When Bugs Were Big, Plants Were Strange, and Tetrapods Stalked the Earth PDF ePub eBook

Books Info:

When Bugs Were Big, Plants Were Strange, and Tetrapods Stalked the Earth free pdf "When Bugs Were Big" takes the reader back to the coal swamps of 320 million years ago when the continents were all grouped together, and there was only one giant ocean. Over the next 100 million years, amphibians and insects grew huge and reptiles made their first appearance. This prehistoric prequel is a portrait of a world that came to a crashing halt 250 million years ago in one of the greatest extinctions of all time, paving the way for the rise of the dinosaurs. Age-appropriate appendixes, including a time line of life on Earth and a chart to help keep vertebrates straight, make this an excellent educational resource.
