  We consider a superextension of the extended Jordanian twist, describing
nonstandard quantization of anti-de-Sitter ($AdS$) superalgebra $osp(1|4)$ in
the form of Hopf superalgebra. The super-Jordanian twisting function and
corresponding basic coproduct formulae for the generators of $osp(1|4)$ are
given in explicit form. The nonlinear transformation of the classical
superalgebra basis not modifying the defining algebraic relations but
simplifying coproducts and antipodes is proposed. Our physical application is
to interpret the new super-Jordanian deformation of $osp(1|4)$ superalgebra as
deformed D=4 $AdS$ supersymmetries. Subsequently we perform suitable
contraction of quantum Jordanian $AdS$ superalgebra and obtain new
$\kappa$-deformation of D=4 Poincare superalgebra, with the bosonic sector
describing the light cone $\kappa$-deformation of Poincare symmetries.
