No, only from fossils
if you go into the desert ruins on route four there will be a man with a backpack standing in front of a staircase talk to him, he'll tell you that his pack is really heavy he'll then offer you a choice of a wing fossil or the fossil that turns into tirtouga. take your pick and then go to the nacrene city museum. take the fossil to the lady on your left and she'll turn it back into a Pokemon. hope this answers your question.
