The Cambrian Period was a critical time in Earth's history. During this immense span of time nearly every modern group of animals appeared. Cambrian rocks preserve the record of the first appearance of complex animals with eyes, protective skeletons, antennae, and complex ecologies. Grazing, predation, and multi-tiered ecosystems with animals living in, on, or above the sea floor became common. The cascade of interaction led to an ever-increasing diversification of animal body types. By the end of the period, the ancestors of sponges, corals, jellyfish, worms, mollusks, brachiopods, arthropods, echinoderms, and vertebrates were all in place. Cambrian Ocean World: Ancient Sea Life of North America presents life and times of the animals that inhabited Earth more than 500 million years ago. 457 p.
