DOI: 10.1016/j.earscirev.2018.02.012
Abstract: Abstract The Cretaceous/Paleogene (K/Pg) boundary is well-represented across a range of depositional settings in New Zealand. Trends in fossil assemblages and marine lithofacies indicate that the K/Pg event was followed by a pronounced and long-term… read more here.

DOI: 10.1016/j.jafrearsci.2020.103779
Abstract: Abstract During the Late Cretaceous-Paleogene time, a widespread sedimentary organic-rich succession developed throughout the middle latitudes of Egypt. Since the study area conserves the organic-rich intervals three shallow boreholes were drilled through the Upper Cretaceous-Paleogene… read more here.

DOI: 10.1016/j.lithos.2020.105835
Abstract: Abstract Late Cretaceous felsic and latest Cretaceous-Paleogene basaltic volcanic rocks are exposed throughout the Kyrenia Range, N Cyprus. Field mapping of the key, well-exposed western range indicates that the felsic volcanics are mainly crop out… read more here.

DOI: 10.1016/j.palaeo.2020.110081
Abstract: Abstract Changes in terrestrial environments across the Cretaceous-Paleogene boundary, including plant ecology and carbon and water-cycling, remain poorly defined. Fluvial sediments spanning the Cretaceous-Paleogene (K-Pg) boundary of southern Saskatchewan, Canada contain well preserved plant wax… read more here.

DOI: 10.1029/2019gl085572
Abstract: Prolonged periods of low light and cold temperatures at Earth's surface are hypothesized effects of the end‐Cretaceous asteroid impact. However, debate remains about the causes and consequences of this “impact winter.” We perform simulations of… read more here.
