Cambrian Information

The Cambrian Period (541–485 million years ago) was the first period of the Paleozoic Era, marking a dramatic explosion of life known as the Cambrian Explosion. During this time, complex multicellular organisms rapidly diversified, giving rise to the first arthropods, mollusks, echinoderms, and chordates—early ancestors of vertebrates. The climate was generally warm, with high sea levels covering much of the continents, creating vast shallow seas where life thrived. Iconic creatures such as Trilobites, Anomalocaris, and Opabinia dominated the oceans, while the first primitive reefs formed. The Cambrian set the stage for the evolution of modern animal groups and the complexity of marine ecosystems.
