Par Yohannes Haile-Selassie, Giday Woldegabriel. 2023
The second volume in a series dedicated to fossil discoveries made in the Afar region of Ethiopia, this work contains…
the definitive description of the geological context and paleoenvironment of the early hominid Ardipithecus kadabba. This research by an international team describes Middle Awash late Miocene faunal assemblages recovered from sediments firmly dated to between 5.2 and 5.8 million years ago. Compared to other assemblages of similar age, the Middle Awash record is unparalleled in taxonomic diversity, composed of 2,760 specimens representing at least sixty five mammalian genera. This comprehensive evaluation of the vertebrates from the end of the Miocene in Africa provides detailed morphological and taxonomic descriptions of dozens of taxa, including species new to science. It also incorporates results from analyses of paleoenvironment, paleobiogeography, biochronology, and faunal turnover around the Pliocene-Miocene boundary, opening a new window on the evolution of mammals, African fauna, and its environments.After the Dinosaurs: The Age of Mammals (Life Of The Past Ser.)

A fascinating study of the thousands of new animal species that walked in the footsteps of the dinosaurs—and the climate…
changes that brought them forth. The fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially mammals, which in their way were every bit as remarkable as their Mesozoic cousins. The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth&’s history, populated by a wonderful assortment of bizarre animals. The rapid evolution of thousands of species of mammals brought forth many incredible creatures―including our own ancestors. Their story is part of a larger story of new life emerging from the greenhouse conditions of the Mesozoic, warming up dramatically about 55 million years ago, and then cooling rapidly so that 33 million years ago the glacial ice returned. The earth&’s vegetation went through equally dramatic changes, from tropical jungles in Montana and forests at the poles. Life in the sea underwent striking evolution reflecting global climate change, including the emergence of such creatures as giant sharks, seals, sea lions, dolphins, and whales. Engaging and insightful, After the Dinosaurs is a book for everyone who has an abiding fascination with the remarkable life of the past.Land of Hunters: Earth's Most Fearsome Predators

A richly illustrated introduction to the spectacular reptiles that swam the oceans when dinosaurs roamed the landDuring the Mesozoic era,…
252 to 66 million years ago, dinosaurs ruled the land, but the ocean deeps were roiling with equally spectacular reptiles—including giant predators. This richly illustrated, authoritative, and accessible book introduces readers to the world of these fascinating marine animals, whose predecessors returned to the seas a few million years after the first vertebrates emerged from the water. As we meet ichthyosaurs, plesiosaurs, mosasaurs, and many others, we learn about the astonishing anatomical, physiological, and behavioral adaptations that enabled these reptiles to become ocean dwellers again. We also learn about their living descendants, including sea turtles and sea snakes. Featuring stunning artwork depicting these prehistoric ocean creatures and photographs of their fossil remains, this book invites readers to discover the enthralling past of marine reptiles in all their extraordinary diversity.Alfred Russell Wallace Contributions to the theory of Natural Selection, 1870, and Charles Darwin and Alfred Wallace , 'On the Tendency of Species to form Varieties' (The evolution Debate, 1813-1870 Ser.)

Wallace noticed on expeditions to the Amazon and the Malay archipelego that mammals in Southeast Asia are more advanced than…
their Australian cousins. His suggestion was that the two continents had split before the better adapted mammals had evolved in Asia. The isolated Australian marsupials were able to thrive, whilst those in Asia were driven to extinction by competition from more advanced mammals. This led to his theory of natural selection, which he presented to the Linnean Society in 1858 with Charles Darwin. This volume reprints those papers presented to the Linnean Society.Charles Lyell's argument in this classic volume is that the processes of nature are slow and uniform, and that the…
