    First bone-cracking dog coprolites provide new insight into bone consumption in Borophagus and their unique ecological niche

    Xiaoming Wang, Stuart C White ... Z Jack Tseng
    Fossilized feces (coprolites) of extinct bone-crushing dogs, Borophagus parvus, from late Miocene (6 million years ago) of California demonstrates consumption and preservation of bones in digestive tracts and potential social hunting behavior by these predators.

    A new genus of horse from Pleistocene North America

    Peter D Heintzman, Grant D Zazula ... Beth Shapiro
    The extinct stilt-legged equids of North America are not related to Asiatic asses or horses, but instead represent a distinct lineage outside of living equid diversity that became extinct in the terminal Pleistocene.

    New footprints from Laetoli (Tanzania) provide evidence for marked body size variation in early hominins

    Fidelis T Masao, Elgidius B Ichumbaki ... Giorgio Manzi
    Bipedal footprints made 3.66 million years ago provide the clearest available evidence to date of the occurrence of marked body size variation in Australopithecus afarensis..

    Diversification dynamics in the Neotropics through time, clades, and biogeographic regions

    Andrea S Meseguer, Alice Michel ... Fabien L Condamine
    Neotropical outstanding biodiversity emerged from sustained rates of species accumulation over time, although, for some periods, tetrapods were less successful than plants in keeping pace with a changing environment.

    Giant extinct caiman breaks constraint on the axial skeleton of extant crocodylians

    Torsten M Scheyer, John R Hutchinson ... Marcelo R Sánchez-Villagra
    The giant caiman Purussaurus from the Miocene of Venezuela is the first recorded member of crown Crocodylia having three sacrals, thus breaking the otherwise strict vertebral constraint of the group.
