[1] Noble gas temperatures (NGTs) and C derived ages in groundwaters of the Michigan Basin reveal a ground temperature of 1 C toward the end of the Last Glacial Maximum (LGM) suggesting that groundwater recharge occurred under the Laurentide Ice Sheet (LIS) cover. In addition to the general warming observed since the LGM, the NGT record indicates an abrupt warming event between 12.8 and 11.1kyr...

New material of the derived baenid turtle Boremys pulchra from Hell Creek Formation Montana extends stratigraphic range taxon through at minimum latest Maastrichtian. Previously, species was constrained to Campanian and Alberta, so this extension constitutes least 5 million years. Due fossil reworking Bug Anthills assemblage, where Maastrichtian Paleocene deposits are mixed, a definitive for B....
