Later Paleozoic seas were dominated by echinoderms (such as sand dollars, star fish, and sea anemones), more advanced kinds of brachiopods, and corals. The principal hallmark of the Ordovician Period was the colonization of the land by arthropods and primitive land plants. By the later part of the Devonian, vertebrates had also colonized the land.A number of lines of seed-bearing gymnospermous plants are discernible among fossil plants of the late Paleozoic Era (541 to 251.9 million years ago) and early to middle Mesozoic Era (251.9 to 66 million years ago). Among them a rather loose assemblage of forms, referred to as seed ferns or as pteridosperms, is well represented.
