Abstract

AGUIRRE-URRETA, Beatriz  and  VENNARI, Verónica. On Darwin's footsteps across the Andes: Tithonian-Neocomian fossil invertebrates from the Piuquenes pass. Rev. Asoc. Geol. Argent. [online]. 2009, vol.64, n.1, pp.32-42. ISSN 0004-4822.

The aim of this work is to summarize the modern knowledge of the geology of the Piuquenes Pass, in the Main Andes of Argentina and Chile, and to describe a small fauna of Tithonian-Neocomian invertebrates mostly represented by ammonites. The present knowledge of the region is compared with Darwin's, as expressed in his famous book on the Geology of South America.

Keywords : Main Andes; Mesozoic; Ammonites; Piuquenes Pass; Darwin.
