Geinitzia is an extinct genus of conifers, with an uncertain position within the group, yet has been considered to be part of it´s own family, Geinitziaceae.[1] The definition of the taxon is complex, a two options are managed:
- Accepted in the interpretation of the form-genus/morphogenus, and so with specimens tougth the Late Paleozoic–Mesozoic of Europe.[2]
- Accepted as a natural genus of Cretaceous-Tertiary conifers.[2][3]
Species belonging to the genus mostly lived in the late Cretaceous and have been found in Argentina and Europe.[4][5][6]
Species
A number of species have been described in Geinitzia.
