Plants from the paleozoic era
During the Paleozoic Era, evolutionary innovation moved onto land, as plants and, subsequently, at least nine clades of animals established what would become Earth’s most diverse, productive, and biomass-rich ecosystems. ... Plants began the period as centimeter-scale, naked photosynthetic axes and exited it with leaves, roots, wood, …What plants were on Earth during the Cambrian Period? Many types of algae lived in the ocean. Land plants had not yet evolved. What was Virginia like during the Cambrian Period? All of Virginia was under water during the Cambrian! The sediments from that sea are limestones, shales, and sandstones today.
