In a sample of 467×106 BB̅ pairs collected with the BABAR detector at the PEP-II collider at SLAC we have observed the decay B̅ 0[beta superscript -0]→Λc+p̅ π0 [delta subscript c superscript +]p[superscript - pi 0] and measured the branching fraction to be (1.94±0.17±0.14±0.50)×10[superscript -4], where the uncertainties are statistical, systematic, and the uncertainty on the Λc+ [delta subscript c superscript +]→pK-π+ [p kappa superscript - pi +-π+ branching fraction, respectively. We determine an upper limit of 1.5×10[superscript -6] at 90% C.L. for the product branching fraction B(B̅ [superscript 0]→Σ [sigma subscript c superscript +](2455)p̅)×B(Λ [delta subscript c superscript +]→pK-π+ [p kappa superscript- pi +]). Furthermore, we observe an enhancement at the threshold of the invariant mass of the baryon-antibaryon pair.
