Summary: We establish that the effective model of a layered solid-fluid medium is a special case of the Biot model. By proving this statement, several intermediate media are considered, and for each medium the fronts from a point source are determined. These fronts can have double loops while the loops on corresponding fronts in elastic anisotropic media can be only single.
