-VOLTZIALES AND PINALES (= CONIFERALES) FROM CORTADERITA FORMATION (MIDDLE TRIASSIC), ARGENTINA, AND THEIR IMPLICATION IN THE RECONSTRUCTION OF TRIASSIC CONIFERS.In this work, fossil wood, leaves, and branches designated to the subclass Pinidae (Voltziales and Pinales) are described from Cortaderita Formation (Middle Triassic). Fossil materials were collected at Cortaderita and La Tinta creeks, at Barreal area from Barreal-Calingasta basin, Pre-Andean region of San Juan, Argentina. Leaves corresponding to three species of Heidiphyllum (order Voltziales), leafy twigs assigned to Elatocladus planus (Pinales) and permineralized trunks and branches ascribed to Cupressinoxylon zamunerae sp. nov. (Pinales), were recognized. The last two species exhibit characters that allow designating them to family Cupressaceae sensu lato. At the same time, it is demonstrated that they belong to the same plant, which is named as the new species of Cupressinoxylon here described. This reconstruction is based on kindred reinforcement and mutual occurrence criteria, besides morphological and anatomical characters. Thus, Cupressinoxylon zamunerae sp. nov. is interpreted as a tree 13 m tall, highly branched, with penultimate order shoots with scale-like leaves and last order shoots with alternate, sessile, single-veined, linear to acicular leaves distributed helically. These records confi rm the presence of Cupressaceae sensu lato since the Triassic in Gondwana.Key words: Barreal-Calingasta, Sorocayense Group, Voltziaceae, Cupressaceae sensu lato.RESUMO -Neste trabalho são descritos lenhos, folhas e ramos para a subclasse Pinidae (Voltziales e Pinales) da Formação Cortaderita (Triássico Médio). Os materiais foram encontrados nas quebradas La Cortaderita e La Tinta, na área de Barreal, bacia de Barreal-Calingasta, precordillera de San Juan, Argentina. Foram reconhecidas folhas correspondentes a três espécies do gênero Heidiphyllum (Voltziales), ramos folhosos atribuídos a Elatocladus planus (Pinales) e lenhos permineralizados designados como Cupressinoxylon zamunerae sp. nov. (Pinales). As duas últimas espécies têm características que permitem atribuí-los para a família Cupressaceae sensu lato. Por isso, neste estudo mostra-se que correspondem a mesma entidade biológica. Assim é descrito com o nome da nova espécie de Cupressinoxylon. Esta reconstrução é baseada em critérios de reforço mútuo e de ocorrência afi ns, além de características morfológicas e anatômicas. Desta forma, Cupressinoxylon zamunerae sp. nov. é interpretada como uma árvore de aproximadamente 13 m de altura, muito ramifi cada, com ramos da penúltima ordem com folhas escamiformes, e ramos de última ordem alternados, com folhas sésseis, uninerveadas, lineares a aciculares distribuídas helicoidalmente. Esses registros confi rmam a presença de Cupressaceae sensu lato, desde o Triássico no Gondwana desde o Triássico. Palavras-chave:Barreal-Calingasta, Grupo Sorocayense, Voltziaceae, Cupressaceae sensu lato.

In the North of Mendoza Province, at Paramillos de Uspallata locality, Triassic sedimentary rocks outcrop. These Triassic beds are grouped in four formations: Paramillos, Agua de la Zorra, Portezuelo Bayo and Los Colorados. The Agua de la Zorra Formation is characterized by deposition in a deltaic and lacustrine system. The aims of this contribution are: (1) to realize a systematic study of new plant remains found in the Agua de la Zorra Formation and (2) to analize the influence of the potential of preservation and the volcanism in the Agua de la Zorra taphoflora in contrast with other Triassic units. Plant remains were systematically collected and compared with taphofloras from other Triassic formations of the Cuyana Basin. The systematic study from the Agua de la Zorra Formation allowed the determination of 21 taxa, nine of which have been cited in a previous contribution and 12 were described for the first time for the Agua de la Zorra Formation. There are differences in the taxonomic diversity between the taphofloras recovered from Potrerillos and Paramillos formations and these differences are linking with differences in biostratinomic process in each fluvial system and linked with the evidence of volcanic processes in these areas. The differences in diversity in the taphofloras of the Cacheuta and Agua de la Zorra formations can be more associated to ecological differences than variations in the taphonomic processes in each of the lake systems.
