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

    Xiaoming Wang et al.
    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.

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

    Fidelis T Masao et al.
    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..

    The complex of TRIP-Br1 and XIAP ubiquitinates and degrades multiple adenylyl cyclase isoforms

    Wenbao Hu et al.
    XIAP/TRIP-Br1-mediated degradation of multiple adenylyl cyclase isoforms is a previously unrecognised general mechanism for controlling adenylyl cyclase expression and the homeostasis of cAMP signalling.

    Homo naledi and Pleistocene hominin evolution in subequatorial Africa

    Lee R Berger et al.
    A late Middle Pleistocene age for Homo naledi demonstrates a diversity of hominin species in Africa at this critical time in the archaeological record.

    Preservation of three-dimensional anatomy in phosphatized fossil arthropods enriches evolutionary inference

    Achim H Schwermann et al.
    X-ray imaging reveals well-preserved internal characters in mineralized arthropods from the Paleogene, urging the reexamination of previously neglected fossil collections.

    Geological and taphonomic context for the new hominin species Homo naledi from the Dinaledi Chamber, South Africa

    Paul HGM Dirks et al.
    A new hominin species found in a South African cave is part of one of the most unusual hominin fossil assemblages on record.

    Protein sequences bound to mineral surfaces persist into deep time

    Beatrice Demarchi et al.
    A chemically unstable ostrich eggshell peptide survives for at least 3.8 million years at the equator, stabilized by strong mineral interactions.

    Palaeogenomes of Eurasian straight-tusked elephants challenge the current view of elephant evolution

    Matthias Meyer et al.
    DNA sequences from the Middle Pleistocene reveal that the extinct Eurasian straight-tusked elephants were closely related to today's African forest elephants (Loxodonta cyclotis) in Africa.
