Abstract
⺠The Newport Member provides a test for shallow-water dysoxia during global warming. ⺠Abundances of Buliminacea, Fursenkoina, and Nonionella increase after warming. ⺠The δ13C offset between semi-infaunal and infaunal species suggests high organic flux. ⺠Laminated sediments increase and bioturbation decreases suggesting low oxygen. ⺠Organic-rich, low-oxygen conditions may be analogous to hypoxia in modern Oregon.
