This talk will review several frontier issues in primordial and early galactic nucleosynthesis. The possible confrontation between primordial nucleosynthesis constraints on the present baryon-to-photon ratio and that implied by recent measurements of the cosmic microwave background will be discussed. We will highlight various means to resolve this possible disagreement by the introduction of neutrino degeneracy or other modifications to the standard big bang. In the second part of this talk we will explore new paradigms for the nucleosynthesis of heavy elements by neutron capture in the early Galaxy. Most metal-poor early stars exhibit enhanced abundances of elements formed by rapid neutron capture (the r-process). We will review the difficulties which current r-process models have for explaining the observed abundances and explore new mechanisms which may be required to account for the observations. We will also review evidence for a new mechanism for slow neutron-capture (the s-process) nucleosynthesis based upon recent observations of an s-process enhanced metal-poor star in the galactic halo.
