Abstract

The fossil wood studied in this paper was collected in masive gravelly sandstones facies belonging to Paso Flores Formation (Late Upper Triassic). The secondary xylem is of homoxylous structure. Tracheary pitting is protopinoid whilst crossfield pitting is of circoporoid nature. These diagnostic characters allow the recognition of a new species of Protocircoporoxylon Vogellehner.
