Entitled: Fossil record of early Cambrian times. Some are drawn nearly life-size. Among them are arthropods (D and K - O), mollusks (B, E and perhaps, F and G), brachiopods (I, J), echinoderms (H), sponges (A), and other organisms such as (C) that probably belong to phyla, or animal groups, that became extinct long ago. The Cambrian is the first geological period of the Paleozoic Era ( million years ago) and is succeeded by the Ordovician. The rapid diversification of lifeforms in the Cambrian, known as the Cambrian explosion, produced the first representatives of many modern phyla, representing the evolutionary stems of modern groups of species, such as the arthropods.
