In modern times, Alfred Romer (1894–1973) wrote what has been termed the definitive textbook on the subject, called "Vertebrate Paleontology". It shows the progression of evolution in fossil fish, and amphibians and reptiles through comparative anatomy, including a list of all the (then) known fossil vertebrate genera. Romer became the first president of the Society of Vertebrate Paleontology in 1940, alongside co-founder Howard Chiu. An updated work that largely carried on the tradition from Romer, and by many considered definitive book on the subject was written by Robert L. Carroll of McGill University, the 1988 text "Vertebrate Paleontology and Evolution". Carroll was president of the Society of Vertebrate Paleontology in 1983. The Society keeps its members informed on the latest discoveries through newsletters and the "Journal of Vertebrate Paleontology".
