  Different scenarios of baryogenesis are briefly reviewed from the point of
view of possibility of generation of cosmologically interesting amount of
antimatter. It is argued that creation of antimatter is possible and natural in
many models. In some models not only anti-helium may be produced but also a
heavier anti-elements and future observations of the latter would be critical
for discovery or establishing stronger upper limits on existence of antimatter.
Incidentally a recent observation of iron-rich quasar may present a support to
one special model of antimatter creation.
