Coniferopsida In some classifications, a subdivision of the gymnosperms, comprising 4 orders, the oldest of which, the Cordaitales, appeared in the Carboniferous. They became extinct at the end of the Permian, but their place was taken by 2 other coniferopsid orders: the Ginkgoales (ginkgos) and Coniferales (conifers). These are now usually ranked as divisions, the Ginkgophyta and Coniferophyta.
