Water Reptiles of the Past and Present

"Water Reptiles of the Past and Present" by Samuel Wendell Williston is a scientific publication written in the early 20th century. The work provides an authoritative account of various water reptiles, both extinct and extant, drawing on the author's extensive research and discoveries from his early career in paleontology. The text endeavors to be accessible to a non-specialist audience while retaining scientific accuracy and detail. The opening of the book begins with Williston's preface, which reflects on his early experiences collecting fossil water reptiles, such as mosasaurs and plesiosaurs, and outlines the book's purpose to document these creatures for a wider audience. He expresses gratitude to contemporaries and contributors in the field for their assistance and resources. Following the preface, the introduction discusses the common misconceptions surrounding reptiles, highlighting their diversity and the evolutionary connections among reptiles, amphibians, and mammals. It lays the groundwork for understanding reptilian classification and anatomy, leading into the subsequent chapters that delve into more specific aspects of reptilian biology and fossil records.
