic Province.

    Science (2013) PMID 23519213

    We present new zircon U-Pb geochronologic constraints on the age and duration of flood basalt volcanism within the Central Atlantic Magmatic Province. This chronology demonstrates synchroneity between the earliest volcanism and extinction, tests and corroborates the existing astrochronologic time sc...
  2. Melanin concentration gradients in modern and fossil feathers.

    PLoS One 8(3):e59451 (2013) PMID 23555675

    We evaluated 321 modern samples from 18 orders within Aves. We observed that the pattern was found most frequently in distantly related groups that share aquatic ecologies (e.g. waterfowl Anseriformes, penguins Sphenisciformes), suggesting a potential adaptive function with ancient origins....
  3. Crocodile head scales are not developmental units but emerge from physical cracking.

    Science 339(6115):78-81 (2013) PMID 23196908

    We show that contrary to skin appendages in other amniotes (as well as body scales in crocodiles), face and jaws scales of crocodiles are random polygonal domains of highly keratinized skin, rather than genetically controlled elements, and emerge from a physical self-organizing stochastic process di...
