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 Podozamites, survived into the Cretaceous.[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:

• Utrechtiaceae
• Thucydiaceae
• Emporiaceae
• Majonicaceae
• Ullmanniaceae
• Bartheliaceae
• Ferugliocladaceae
• Buriadiaceae
• Krassiloviaceae
