“…For the Mesozoic section we apply the zonation of Roth (1978), because many of the biostratigraphic events used there have since been correlated directly to the magnetochronology in various sections (e.g., Stradner and Steinmetz, 1984;Monechi and Thierstein, 1985). However, due to extreme high latitudes, calcareous nannofossils recovered by ODP Leg 119 are relatively low in diversity.…”

“…Sample preparation of nannofossils was conducted by spreading a fraction of dry sediment on to a cover glass together with a drop of distilled water. This procedure aimed to avoid laboratory contamination and to retain original composition of the sample (see Monechi and Thierstein 1985). The suspension was smeared on the cover glass with the aid of a wooden toothpick and then dried on a hot plate.…”

Animal dung is evaluated here as a tool to reconstruct recent societal and environmental changes. Studies completed on the macro-and micro-contents from dung deposited in a mountain cave in Catalonia during the 1970-1980s, preceding the socio-economic changes in the area, was supplemented by the testimony of the last shepherd alive in the area. This information was also compared with evidence from aerial photographs of the area surrounding the cave taken in 1956 and 2009. Although taphonomic distortion of the dung shape precluded its assignment to its producers based on morphology, information from the organic remains reflects the agro-pastoral activities in the mountainous area of the Catalan coast. A lack of calcium phosphate and abundant phytolith and epidermal remains from wild species indicates that the dung was excreted by ovicaprines, who sheltered in the cave during spells of adverse weather. These indicators also signify that the animals fed only on natural vegetation. Insect remains in the dung include fragments of chafers, dung and ground beetles, bees and ants, and whilst the latter may have foraged in the cave, the others may have been accidentally ingested by herbivores. The nannofossils and diatoms found in the dung derive from tertiary crops 4 km away from the cave but within the range of the ovicaprine herd. The lack of cereal and vegetable remains in the dung is consistent with the ethnographic record that shepherds and farmers could not afford to supplement the herds' diet with fodder crops or grain, a consequence of the low productivity of the local subsistence agriculture. This study further discusses the socio-economic impacts of the introduction of intensive farming, industrialisation and tourism in Catalonia during the latter part of the last century and how they are represented in the dung.

“…Berggren and Miller's (1988), Bolli and Saunders (1985), and Toumarkine and Luterbacher's (1985) zonations were used for the Paleogene. For the Cretaceous the zonations reported by Caron (1985), Kent and Gradstein (1985), and Monechi and Thierstein (1985) were followed. Calibration of planktonic foraminiferal zonation with chronostratigraphy and geochronology followed Berggren et al (1985aBerggren et al ( , 1985b for the Cenozoic and Kent and Gradstein (1985) for the Cretaceous (Fig.…”

Appendix (Shipboard Scientific Party) Following the text of each site chapter are summary downhole logs. Core descriptions ("barrel sheets" and igneous rock visual core descriptions) and photographs of each core appear in Section 3, near the back of this volume. DEFINITIONS Conventional Use of Time and Time-Rock UnitsThe subdivisions of epochs/series into early, middle, late, or lower, middle, upper have no real formal standing in stratigraphy. The subdivision of lithostratigraphic (rock), chronostratigraphic (time-rock), and geochronologic (time) units is defined as follows throughout this volume. Lithostratigraphic UnitsFor rock units, the terms lower, middle, and upper describe sections of rocks subdivided on the basis of superposition, without any implication of time-partitioning.
