Comparisons: This specimen fits the description given by Tanai (1986) for N. magelhaenica, represented by elliptic AP26113 with acute to obtuse base, craspedodromous secondary veins diverging from the pinnate midvein at acute angles and margin serrate with two orders of teeth. This species was originally described by Engelhardt (1891) as Fagus magelhaenica from Southern Chile and later was transferred to Nothofagus by Dusén (1899). This combination was accepted by Tanai (1986) even though she considered that all the specimens illustrated by Dusén (1899) are single-toothed in margin and not belong to magelhaenica. Tosolini et al. (2013) misinterpreted the synonymy proposed by Dutra and Batten (2000) in considering that the all the specimens assigned by Tanai (1986) to N. magelhaenica were reassigned to N. glaucifolia Dutra and Batten.
This species occurs in Eocene–Oligocene deposits from the high latitudes of South America and the Cretaceous of Antarctica (Dusén, 1899 and Tanai, 1986).
