Sixty-one short-beaked common dolphins were found washed up in Puerto Madryn, an Argentinian city in northern Patagonia.
According to local authorities, 49 of them died on the coast of the El Doradillo Protected Natural Area while 12 were returned to the sea alive.
A couple walking around the coastal area noticed an unusual number of birds on the beach and investigated.
When they saw they were pecking at scores of dead dolphins lining the shore, they immediately called emergency services.


The operation was headed by Mariano Coscarella and Silvana Dans, two scientists from the Marine Mammal Laboratory for the Study of Marine Systems.
Coscarella explained: 'We have a protocol in place and local authorities are helping us with the logistics.
'First, we will store the dead specimens and then start an investigation into their deaths.

Secretary of Protected Areas Nestor Garcia said: 'It has been a very sad morning. Fortunately some dolphins were saved.
'After speaking with specialists, I can say that there has been an increased presence of killer whales in the area but we do not yet know if that is a cause.
'We will have to wait for the results of the investigation.'
