We report new measurements relative to charmed hadron spectroscopy and measurement of charm hadron properties by the LHCb collaboration. Two new Xic0 baryons are observed, and the lifetimes of the Lc+, Xic0 and Xic+ baryons are measured with greatly improved precision compared to the current world average. The doubly Cabibbo-suppressed decays of Xic+->p phi and Xic0->Lc+pi- are observed for the first time. The most precise measurement of Xicc++ mass and production ratio is performed. Finally, the Xicc+ baryon is searched for in the Lc+K-pi+ final state.
