May 1, 2020 · We evaluate the paleoecological boundary conditions controlling the distribution of Terebratula by estimating its environmental tolerances using benthic and planktic foraminiferal and nannoplanktic assemblages and oxygen isotopes of the secondary layer brachiopod calcite. Lingula is a well known inarticulate brachiopod. , 2002: Victims of the Early Toarcian anoxic event, the radiation and extinction of Jurassic Koninckinidae (Brachiopoda).
