Abstract—We provide a bibliography of Arizona vertebrate paleontology that consits of approximately 625 references covering vertebrate occurrences ranging in age from to Holocene. Not surpris- ingly, references to and Neogene vertebrates are the most numerous, reflecting the particular strengths of the Arizona record. We break the bibliography down into various taxic groups and provide a complete, unified bibliography at the end of the paper. Keyworks: Arizona, bibliography, , vertebrate, paleontology
