And entering into the sepulcher, they saw a young man sitting on the right side, clothed in a long white garment; and they were amazed.
All Commentaries on Mark 16:5 Go To Mark 16

AD 1849
St. Matthew says the angel was sitting on the stone, whilst St. Mark says that they saw him sitting on the right side of the sepulchre. This must not surprise us; for the angel which first appeared sitting upon the stone, might have been afterwards seen by him sitting on the right side of the sepulchre. (Theophylactus)
Perhaps the angel mentioned by St. Matthew is different from the one mentioned by St. Mark. Or it may be understood, that the women entering the monument, which may mean the enclosure of it, saw the angel sitting on the stone, which was placed on the right side of the sepulchre. (St. Augustine)
