The fossil record stays silent: Confusions and conundrums for hominin pelvis evolution

The Anatomical Record, EarlyView.
Abstract The evolution of the hominin pelvis is commonly modeled as a series of stages driven largely by the requirements of bipedal locomotion, reproduction, thermoregulation, and pelvic floor muscular support. These patterns are complicated by variation in canal dimensions in relationship with different changes in overall pelvic breadths. To quantify

Towards a radiocarbon calibration for oxygen isotope stage 3 using New Zealand kauri (Agathis australis) [PDF]

, 2007
It is well known that radiocarbon years do not directly equate to calendar time. As a result, considerable effort has been devoted to generating a decadally resolved calibration curve for the Holocene and latter part of the last termination.

Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

Journal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.

Purification of hydroxyproline for small-scale radiocarbon dating verified using archaeological bone collagen

Progress in Earth and Planetary Science
We developed a novel technique for the accurate radiocarbon dating of single amino acids from archaeological human and animal remains. Despite the extensive use of bulk collagen for radiocarbon dating of archaeological bones, obtaining accurate dates can
