Detailed description of an event in which associated photoproduction of a charmed meson and a charmed baryon has been oserved. The event was recorded in the course of an experiment using nuclear emulsions exposed to the CERN SPS tagged photon beam and coupled to the Omega Prime spectrometer (Experiment WA58). The proper decay time of the charmed meson, identified as a D0bar, is (0.86+/-0.01)x10^(-13) s while the proper decay time of the charmed baryon, identified as a Lambda_c+ is (0.57+/-0.02)x10^(-13) s
