Tooth eruption and wear, crown height, manual optical analysis of dental cementum, line histogram analysis of dental cementum, and a new automated digital technique for analysing dental cementum are employed. Unfortunately, cementum analysis is not utilised more often because it is time consuming, expensive, destructive, and requires a high degree of technological proficiency and observer training for accurate and consistent results.Each tooth was measured, thin-sectioned, digitally photographed under microscopy, and the cementum layers analysed. Estimating the Age- and Season-of-Death for Wild Equids: a Comparison of Techniques Utilising a Sample from the Late Neolithic Site of Bad Buchau-Dullenried, Germany. In recent years, advances in digital and computer automation technology have enabled the introduction of a new automated digital approach to cementum analysis ().NORTONVILLE AND 6 MILES SOUTHEAST OF MORTONS GAP BY 1205 PM CDT...

This hypothesis is based on the inferred correlation between climatic deterioration, concurrent lowering of lightning-ignited fire frequencies, and reduced signals for fire use in layers presumably deposited during the Lower Pleniglacial (Marine Isotope Stage 4) at the Middle Palaeolithic sites of Roc de Marsal and Pech de l’Azé IV (Aquitaine Basin, southwestern France), the logic being that if Neandertals could produce fire at will, fire use signals would remain largely consistent throughout the deposits despite there being limited access to natural fires in the landscape during this colder period.This review challenges these assertions at multiple scales by looking at regional lightning and fire regime dynamics, comparing the fire signals observed at Roc de Marsal and Pech de l’Azé IV to those of other sites nearby and around France, and exploring the various environmental and cultural factors likely influencing these signals.Colonizing populations remained low – perhaps two orders of magnitude below those estimated at European contact – for many millennia, and were long restricted to relatively favorable habitats.Though human arrival coincided with changes in native flora and fauna, these were mainly the products of climatic factors, not human interference.
With this in mind, the research presented in this article weighs in on the debate concerning Neandertal fire use and fire making, specifically, the assertion that Neandertals were unable to produce fire for themselves (Sandgathe et al., 2011a, 2011b).

The results demonstrate that the digital automated technique has an advantage over conventional cementum increment counting in terms of reduced subjectivity, efficiency and accuracy for the identification of season- and age-of-death. It allows fossil (palaeontological and zooarchaeological) specimens with poorly preserved dentition to be more systematically analysed despite their diagenetic deficiencies (i.e., structural damage from the burial environment). In contrast, tooth eruption, wear and crown height have been widely recognised to be more accurate indicators of age-at-death.
Inaccurate and/or subjective observations and measurements can be circumvented with the use of computer analysis and quality thin-section preparation.
