Bouchardia rosea, a vanishing brachiopod species of the Brazilian platform: taphonomy, historical ecology and conservation paleobiology
Dead-live faunal comparisons can offer powerful data to detect natural or human-induced population changes in the late Holocene. Here, we document dead-live comparisons for death assemblages of the brachiopod Bouchardia rosea in nearshore (0-45m) environments along the northern coast of São Paulo St...
