Insights into the Middle–Late Miocene palaeoceanographic development of Cyprus (eastern Mediterranean) from a new δ¹⁸O and δ¹³C stable isotope composite record [PDF]

Climate of the Past
The Middle to Late Miocene was a time of significant global climate change. In the eastern Mediterranean region, these climatic changes coincided with important tectonic events, which resulted in changes to the organisation of oceanic gateways, altering ...

Seismic stratigraphy and development of a modern isolated carbonate platform (Xuande Atoll) in the South China Sea

Frontiers in Earth Science, 2023
Xuande Atoll is an isolated carbonate platform that has developed since the early Miocene. This study conducted high-resolution seismic surveys and shallow drilling to understand its internal structure and development.

A New Late Miocene Odobenid (Mammalia: Carnivora) from Hokkaido, Japan Suggests Rapid Diversification of Basal Miocene Odobenids. [PDF]

PLoS ONE, 2015
The modern walrus, Odobenus rosmarus, is specialized and only extant member of the family Odobenidae. They were much more diversified in the past, and at least 16 genera and 20 species of fossil walruses have been known.

Late Miocene to late Pleistocene geomagnetic secular variation at high northern latitudes [PDF]

Geophysical Journal International, 2020
SUMMARYWe report a palaeomagnetic study of Icelandic lavas of late Miocene to late Pliocene age to test the geocentric axial dipole hypothesis at high northern latitudes. Cores were sampled from 125 sites in the Fljótsdalur valley in eastern Iceland, and hand samples were taken for 17 new incremental heating 40Ar/39Ar age determinations. 96 per cent of

The relationship between form and function of the carnivore mandible

The Anatomical Record, EarlyView.
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

Contribution of the late Miocene mammals from Calabria and Sicily to the palaeogeography of the central Mediterranean

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2019
During Miocene, the paleogeography of the central Mediterranean area underwent significant modifications under control of Plate Tectonics. The area here considered occupies a southern position, rougly coincident with the Calabria-Peloritan Arc (CPA ...

Pliocene expansion of C₄ vegetation in the Core Monsoon Zone on the Indian Peninsula [PDF]

Climate of the Past, 2020
The expansion of C4 vegetation during the Neogene was one of the largest reorganizations of Earth's terrestrial biome. Once thought to be globally synchronous in the late Miocene, site-specific studies have revealed differences in the timing of the ...
