Slopes - Trace Fossils as Indicators of Sedimentary Environments - page 592

Higher diversity slope trace-fossil suites attributable to the Zoophycos Ich-
nofacies commonly comprise grazing structures and deposit-feeding structures
produced by vagile and sessile deposit-feeding organisms. Overall intensities of
bioturbation (as expressed with the Bioturbation Index, BI) are highly variable
(BI

0-5), depending upon the overall sedimentation rate and intercalation of
gravity-flow mudstones. Ambient suites are typically characterized by high
