Zapata Formation (Argentina)

Zapata Formation ( Spanish: Formación Zapata) is a sedimentary formation of Lower Cretaceous age in the Magallanes or Austral Basin of Argentina and Chile. Much of the formation is folded and faulted as consequence of the Andean orogeny. ^[1] In outcrops of the Zapata Formation near Torres del Paine, the ichthyosaur genus Myobradypterygius has been found. ^{[2] [3]}
