A lower triassic miospore assemblage from the Puesto Viejo formation, Argentina

Twenty-three species of miospores, distributed among 16 genera have been recovered from the basal section of the Puesto Viejo Formation, near San Rafael City, Mendoza Province, Argentina. The sequence is dated as Early Triassic on the evidence of fossil vertebrates. One new species, Aratrisporites s...
