Resumen:
Abstract. Planoxylon Stopes, Protelicoxylon Phillipe and Herbstiloxylon nov. gen. (Coniferales) from the Middle Jurassic La Matilde Formation, Santa Cruz province, Argentina. The following petrified wood taxa are described as a new record for the Middle Jurassic La Matilde Formation, Gran Bajo de San Julián, Santa Cruz province, Argentina: Planoxylon australe (Salard) Vozenin- Serra and Salard-Cheboldaeff and Protelicoxylon feriziense (Fahkr and Marguerier) Philippe. A new genus and species of Herbstiloxylon patagonicum is also described. Planoxylon is a member of the Protopinaceae which is characterized for including wood specimens with transitional characters between araucarioid and abietinoid types. The affinities of Planoxylon and Protelicoxylon are analized and related them to the Cupressaceae (Coniferales), due to the presence of callithroid thickenings.
