Permian conifers were very similar morphologically to their modern counterparts, and were adapted to stressed dry or seasonally dry climatic conditions. [128] The increasing aridity, especially at low latitudes, facilitated the spread of conifers and their increasing prevalence throughout terrestrial ecosystems. [ 134 ]
The range of conifers expanded during the Early Permian to lowlands due to increasing aridity. Walchian conifers were gradually replaced by more advanced voltzialean or "transition" conifers. [11] Conifers were largely unaffected by the Permian–Triassic extinction event, [12] and were dominant land plants of the Mesozoic era.
Walchia is a primitive fossil conifer found in upper Pennsylvanian (Carboniferous) and lower Permian (about 310-290 Mya) rocks of Europe and North America.A forest of in-situ Walchia tree-stumps is located on the Northumberland Strait coast at Brule, Nova Scotia.

The oldest fossils of corystosperms, belonging to Dicroidium, Pteruchus and Umkomasia date to the Late Permian in the low-latitudes of eastern Gondwana, including the Umm Irna Formation of Jordan, as well as the Indian subcontinent, [9] [10] [11] though possible pollen belonging to the group is also known from the Late Permian of South Africa. [12]
Voltziales is an extinct order of conifers.The group contains the ancestral lineages from which modern conifer groups emerged. 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 "voltzian voltziales", also known as "transitional conifers" where the cone is ...
Cordaitales are an extinct order of gymnosperms, known from the early Carboniferous to the late Permian. Many Cordaitales had elongated strap-like leaves, resembling some modern-day conifers of the Araucariaceae and Podocarpaceae. They had cone-like reproductive structures reminiscent of those of modern conifers.
The Port des Canonge Formation is a lower–middle Permian-age geologic formation in the Mediterranean island of Mallorca.It consists of red to brown-colored sedimentary rocks such as sandstone and mudstone, and is located in what back then was the western peri-Tethys Ocean.
