“…Previous work on Several studies have been carried out with a view to optimizing the extraction of radiogenic isotopes (Nd, Sr) from various biogenic materials derived from the North Alpine Foreland Basin (Vennemann & Hegner 1998, Vennemann et al 2001, Janz & Vennemann 2005, Pippèrr et al 2007, Kocsis et al 2009) (see Figs 1, 3). Janz & Vennemann (2005) analysed the Sr isotopic composition of ostracods from two locations (Maierhof and Neuhofen) not far from Mitterdorf, the site studied here (see Fig.…”

“…-Nine well-preserved otoliths of both Diaphus and Coelorinchus were selected using the light orange colour and shiny gloss of the otoliths as indicators for unaltered material (see Pippèrr et al 2007). To check whether the Sr isotope signal is consistent within the otolith samples, both intact and fragmented otoliths were analysed ( Table 1).…”

“…Age reconstructions based on Sr isotope ratios in the NAFB have relied mainly on fish teeth (Vennemann & Hegner 1998, Vennemann et al 2001, Kocsis et al 2009), although the technique has also been applied to ostracods (Janz & Vennemann 2005) and otoliths (Pippèrr et al 2007). The Sr isotope data obtained in these studies are not always easy to interpret because some reveal a significant offset with respect to the global seawater Sr evolution curve due to e.g.…”

Precise age constraints are rare for the Oligocene to Miocene sediments in the North Alpine Foreland Basin, also referred to as Molasse Basin. This is mainly due to the lack of index fossils, absence of continuous outcrops and scarcity of radiometrically datable rocks. In this study, we applied the Sr isotope dating technique to fossil teleost fish otoliths to determine absolute ages for Lower Miocene (mid-Burdigalian, lower Ottnangian) marine sediments. The fossil otoliths from the marine genera Diaphus and Coelorinchus used in our analysis were recovered from the Neuhofen Beds in the SE German Molasse Basin. For the first time, leaching experiments were conducted on different otolith fractions to extract the ambient 87 Sr/ 86 Sr seawater signal. Based on the latest version of the evolution curve for the 87 Sr/ 86 Sr ratio in the global ocean, our new data suggest an age of 17.1 ± 0.3 Ma, which is at least 0.6 m.y. younger than hitherto assumed for the Neuhofen Beds based on biostratigraphy and lithostratigraphic correlations. We suggest that strong riverine inputs could account for this shift in the Sr isotope signal to younger ages. •
