Echoes of Life is the story of these molecules and how they are illuminating the history of the earth and its life. It is also the...

In this updated and expanded version of his 1982 book Fossils of New Mexico, Kues offers a detailed overview of the fauna and flora of New Mexico through the past 500 million years, from Cambrian through Pleistocene time. An explosion in our knowledge of the state's fossil record has occurred in the past twenty-five years, and in this comprehensive examination Kues thoroughly discusses new discoveries and interpretations as well as the classic New Mexico fossil assemblages that are known worldwide.

After an introductory section covering basic paleontological concepts and a...

The volume contains summaries of facts, theories, and unsolved problems pertaining to the unexplained extinction of dozens of genera of mostly large terrestrial mammals, which occurred ca. 13,000 calendar years ago in North America and about 1,000 years later in South America. Another equally mysterious wave of extinctions affected large Caribbean islands around 5,000 years ago. The coupling of these extinctions with the earliest appearance of human beings has led to the suggestion that foraging humans are to blame, although major climatic shifts were also taking place in the Americas...

The environmental setting within the Central Sahara was subject to considerable changes during Late Quaternary, mainly driven by major global climate variations, although human impact increased constantly since Early Holocene.

Such global events can be reconstructed with the help of reliefs, sediments and palaeosoils and their specific morphological, chemical and mineralogical properties. The project's focus is to ascertain new and established data on climate variations and associated palaeoenvironmental changes within the Central Sahara and to systematically collate and...

Everyone is familiar with the dodo and the wooly mammoth, but how many people have heard of the scimitar cat and the Falkland Island fox? Extinct Animals portrays over 60 remarkable animals that have been lost forever during the relatively recent geological past. Each entry provides a concise discussion of the history of the animal--how and where it lived, and how it became extinct--as well as the scientific discovery and analysis of the creature. In addition, this work examines what led to extinction--from the role of cyclical swings in the Earth's climate to the spread of humans...
