Dinosaurs and Other Life of the Triassic
The second in a series of five books, this book tells the history of life at the start of the Mesozoic Era during the Triassic Period, which was between 252 and 201 million years ago. In this period, the first lepidosaurs (the group containing snakes and lizards) and first archosaurs (the group containing crocodiles and birds) appeared. The first dinosaurs walked the land, the first pterosaurs filled the skies, and the seas were populated by marine reptiles such as ichthyosaurs, plesiosaurs, and others.
