Hexaplexhertweckorum

 

The muricid snails have highly spinose shells.  Shown below is a spectacular, complete fossil muricid snail shell with unbroken spines.  The only significant alteration thatís taken place is natural bleaching of the original coloration (cf. with 2nd picture below of a living species).
