Podozamites

Podozamites is an extinct genus of Mesozoic conifer leaves. In its broader sense, it has been used as a form taxon to refer to any broad leaved multi-veined conifer leaves, some of which probably belong to extant conifer groups including Araucariaceae. In a more narrow sense, it has been used to refer to a probably monophyletic group of broad leafed conifers that existed in the Northern Hemisphere, particularly East Asia and Siberia during the Late Triassic to early Late Cretaceous, where it formed part of wet coal swamp communities. Over the course of the Jurassic, the distribution shifted northwards in response to the drying of the lower latitudes, becoming restricted to between 60 and 30 degrees North by the Early Cretaceous. Podozamites would become extinct during the early Late Cretaceous, coincident with the arrival of flowering plants into the region.^[1] Podozamites leaves are thought to have been regularly shed. Podozamites leaves sensu stricto are associated with conifer cones of the genera Swedenborgia, Cycadocarpidium, and Krassilovia, and were suggested in 2020 to constitute the distinct family Krassiloviaceae within the Voltziales.^[2]
