La paleoflora triásica del cerro Cacheuta, provincia de Mendoza, Argentina. Bryopsida, Lycopsida, Sphenopsida, Filicopsida y Gymnospermopsida (Corystospermales y Peltaspermales)

First record of Ginkgo-related fertile organs (Hamshawvia, Stachyopitys) and leaves (Baiera, Sphenobaiera) in the Triassic of Brazil, Santa Maria formation

“…10,13) in the synonym of S. sectina. The bigger and coriaceous leaves, with numerous, bifurcate and thick veins of S. argentinae (Frenguelli, 1946;Artabe, 1985;Anderson and Anderson, 1989;Morel et al, 2011) are also very distinct from the herein (Table 2).…”

Evolution and Relationships of the Conifer Seed Cone Telemachus: Evidence from the Triassic of Antarctica

“…The co-occurrence of more than one species of Telemachus was also reported from the Triassic Cacheuta Formation in Mendoza Province, Argentina (Morel 1994), where T. elongatus and Telemachus lignosus occur at the same locality. As in Antarctica, these two Telemachus species are found in association with the single leaf type, H. elongatum (Morel 1994).…”

“…As in Antarctica, these two Telemachus species are found in association with the single leaf type, H. elongatum (Morel 1994).…”

“…The genus was subsequently discovered in a number of localities throughout Gondwana, including the Middle Triassic of New Zealand (Retallack 1981), Antarctica (Yao et al 1993;Axsmith et al 1995Axsmith et al , 1998, Argentina (Morel 1994;Lutz 2006), and Chile (Nielsen 2005). As a result of these reports, Telemachus represents the most widely distributed conifer seed cone from the Triassic of Gondwana.…”

“…However, the cone from which the ovules were obtained was mature and the ovules disassociated, suggesting that the ovules described by Yao et al (1993) could represent contaminants. Morel (1994) and Lutz (2006) briefly mentioned the presence of ovules in Telemachus cones from two different Triassic basins in Argentina and indicated that there were from two to four ovules per cone scale.…”
