The Ornithosauria is a book written by Harry Govier Seeley in 1870. The book is an elementary study of the bones of pterodactyls, which are ancient flying reptiles. The study is based on fossil remains found in the Cambridge Upper Greensand, an area in the United Kingdom known for its rich fossil deposits. The book provides a comprehensive overview of the anatomy and structure of the bones of pterodactyls, including their wings, legs, and skulls. It also includes detailed illustrations and diagrams to aid in understanding the complex anatomy of these creatures. The Ornithosauria is an important contribution to the field of paleontology and remains a valuable resource for researchers and enthusiasts interested in the study of pterodactyls and other ancient flying reptiles.And Arranged In The Woodwardian Museum Of The University Of Cambridge.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
