The partial differential equation describing the shape of the wave front caused by a two-dimensional point impulsive source in transversely isotropic elastic media is formulated and solved. The important role played by the slowness curve in establishing key features of the wave front is discussed. Recent research on the existence of slowness curve inflection points, experimental verification of anisotropic elastic wave front shapes in crystals, and the wave front from a circular distributed source are briefly discussed.
