In this paper we give geometric definitions of the Lorentzian ellipse, Lorentzian hyperbola, and Lorentzianparabola as plane curves in Lorentzian plane. Moreover we obtain the equations of Lorentzian revolutionellipsoid, Lorentzian revolution hyperboloid and Lorentzian revolution paraboloid respectively
