  We discuss several highly accurate theoretical predictions for masses of
baryons containing the b quark which have been recently confirmed by
experimental data. Several predictions are given for additional properties of
heavy baryons. We also discuss the two charged exotic resonances Z_b with
quantum numbers of a (b bbar u ddbar) tetraquark, very recently reported by
Belle in the channel [Upsilon(nS) \pi^+, n=1,2,3]. Among possible implications
are deeply bound I=0 counterparts of the Z_b-s and existence of a Sigma_b^+
Sigma_b^- dibaryon, a "beauteron".
