* Hagstrum ''et al.'' (2017) report impact-related microspherules and elevated platinum concentrations found in fine-grained sediments retained within Late Pleistocene bison and mammoth skull fragments from Alaska and Yukon, and interpret the findings as evidence of repeated airbursts and ground/ice impacts associated with multiple episodes of cosmic impact.
* A study on changes in landscape moisture in the rangelands in Europe, Siberia and the Americas during the late Pleistocene as indicated by data from the bones of megaherbivores is published by Rabanus-Wallace ''et al.'' (2017).
