Independent spatial and temporal constraints on paleoelevation and paleoclimate of both the Accepted 20 November 2009 northern and southern plateau are important for understanding the distribution of rapid surface uplift and its Available online 22 December 2009 relation to climate evolution across the plateau. This study focuses on teeth from modern and extinct mammal ∼ Editor: T.M. Harrison taxa (including notoungulates, pyrotheres, and litopterns) spanning 29 Ma to present, collected from the Altiplano and Eastern Cordillera of Bolivia (16.2°S to 21.4°S), and lowland Brazil.
