“…The δ 18 O H2O values of meteoric water are controlled by fractionation processes during the atmospheric water cycle and water vapour transport, and, especially at mid-and high-latitudes, air temperature and humidity during precipitation are the major controlling factors (Dansgaard, 1964;Rozanski et al, 1993;Fricke and O'Neil, 1999). Bioapatite δ 18 O values of water-dependent, obligate drinking mammals record best meteoric water values and, hence, climatic conditions (Longinelli, 1984;Kohn, 1996;Levin et al, 2006).…”

Fossils of megaherbivores from eight late Pleistocene 14 C-and OSL-dated doline infillings of Ajoie (NW Switzerland) were discovered along the Transjurane highway in the Swiss Jura. Carbon and oxygen analyses of enamel were performed on forty-six teeth of large mammals (Equus germanicus, Mammuthus primigenius, Coelodonta antiquitatis, and Bison priscus), coming from one doline in Boncourt (~80 ka, marine oxygen isotope stage MIS5a) and seven in Courtedoux (51-27 ka, late MIS3), in order to reconstruct the paleoclimatic and paleoenvironmental conditions of the region. Similar enamel δ 13 C values for both periods, ranging from −14.5 to −9.2‰, indicate that the megaherbivores lived in a C 3 plant-dominated environment. Enamel δ 18 O PO4 values range from 10.9 to 16.3‰ with a mean of 13.5 ± 1.0‰ (n = 46). Mean air temperatures (MATs) were inferred using species-specific δ 18 O PO4 -δ 18 O H2O -calibrations for modern mammals and a present-day precipitation δ 18 O H2O -MAT relation for Switzerland. Similar average MATs of 6.6 ± 3.6°C for the deposits dated to~80 ka and 6.5 ± 3.3°C for those dated to the interval 51-27 ka were estimated. This suggests that these mammals in the Ajoie area lived in mild periods of the late Pleistocene with MATs only about 2.5°C lower than modern-day temperatures.

“…Oxygen isotope ratios in the tooth enamel of large mammals closely reflect the isotopic content of ingested water, consumed by drinking and through the intake of water in food (Longinelli, 1984;Luz et al, 1984;Bryant and Froelich, 1995;Kohn, 1996). Ingested waters are, in turn, primarily controlled by the isotopic content of local precipitation, which in continental environments is determined by near-surface air temperature (e.g.…”

Between 50,000 and 20,000 years ago, Europe experienced a series of rapid climate change events known as the Dansgaard-Oeschger cycles, which may have made areas of northern Europe more attractive for occupation by early modern humans at certain times than at others. This paper investigates when humans were occupying northern Europe in relation to these climatic changes at the archaeological site of Kraków Spadzista Street (B), by applying oxygen isotope analysis of mammoth tooth enamel carbonates (δ18O and δ13C) found at the site. The new isotopic data suggest that mean annual temperatures at Kraków Spadzista were 4-9oC colder than present and, based on comparisons with previously published isotopic data for mammoth in Europe, we argue that the Kraków assemblage most likely formed during a cold Dansgaard-Oeschger event. This suggests modern humans were able to occupy and survive in this area of northern Europe during the harsh cold phases that affected Europe at this time.

“…According to Zazzo et al (2004), this is important as it suggests that the 8 18 0C0 3 signal has not been modified. Interspecific differences in 8 18 0C03 values can also be interpreted from a palaeoecological point of view Kohn, 1996;Sponheimer and Lee-Thorp, 1999 …”

“…The 8 1 S0 value in both enamel phosphate and carbonate is related to that of body water, which in turn records water uptake (inspired O2, drinking water and plant water) and loss (excretion, expired CO2 and water vapour) of the animal during tooth development (Bryant and Froelich, 1995;Kohn, 1996). 8 1 S0 values can be interpreted as changes in the isotopic composition of meteoric water, which are in turn positively correlated to mean annual temperature and humidity.…”

“…Thus, an increase in temperature and aridity is associated with an enrichment of the heavy isotope eSO) whereas, a decrease in temperature and an increase in humidity result in a depletion of the heavy isotope (Luz et al, 1990;Ay liffe et al, 1992). 8 1 S0 values from herbivore tooth enamel may also provide information about the type of diet and the evaporative rate suffered by the consumed vegetation and hence, it is possible to differentiate between obligate drinkers (animals that obtain most of their water from drinking, frequently grazers fe eding on vegetation with heavier isotopic values due to higher evaporation) and non obligate drinkers (those obtaining water mainly from plants, fre quently browsers fe eding on vegetation with lighter isotopic values) (Kohn, 1996;Levin et al, 2006). The 8 1 S0 value of tooth enamel may also be affected by other factors such as the relative proximity to the coast, orography and latitude.…”
