"Isotopic Indications of Late Pleistocene and Holocene Paleoenvironment" by Jane Skippington, Tiina Manne et al.

Abstract
This paper presents the first application of mammal tooth enamel carbonate stable isotope analysis for the purpose of investigating late Pleistocene-early Holocene environmental change in an Australian archaeological context. Stable carbon (δ13C) and oxygen (δ18O) isotope ratios were analyzed from archaeological and modern spectacled hare wallaby (Lagorchestes conspicillatus) and hill kangaroo (Osphranter robustus) tooth enamel carbonates from Boodie Cave on Barrow Island in Western Australia. δ18O results track the dynamic paleoecological history at Boodie Cave including a clear shift towards increasing aridity preceding the onset of the Last Glacial Maximum and a period of increased humidity in the early to mid-Holocene. Enamel δ13C reflects divergent species feeding ecology and may imply a long-term shift toward increasing diversity in vegetation structure. This study contributes new data to the carbonate-isotope record for Australian fauna and demonstrates the ....

Britain may lose future 'Lindow Man' discoveries to damaged peat bogs, archaeologists warn

Britain may lose future Lindow Man discoveries to damaged peat bogs, archaeologists warn
Restoration projects to repair crucial peat bogs are becoming more common, but they don t always preserve archaeological heritage

Lindow Man is a national treasure admired by thousands at the British Museum.
But stunning “bog body” discoveries may become a thing of the past as peat decline destroys our archaeological heritage, archaeologists have warned.
Intact peat is a highly effective preservative, keeping items including wood, cloth and human remains in good condition for thousands of years. ....

Less wastage during production of marble slabs in the Roman imperial period than today

When it comes to ancient Roman imperial architecture, most people usually have a mental image of white marble statues, columns, or slabs. While it is true that many buildings and squares at that time were decorated with marble, it was frequently not white but colored marble that was employed, such as the green-veined Cipollino Verde, which was extracted on the Greek island of Euboea. Because marble was very expensive, it was often placed in thin slabs as a cladding over other, cheaper stones. To date, however, no actual remains of marble workshops from the Roman imperial era have been found, so little is known about marble processing during this period, said Professor Cees Passchier of the Institute of Geosciences at Johannes Gutenberg University Mainz (JGU). Together with other re ....
