Throughout the Dinosaur Age, enormous reptiles called ichthyosaurs, plesiosaurs, and mosasaurs swam the seas. Some of these massive creatures weighed more than 20 tons. Others had snake-like necks as long as 23 feet. From Kansas and Canada to Antarctica and New Zealand, fossil bones of these real-life sea monsters have been found.

Acclaimed science author Caroline Arnold and noted natural-history artist Laurie Caple pair up once again to show how fossil evidence worldwide is helping us learn about these amazing reptiles. Featuring eerily beautiful illustrations that bring “fossil creatures” to life, this thoroughly researched book gives insight into what Earth was like when prehistoric predators roamed the seas. Author’s note, index.

When the weather becomes extreme or even unseasonal, "El Nino" is usually the phrase we hear. Every three to seven years, El Nino disrupts weather all over the globe, second only to the change of seasons in its influence on the climate. But what is El Nino? El Nino is the name given to the unusual increase in ocean temperatures along the Peruvian and the Ecuadorian coasts that is part of a larger pattern of changes in wind and weather throughout the world. With El Nino come violent storms and upsets in global food chain that dramatically affect both humans and wildlife. Effects can be as gentle as a mild winter in northeastern United States or as violent as drought in Southeast Asia, brutal storms in South America, and wildfires in Australia. With the help of carefully selected photographs and clarifying charts and maps, Caroline Arnold makes clear how this remarkable weather pattern forms, how scientists track it, what its effects are, and why following its path is of such importance.

Dinosaurs are usually pictured in warm, tropical environments, but fossils found at the poles are filling in the gap of knowledge about how and where these creatures lived. Evidence from bones and teeth to trackways and skin impressions raises important questions: How did dinosaurs cope with three months of total darkness in winter? What plants grew in the polar regions? How cold was it? What are the implications for today, as glaciers retreat, ice shelves melt, and permafrost thaws? The polar regions are a unique "library" of the past, and Caroline Arnold introduces readers to the gigantic prehistoric creatures that inhabited them.
