This may have begun to change later, as land plants became more common. As the roots of land plants began to infiltrate rock and soil began to form, carbon dioxide was drawn out of the atmosphere and became trapped in the rock.During the Paleozoic Era, there were multi-cellular organisms like trilobites, mollusks, jawless fish, seaweeds and finally, jawed fish, sharks, plants and early amphibians and reptiles.The Mesozoic Era is divided up into the Triassic, Jurassic, and Cretaceous periods.
