Based on a comprehensive perusal of experimental results, we construct a microscopic model describing the normal state of layered 4d oxide Sr2 RuO4 incorporating relevant quantum chemical features of the material. The high-T anomalies are explained within a Luttinger liquid (LL) picture. Interlayer one-particle hopping drives a dimensional crossover to a correlated Fermi liquid below a scale E* << tperp. Using recently developed chain-dynamical mean field theory, the low value of E*, as well as various puzzling features of the low-T normal state are explained as manifestations of the crossover from the high-T Luttinger liquid state in a consistent way.
