We combined available molecular sequences and a new morphological data set in order to investigate basal relationships and to place a number of fossil taxa within the caprimulgiform tree, a goal being to estimate the temporal history of the group. Our results support the monophyly of Caprimulgiformes with an included “apodiform” clade, with some reservations regarding the inclusion of Steatornis. The relationships among the families outside the “apodiform” clade are not congruent across the different analyzes due to a fundamental difference in the molecular and morphological results regarding the relationship of the Caprimulgidae with Nyctibiidae and Podargidae. The inclusion of numerous fossil taxa in the morphological data set, and as constraints for molecular dating analyses adds important information regarding the temporal history, suggesting a Cretaceous origin of the Caprimulgiformes with the “apodiform” clade evolving in the early Palaeogene and the modern hummingbirds (Trochilidae) in the Eocene.AOU meeting 12-15 august 2009 PhiladelphiaAbstract (5552)</blockquote>
