The Patagonian steppe - a massive rain-shadow on the lee side of the southern Andes - is assumed to have evolved ∼15-12ǎ €‰Myr as a consequence of the southern Andean uplift. However, fossil evidence supporting this assumption is limited. Here we quantitatively estimate climatic conditions and plant...
