“…While shallow biogenic structures are common in Proterozoic and early Palaeozoic shallow marine clastic successions, they became increasingly rare in younger strata (Thayer 1983;Droser and Bottjer 1993). Savrda and Ozalas (1993) noted that the potential for preservation of shallow traces is enhanced when environmental conditions deviate from the steady state. Preservation of decapod trackways in Cretaceous open marine deposits may be explained by invoking stress factors that may have isolated the mixed layer from subsequent bioturbation.…”

ABSTRACT. A new trace fossil, Foersterichnus rossensis igen. nov. and isp. nov., is described from the Coniacian Hidden Lake Formation, James Ross Island, Antarctica. The trace fossil is a trackway comprising straight, or slightly curving, paired rows of elongate to tear-shaped impressions, parallel or slightly inclined to the long axis of the trackway. Foersterichnus is interpreted to be the trackway of a brachyuran decapod crustacean. It occurs in transgressive shallow marine deposits formed above the storm wave base in a shelf setting. Preservation of the trackway may have been linked to a rapid deoxygenation event during drowning that led to cessation of bioturbation allowing preservation of mixed layer trackways.

This study tested the potential for highresolution quantitative biostratigraphic methods to distinguish tectonic from supposedly eustatic sequences. The study employed automated multidimensional graphic correlation using constrained optimization (program CONOP). Our analysis was based on 15 onshore sections in eastern New Zealand spanning the Coniacian to Maastrichtian stages (Upper Cretaceous), and 398 wellconstrained lowest-or highest-occurrence records derived from 245 dinofl agellate species. The age of the resulting composite section was calibrated using six dated bioevents; two of these events were tied to geochemical or paleomagnetic datums. Following calibration, the composite section had an average relative temporal resolution of less than 130 k.y. through the study interval, although the succession of events was not dated to this level of precision in an absolute sense. Although the CONOP composite will not resolve unconformities or condensed intervals that occur across all studied sections, such "global" unconformities can be identifi ed using clusters of events that are placed at a single composite level. Fifteen major event clusters were identifi ed, 10 of which coincided closely with sequence boundaries identifi ed in the Northern Hemisphere; the probability of this coincidence arising by chance alone is ~8%. Although these results must be regarded as provisional, they suggest that high-resolution quantitative stratigraphy can provide a potent tool for the identifi cation and correlation of stratigraphic sequences. Furthermore, our fi ndings add signifi cant support for recent studies that have argued for the presence of Late Cretaceous eustasy.

“…A Late Maastrichtian age for the Sandwich Bluff Member is based on an array of biostratigraphic evidence. Abundant marine reptiles, a hadrosaurian dinosaur tooth, macro-invertebrates, and micro-invertebrates have been sampled from deposits directly overlying the concretionary layer that produced the Vegavis holotype (Pirrie et al, 1991;Case et al, 2000;Riding et al, 1992;Martin, 2006;reviewed in Clarke et al, 2005).…”
