No, "Spinosaurus B" is regarded as material belonging to
_Carcharodontosaurus_ by Sereno et al. (in the Sereno et al. 1996 paper on
_Carcharodontosaurus_ and _Deltadromeus_), but is considered as belonging to
its own taxon (_Sigilmassaurus_) by Russell.
Neither group seems to consider the material as being spinosaurid.
