Stratigraphy
Lithology and environment
Primary lithology:lag calcareous tuff
Lithology description: a calcareous palagonite tuff of basaltic composition with beds of lapillistone and tuff-breccia soft, poorly bedded, bryozoan grainstone and minor echinoid-spine packstone
Environment:transition zone/lower shoreface
Geology comments: bedding and textural features indicative of a mid-shelf to upper-bathyal life setting
Taphonomy
Modes of preservation:body
Size of fossils:mesofossils,microfossils
Collection methods and comments
Collection excludes:some macrofossils
Reason for describing collection:taxonomic analysis
Collection method comments: PREPARATION: Individual bryozoans could be picked out of the limestone whereas bulk collections were collected for later washing, sieving and sorting. Specimens were studied by scanning electron microscopy using a LEO 1455VP SEM at the Natural History Museum, London, UK and a Hitachi TM3000 Tabletop Microscope at the National Institute of Water and Atmospheric Research, Wellington, New Zealand.
