cross section / schematic - Surge dynamics of canyon-flushing turbidity currents
Difference maps showing seabed changes (in metres) in the upper Congo Canyon between 2019 and 2020... The grey shaded base map shows seabed gradients in 2020. Shades of red correspond to areas of erosion, and blue to areas of deposition.

[my ‘minor’ in my MSc Geology at the University of Auckland, NZ was in palæontology, and I have had an interest ever since; total aside – <fred.*> is what I call my temp/junk/working files, anyone else?]

maps - Example maps of New Zealand mainland (>73,000 localities), Raukumara Peninsula (>13,000 localities), and detail of Mahia Peninsula (212 localities), to illustrate the density and distribution of fossil localities recorded in the Fossil Record File.
screen shot - Several different query facilities are provided by the FRED interface into the FRF, the most comprehensive of which is the ‘Advanced Query’. The figure depicts a partially populated Advanced Query search screen. Search fields are grouped into various categories (locality, stratigraphy, taxonomic, etc.) and a selection of operators (equals, contains, numeric inequalities, etc.) to allow a series of Boolean statements to be constructed. Full instructions are provided in the on-line user manual.

photos - Left – Two of the most common fossil taxa recorded in the Fossil Record File, a rimu pollen grain, Dacrydium cupressinum (top; scale bar = 20 μm) and the foraminifer Globoquadrina dehiscens (bottom; scale bar = 200 μm). Right (stereo pair) – One of the rarest taxa recorded, the mosasaur Rikisaurus tehoensis (V19/f0068; scale bar = 200 mm). The microfossils have each been recorded more than 5000 times; the mosasaur only once.
