Mammal remains preserved in the permafrost zone often bear traces of postmortem transformations, reflecting aspects palaeoenvironment and processes that took place during accumulation host sediments. Multidisciplinary studies including radiocarbon dating, infrared spectroscopy, microfossil analyses grain size infilling sediments from allow recognition their stratigraphical palaeogeographical or...

The Buxton-Norlim Limeworks southwest of Taung, South Africa, is renowned for the discovery of the first Australopithecus africanus fossil, the 'Taung Child'. The hominin was recovered from a distinctive pink calcrete that contains an abundance of invertebrate ichnofauna belonging to the Coprinisphaera ichnofacies. Here we describe the first fossil bee's nest, attributed to the ichnogenus Celli...

The latest Neoproterozoic extinction of the Ediacara biota has been variously attributed to catastrophic removal by perturbations to global geochemical cycles, 'biotic replacement' by Cambrian-type ecosystem engineers, and a taphonomic artefact. We perform the first critical test of the 'biotic replacement' hypothesis using combined palaeoecological and geochemical data collected from the young...
