Vertebrate Paleontology is an advanced textbook on vertebrate paleontology by Alfred Sherwood Romer, published by the University of Chicago Press.[1] It went through three editions (1933, 1945, 1966) and for many years constituted a very authoritative work and the definitive coverage of the subject.[2] A condensed version centering on comparative anatomy, coauthored by T.S. Parson came in 1977, remaining in print until 1985.[3] The book provides a very detailed and comprehensive technical account of every main group of living and fossil vertebrates. At the rear of the book is a classification list which includes every genus known at the time of publication, along with locality and stratigraphic range.
