  We present the ground and excited state spectra of singly, doubly and triply
charmed baryons by using dynamical lattice QCD. A large set of baryonic
operators that respect the symmetries of the lattice and are obtained after
subduction from their continuum analogues are utilized. Using novel
computational techniques correlation functions of these operators are generated
and the variational method is exploited to extract excited states. The lattice
spectra that we obtain have baryonic states with well-defined total spins up to
7/2 and the low lying states remarkably resemble the expectations of quantum
numbers from SU(6) $\otimes$ O(3) symmetry. Various energy splittings between
the extracted states, including splittings due to hyperfine as well as
spin-orbit coupling, are considered and those are also compared against similar
energy splittings at other quark masses.
