We investigate cosmological behavior in the quasidilaton nonlinear massive gravity. We perform a detailed dynamical analysis and examine the stable late-time solutions relevant to late-time cosmic acceleration. We demonstrate that a dark-energy-dominated, cosmological-constant-like solution is a late attractor of the dynamics. We also analyze the evolution of the universe at intermediate times, showing that the observed epoch sequence can be easily obtained in the model under consideration. Furthermore, we study the nonsingular bounce and the cosmological turnaround which can be realized for a region of the parameter space. Last but not least, we use observational data from type Ia supernovae, baryon acoustic oscillations and the cosmic microwave background in order to constrain the parameters of the theory.
