N1 - Funding Information:
Rodolfo Coccioni (Urbino) and Fabrizio Lirer (Parma) are thanked for their help in the separation and identification of most of the foraminiferal tests. Bernd Bodiselitsch (Vienna) is thanked for the support during the mass spectrometric analyses. We thank Rich Muller and Jonathan Levine (Berkeley) for getting us started in spectral analysis, and Frits Hilgen (Amsterdam) for his ongoing cooperation on this subject. We thank Finn Surlyk, Mark Sephton, and an anonymous reviewer for thoughtful comments that led to an improved manuscript. The University of Vienna provided partial financial support to Dieter Mader. Laboratory work in Vienna was supported by the Austrian Science Foundation (grant Y58-GEO, to C. Koeberl). This work was also supported by the Coldigioco Research Fund and funds from Carleton College. The cyclostratigraphic record of the Monte dei Corvi succession, including the La Vedova section, has been translated into music by Rosetti and Montanari (2004) in their CD “Dances with the Earth”.

N2 - A high-resolution analysis of multiple climate proxies from a rhythmic mid-Langhian pelagic limestone - marl succession (northeastern Apennines of Italy) yields information on the pacing and nature of palaeoenvironmental changes in this part of the mid-Miocene Mediterranean. The variations in stable isotopes, magnetic susceptibility, and a variety of geochemical parameters through the section, although modified by diagenetic changes, are broadly consistent with a model of climate cycles in which the limestones represent cold/dry periods and the marls represent warm/wet periods. Fourier analysis of the multiple proxies, constrained by radioisotopic dates, and aided by partial tuning to either eccentricity or obliquity show that these proxies respond in synchrony to orbitally forced climate changes, with obliquity being the dominant influence in this succession.
