In situ [sup.87]Sr/[sup.86]Sr analysis is presented in three case studies which deal with the following: (i) plagioclase crystals from Nisyros volcano (Greece), (ii) glassy matrix of single glassy clasts from the 2010 eruption of the Eyjafjallajokull volcano (Iceland), and (iii) bones and teeth from fossil remains of the Ursus spelaeus. In these three examples, the in situ Sr-isotope approach permits to constrain petrological and volcanological processes and to effectively outline the life habits and habitat exploitation of extinct living species.
Ursus spelaeus was an endemic, widespread European Late Pleistocene species.
We report here the first [sup.87]Sr/[sup.86]Sr data obtained through in situ microsampling on teeth and bones of Ursus spelaeus found in Grotta all'Onda cave.
The fossil remains of Ursus spelaeus were recovered during a 1999 excavation.
The enamel isotopic values obtained during our study indicate that Ursus spelaeus from Grotta all'Onda roamed in search for food within a confined area not far from the cave, where the "Calcare Massiccio" is largely exposed and did not move too far from the area during its whole life.

Resulta llamativo que, tras el Ursus spelaeus, el segundo taxon mas representado sea el gran bovido, lo que puede hacer referencia a esa alternancia entre humanos y carnivoros, como plantea para el nivel VI Martinez Moreno (2005) al hablar del transporte y procesado de carcasas por parte de los grupos humanos a la cueva--se da por supuesto que los ursidos actuales tienen una dieta practicamente vegetariana, y no acarrean, en todo caso, grandes restos oseos a sus cubiles de hibernacion, por lo que tradicionalmente se ha interpretado que el Ursus spelaeus tuviera un comportamiento similar-.
Estas apreciaciones sobre la fauna de las excavaciones antiguas se han visto consolidadas tras el estudio de la fauna correspondiente a los niveles M y N de las nuevas excavaciones--situados por debajo del nivel VI-, en donde se ha observado que los agentes acumuladores en estas unidades fueron basicamente los carnivoros, siendo el taxon mas representado el Ursus spelaeus, que representa el 95% del registro (Arrizabalaga et al., 2010).
