Voltziales

Voltziales is an extinct order of conifers. The group contains the ancestral lineages from which all modern conifer groups emerged. The earliest voltzialean conifers appeared in the Late Carboniferous (Pennsylvanian).[1] Voltzialean conifers are divided into two informal groups, the primitive "walchian conifers" like Walchia, where the ovuliferous cone is composed of radial shoots and the more advanced "volzian voltziales" where the cone is composed of fertile scales with sessile seeds, like those of modern conifers.[2][3] Modern conifer lineages emerged from voltzialean ancestors from the Late Permian to Jurassic.[4] Voltzialean conifers outside modern groups such as Krassilovia/Podozamites survived into the Cretaceous, before becoming extinct.[5] The genus Voltzia was named in honour of the French geologist Philippe Louis Voltz.
