On late miocene abyssal hydrography
Marine Micropaleontology, 1981Abstract This contribution is a summary of our studies on late Miocene isotope stratigraphy. We interpret the results using simple models and present additional evidence that the δ 13 C shift at 6.2 Ma was a time-stratigraphic event. The average deep-water metabolic CO 2 and nutrient content remained unchanged across the δ 13 C shift, but the net ...

Phylogenetic analysis of Middle-Late Miocene apes
Journal of Human Evolution, 2022Despite intensive study, many aspects of the evolutionary history of great apes and humans (Hominidae) are not well understood. In particular, the phylogenetic relationships of many fossil taxa remain poorly resolved. This study aims to provide an updated hypothesis of phylogenetic relationships for Middle-Late Miocene fossil apes, focusing on those ...

Hominin locomotion and evolution in the Late Miocene to Late Pliocene
Journal of Human Evolution, 2023In this review, we present on the evolution of the locomotor adaptation of hominins in the Late Miocene to Late Pliocene, with emphasis on some of the prominent advances and debates that have occurred over the past fifty years. We start with the challenging issue of defining hominin locomotor grades that are currently used liberally and offer our own ...

Bone Smashing by Late Miocene Hominidae
Nature, 1968Bones found in the Upper Miocene Fossil Beds of Fort Ternan, Kenya, show evidence of having been broken up by some kind of blunt instrument.

Late Oligocene–early Miocene transformation of postcollisional magmatism in Tibet
Geology, 2019Uplift of the Tibetan Plateau is thought to be one of the most important orogenic and climate forcing events of the Cenozoic Era, associated with geodynamic changes related to India-Asia collision and subsequent continental lithosphere subduction ...

ASTROCHRONOLOGY OF LATE MIDDLE MIOCENE MEDITERRANEAN SECTIONS
2004High-resolution cyclostratigraphy and calcareous plankton astrobiochronology have been obtained from the latest Langhian to the earliest Tortonian of the Mediterranean. The investigated areas (Malta, Tremiti, and Sicily) are located in different geological settings, and the three studied sections show different cyclicity. Direct correlation between the

Late Miocene drying of central Australia
Palaeogeography, Palaeoclimatology, Palaeoecology, 2019Abstract A back to the future approach to climate change refines Neogene records of paleoclimatic cooling and drying as future climate states for a warming world. Near Alcoota station in central Australia is a late Miocene fossil mammal site for Alcoota (10 Ma) and Ongeva (8 Ma) local faunas.

Late Miocene “washhouse” climate in Europe
Earth and Planetary Science Letters, 2008Abstract We present two eight-million year long proxy records of precipitation for Southwest and Central Europe, covering the middle to late Miocene (5.3–13 Ma) at a temporal resolution of about 60 kyr and 150 kyr, respectively. The estimates of precipitation are based on the ecophysiological structure of herpetological assemblages (amphibians and ...

Middle Miocene (∼14 Ma) and Late Miocene (∼6 Ma) Paleogeographic Boundary Conditions
Paleoceanography and Paleoclimatology, 2021AbstractDuring the Miocene, major global cooling occurred during two intervals: the middle Miocene (∼14–13 Ma) and the late Miocene (∼7‐6 Ma). The Antarctic Ice Sheet expanded substantially at ∼14–13 Ma, and glaciation in the Northern Hemisphere was initiated at ∼7–6 Ma.
