This volume, aimed at the general reader, presents life and times of the amazing animals that inhabited Earth more than 500 million years ago. The Cambrian Period was a critical time in Earth's history. During this immense span of time nearly every modern group of animals appeared. Although life had been around for more than 2 million millennia, 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. The evidence of this Cambrian "explosion" is preserved in rocks all over the world, including North America, where the seemingly strange animals of the period are preserved in exquisite detail in deposits such as the Burgess Shale in British Columbia. Cambrian Ocean World tells the story of what is, for us, the most important period in our planet's long history.

The Cambrian radiation was the explosive evolution of marine life that started 550,000,000 years ago. It ranks as one of the most important episodes in Earth history. This key event in the history of life on our planet changed the marine biosphere and its sedimentary environment forever, requiring a complex interplay of wide-ranging biologic and nonbiologic processes. The Ecology of the Cambrian Radiation offers a comprehensive and surprising picture of the Earth at that ancient time. The book contains contributions from thirty-three authors hailing from ten countries and will be of interest to paleontologists, geologists, biologists, and other researchers interested in the global Earth-life system.

This book was released on 2022-03-17. The Cambrian Way available in PDF, EPUB and Kindle. Dubbed 'the mountain connoisseurs' walk', the Cambrian Way stretches 479km between the mighty castles of Cardiff in the south and Conwy on the north coast. Traversing the heartland of Wales, the challenging route crosses the Brecon Beacons, the Cambrian Mountains and Snowdonia, passing through two national parks and visiting many of the country's iconic summits, including Pen y Fan, Pumlumon, Cadair Idris and Snowdon itself. It can be walked in three weeks (or in shorter sections) and is suitable for experienced hillwalkers with sound navigational skills. The guide presents the route in 21 stages, offering comprehensive route description illustrated with OS 1:50,000 mapping and elevation profiles. Details of accommodation and facilities are provided, along with a helpful trek planner showing their distribution along the route: although the trail passes through remote areas, it is possible to stay under a roof every night - though camping is also a possibility, should you prefer. There are background notes on Wales's history and geology and local points of interest, and a glossary of Welsh place-names, useful contacts and accommodation listings can be found in the appendices. From the Black Mountains to the Rhinogau, Glyderau and Carneddau, the route takes in lofty ridges, striking peaks and picturesque lakes. There are also fascinating glimpses into the country's ancient and more recent past: Iron Age hillforts, Norman castles, a Cistercian abbey, the Chartist Cave and relics from the mining industry. Offering superlative scenery, the Cambrian Way is a celebration of some of the best mountain walking Wales has to offer and promises a unique opportunity to immerse yourself in these celebrated landscapes.
