Taung and beyond: The mining history, geology and taphonomy of Australopithecus in South Africa
South African Journal of ScienceSouth Africa is host to the single richest early hominin fossil record worldwide, including many examples of the endemic species Australopithecus africanus fossils. This species was first described by Raymond Dart in 1925 from the deposits near the town

Boreas, EarlyView.Glacial erosion during the Last Glacial Maximum (LGM) has removed much evidence of earlier glaciations and interglacials in the European Alps. At Gröbminger Mitterberg (GM), beneath a blanket of LGM till, a distinctive sediment archive preserves deposits predating the LGM.

High-temperature environments of human evolution in East Africa based on bond ordering in paleosol carbonates [PDF]
, 2010 Many important hominid-bearing fossil localities in East Africa are in regions that are extremely hot and dry. Although humans are well adapted to such conditions, it has been inferred that East African environments were cooler or more wooded during the ...

Boreas, EarlyView.The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

The Economic History Review, EarlyView.Abstract The 1430s were characterized by extreme weather conditions, food and fodder shortages, and high mortalities among animals and humans, although the severity of events and their consequences in England have received limited attention. The economic downturn and the depressed customary land market in this decade marked the beginning of the Great ...

Episodic speleothem deposition tracks the terrestrial impact of millennial-scale last glacial climate variability in SW Ireland [PDF]
, 2016 Eighty four new U-Th ages are presented for twenty randomly selected broken, displaced and reworked calcite speleothems retrieved from clastic sedimentary fill and from isolated bedding-plane shelves in Crag cave (SW Ireland).

Bio‐mediated cementation of supratidal beach sediments associated with groundwater springs
Sedimentology, EarlyView.ABSTRACT The formation of beachrock, sensu stricto, via carbonate precipitation in the intertidal zone is widespread throughout the tropics and subtropics. While cementation of supratidal beach sediments has also been noted in several locations, it has received much less attention.

Extracting winter North Atlantic Oscillation information from a central European stalagmite [PDF]
, 2013 This study explores the potential for extracting winter North Atlantic Oscillation (NAO) information from central European stalagmites using a high resolution calcite δ18O (δ18Ocal) time-series from a stalagmite (AH1) extracted from Atta cave in ...
