The Invasion of Land. Early vascular plants, collectively known as rhyniophytes, first appeared in the late Early Silurian and diversified considerably through the Late Silurian.rthropods are the most diverse group of animals on Earth and include insects, crustaceans, arachnids, myriapods, and onychophorans as well as extinct forms like trilobites. eurypterid. Any member of an extinct order (Eurypterida) of mostly aquatic, scorpion-like arthropods that were common in the early Paleozoic.
Plants divide into two groups: plants lacking lignin-impregnated conducting cells (the nonvascular plants) and those containing lignin-impregnated conducting cells (the vascular plants). Living groups of nonvascular plants include the bryophytes: liverworts, hornworts, and mosses.Vascular plants are the more common plants like pines, ferns, corn, and oaks. The phylogenetic relationships within the plant kingdom are shown in Figure 1.he earliest land plants were most likely bryophytes. Bryophytes lack vascular tissue and have life cycles dominated by the gametophyte phase, as shown in Figure 7. The lack of conducting cells limits the size of the plants, generally keeping them under 5 inches high.
