Engelswies is an early Miocene vertebrate locality in southern Germany with a rich assemblage of terrestrial mammals, invertebrates and fossil plants. It is dated to 16.5-17.0 Ma based on magnetostratigraphy, biostratigraphy and lithostratigraphy, and includes among the faunal remains a hominoid upper molar fragment, the oldest hominoid so far identified from Europe. The evidence from Engelswie...

The Ediacaran Global Stratotype Section and Point has now been defined at the base of the Nuccaleena Formation in the Flinders Ranges National Park, South Australia. This GSSP marks the end of a major glacial epoch. In the absence of definitive biozones marking the base of the Ediacaran, the utility of this “cap carbonate’ for correlation will depend on the verification of a global fingerprint ...

Global synchronization of environmental change in terrestrial successions deep time is challenging owing to the paucity dating methods, a case also applicable Middle Upper Triassic Mercia Mudstone Group Britain. Using coastal cliff sections, magnetostratigraphy was evaluated at 263 horizons, defining 53 magnetozones. Magnetozones from lower 140 m group demonstrate correspondence those mid-Ladin...
