Evolution of Gymnosperms. Figure 26.1 B. 1: Seed ferns: This fossilized leaf is from Glossopteris, a seed fern that thrived during the Permian age (290–240 million years ago). The fossil plant Elkinsia polymorpha, a “seed fern” from the Devonian period (about 400 million years ago) is considered the earliest seed plant known to date. Leaves are only one of the structures preserved in the fossil record. We have also found fossilized stems, cones, and seeds, all of which help us to reconstruct the appearance and biology of these ancient plants. In addition to the eleven living genera, many of which are known as fossils, there are 19 extinct cycad genera known only as fossils.

There is increasing evidence that many fossil seed plants had developed more than chance associations with insects, which may have served as secondary pollinators as early as the Pennsylvanian. For example, Harris (1969) noted that the resin-containing “synangia” on the bracts of the pollen cone Weltrichia may represent some form of attractant.
