Fossilized frond of the seed fern Mariopteris sp.. The seed ferns differed from the more primitive true ferns by possessing seeds and not spores. Although their foliage resembles that of the true ferns, seed ferns rank among the simplest of the spermatophyta - the group containing the conifers and flowering plants. Such plant remains contributed greatly to the formation of coal.
