A nonstandard super extensions of the Poincaré algebra (S-algebra1,2), which seems to be relevant for construction of various D = 11 models, are studied. We present two examples of actions for point-like dynamical systems, which are invariant under off-shell closed realization of the S-algebra as well as under local fermionic κ-symmetry. On this ground, an explicit form of the S-algebra is advocated.
