Life in the Cambrian and Ordovician - GEO GIRL

Explore the fascinating world of Early Paleozoic life in this comprehensive 27-minute video covering major life events and organisms from the Cambrian and Ordovician periods. Delve into the evolution of early burrowers, skeletonized fauna, and soft-bodied organisms. Discover the emergence of huge Cambrian predators, diverse modes of life, and the development of early reefs. Learn about evolutionary experimentation, the appearance of the first vertebrates, and the significance of the Burgess Shale. Examine Ordovician life, including convergent evolution of shells, the Great Ordovician Biodiversification, and the rise of new predators. Conclude with an overview of the Ordovician Mass Extinction and its impact on Earth's biodiversity.
