    Twenty eight species of oviparous chondrichthyans were reported on the Argentine Continental Shelf (SW Atlantic). The egg cases laid on the sea bed provide useful information to identify species, eggs laying areas and seasons. Based on the analysis of 155 egg cases corresponding to 21 chondrichthyan species, an illustrated field guide for a correct identification is presented.
