Voltziales is an extinct order of conifers. The group contains the ancestral lineages from which all modern conifer groups emerged. The earliest Voltzialean conifers appear in the Late Carboniferous (Pennsylvanian).[1] Modern conifer lineages emerged from voltzialean ancestors from the Late Permian to Jurassic.[2] Voltzialean conifers outside modern groups such as Krassilovia/Podozamites survived into the Cretaceous, before becoming extinct.[3] One of the earliest and most primitive genera is Walchia, known originally for its leaf form genus, and primitive members of the order are commonly called "Walchian conifers".[4] The order consists of these families:[citation needed]
- Utrechtiaceae
- Thucydiaceae
- Voltziaceae
- Emporiaceae
- Majonicaceae
- Ullmanniaceae
- Bartheliaceae
- Ferugliocladaceae
- Buriadiaceae
