Within turbidites of the upper part of this sequence are numerous olistoliths, up to 250 m long. These are not parts of olistostromes, or other mass movement deposits, but appear to have travelled into the basin independently; hence the term 'isolated olistolith' seems appropriate for them. Soft-sediment deformation structures around the margins of one well-exposed olistolith suggest an analogy with'outrunner-blocks' recently described from a modern submarine slope-failure complex by . In both cases the blocks appear to have travelled considerable distances across very low slopes without disturbing the underlying sediments to any great extent. Transport probably occurred relatively rapidly with the aid of overpressuring of the underlying sediments.

The biological information available from this record is outlined here. In particular palaeontological perspectives on coccolith based taxonomy and phylogenetic inferences are described. It is shown that the geological record of coccoliths is selective, but very complete for the selected species. Research on exceptionally preserved fossil coccoliths, the Cretaceous/ Tertiary boundary, palaeoceanography, and Milankovitch cyclicity is outlined.

These include taxon occurrence data for ecological modeling, as well as information that can be used to reconstruct mechanisms through which biota respond to changing climates. The full potential of NHCs for climate change research cannot be fully realized until high-quality data sets are conveniently accessible for research, but this requires that higher priority be placed on digitizing the holdings most useful for climate change research (e.g., whole-biota studies, time series, records of intensively sampled common taxa). Natural history collections must not neglect the proliferation of new information from efforts to understand how present-day ecosystems are responding to environmental change. These new directions require a strategic realignment for many NHC holders to complement their existing focus on taxonomy and systematics. To set these new priorities, we need strong partnerships between NHC holders and global change biologists.

Whereas very few field surveys have operated for more than a few decades, NHCs, conserved in museums and other institutions, comprise samples of the Earth's biota typically extending back well into the nineteenth century and, in some cases, before this time. They therefore span the period of accelerated anthropogenic habitat destruction, climate warming and ocean acidification, in many cases reflecting baseline conditions before the major impact of these factors.
