After summarizing the evidence for dark baryonic matter in various environments, I review theoretical considerations relevant to the nature of such a component of the universe in regions where it is the dominant mass fraction. Phenomenological constraints are given on the primordial stellar initial mass function. The primordial rate of star formation is evaluated during the early stages of galaxy formation, utilizing simple theoretical considerations motivated by present day star formation rates. Applications are given to predominantly dark objects whose existence is inferred from galaxy formation theory, including low surface brightness giant and dwarf galaxies. Prospects for detection of dark populations that dominate our own galactic halo are described.
