  The locally observed cosmic ray spectrum has several puzzling features, such
as the excess of positrons and antiprotons above $\sim 20$ GeV and the
discrepancy in the slopes of the spectra of cosmic ray protons and heavier
nuclei in the TeV-PeV energy range. We show that these features are
consistently explained by a nearby source which was active $\sim 2$ Myr ago and
has injected $(1-2)\times 10^{50}$ erg in cosmic rays. The transient nature of
the source and its overall energy budget point to the supernova origin of this
local cosmic ray source. The age of the supernova suggests that the local
cosmic ray injection was produced by the same supernova that has deposited
$^{60}$Fe isotopes in the deep ocean crust.
