“…This is in broad agreement with the dataset of Korte et al (2015) for the Early Jurassic, which shows mostly higher δ 13 C values in bivalves than in brachiopods of the same age. Other studies, however, show that co-occurring bivalves and brachiopods have very similar δ 13 C values (e.g., Alberti et al 2017Alberti et al , 2019. Further data of different faunal groups is therefore necessary to judge whether there actually is a trend in the δ 13 C values through time or whether the difference is merely caused by vital effects.…”

“…Such a correlation should therefore be treated with caution, although in some cases it can be primary in origin, for example, because of an increase in primary productivity with higher water temperatures.

“…This can be attributed to a higher palaeolatitude of the European localities in the northern hemisphere compared to Chile in the southern hemisphere. At the same time, it has to be noted that the majority of data from Europe is based on belemnites, which are known to commonly record lower temperatures than co-occurring brachiopods and bivalves (e.g., Dera et al 2011;Alberti et al 2012aAlberti et al , 2019. The cause of this difference might include different life habits between the faunal groups, but is still strongly debated in literature (Fürsich et al 2005;Mutterlose et al 2010;Alberti et al 2012aAlberti et al , 2012bPrice et al 2015;Dera et al 2016;Hoffmann et al 2016).…”

“…In the last few decades, this simple view has been challenged by a series of articles, suggesting polar ice caps for at least short intervals in the Jurassic (e.g., Price 1999;Dromart et al 2003;Suan et al 2008Suan et al , 2010 and larger temperature fluctuations (e.g., Dera et al 2011;Korte et al 2015;Martinez and Dera 2015;Silva and Duarte 2015;Price et al 2016). Only recently, Alberti et al (2017Alberti et al ( , 2019 presented data pointing to latitudinal temperature gradients in the Middle and Late Jurassic as steep as today. Much of our knowledge on the Jurassic climate is based on seawater temperature reconstructions using stable isotope (δ 18 O) analyses of fossil hard parts.…”

“…Consequently, it seems beneficial to gather more information from non-European sections in order to fully understand global climate conditions in the Jurassic. The present study is part of a series of articles trying to improve our knowledge of the seawater temperature conditions of Gondwanan localities (Alberti et al 2012a(Alberti et al , 2012b(Alberti et al , 2013(Alberti et al , 2017(Alberti et al , 2019.…”

The stable isotope (δ 13 C, δ 18 O) composition of a collection of Lower Jurassic brachiopods and oysters from the Andean Basin of northern Chile was analyzed. The results allow the first reconstruction of absolute water temperatures for several ammonite zones in the Lower Jurassic of South America. The temperature record starts with comparatively high values in the Late Sinemurian (average: 27.0°C; Raricostatum Zone). Just before the Sinemurian-Pliensbachian transition, temperatures dropped to an average of 24.3°C. The lowest temperature value in the dataset was recorded for a brachiopod shell of the latest Pliensbachian Spinatum Zone (19.6°C). No data are available for the Early Toarcian, but results for the late Toarcian show again comparatively warm conditions (average: 24.4°C; Thouarsense-Levesquei zones). Even though more material and analyses are necessary to corroborate the recorded temperatures, the present dataset seems to indicate the global nature of the Late Pliensbachian Cooling Event. In contrast, the global warming during the Toarcian Oceanic Anoxic Event has not been recorded due to a lack of Early Toarcian material. The δ 13 C record of brachiopods and oysters documents a gradual increase in values representing background conditions. Oyster shells were used for high-resolution stable isotope analyses and show seasonal temperature fluctuations over a period of around 3 years in the life time of the bivalves. If explained only by temperatures, the δ 18 O values point to a minimum estimate for the seasonality in the late Toarcian of slightly more than 3°C.

We review palaeoenvironmental applications of stable isotope analysis to Late Pleistocene archaeological sites across Southeast Asia (SEA), a region critical to understanding the evolution of Homo sapiens and other co-existing Late Pleistocene (124–11.7 ka) hominins. Stable isotope techniques applied to archaeological deposits offer the potential to develop robust palaeoenvironmental reconstructions, to contextualise the occupational and non-occupational history of a site. By evaluating the published research in this field, we show that sediments, guano, tooth enamel, speleothem and biomolecular material such as leaf waxes have great potential to provide site-specific palaeoenvironmental records and local and catchment-scale landscape context to hominin dispersal in the region. However, stable isotope techniques used in these contexts are in their infancy in SEA, and the diagenetic controls associated with hot and humid environments that typify the region are not yet fully understood. Additionally, availability of sources of stable isotopes varies between sites. Nonetheless, even the limited research currently available shows that stable isotope analyses can aid in developing a better understanding of the role of the environment on the nature and timing of dispersals of our species eastwards into SEA and beyond.
