Late Miocene freshwater mussels from the intermontane Chota Basin, northern Ecuadorean Andes

Prior to the development of the modern Amazonian drainage network during the Late Miocene-Early Pliocene, large areas of western Amazonia may have been occupied by an extensive lacustrine and wetland environment known as the Pebas and Acre systems. These depositional systems are thought to have form...
