  It is argued that in heavy ion collisions at LHC there could be a sizeable
production of baryons containing two or three heavy quarks from statistical
coalescence. This production mechanism is peculiar of Quark Gluon Plasma and
the predicted rates, in heavy ion collisions at LHC energy, exceed those from a
purely hadronic scenario, particularly for Xi_bc and Omega_ccc. Thus, besides
the interest in the discovery of these new states, enhanced ratios of these
baryons over singly heavy flavoured hadrons, like B or D, in heavy ion
collisions with respect to pp at the same energy, would be a clear indication
of kinetic equilibration of heavy quarks in the Quark Gluon Plasma.
