Gymnospermous woods from the Upper Triassic of northern Chile

Abstract

The anatomical study or three gymnosperm fossil woods from the Upper Triassic La Coipa, La Ternera and Las Breas formations is presented. Prototaxoxylon intertappeum is a taxacean wood from India characterized by its tertiary thickenings on their secondary tracheids; Protochamaecyparixylon klitzchii is a cupressaceous wood also present in the Nandanga Formation of South Africa while Protophyllocladoxylon cortaderitaensis is a Protopinaceae member which was already described from the Upper Triassic of Argentina. The present text is the first description of Triassic woods from Chile.
