"The park authorities were summoned to investigate the death of the elephant and to remove the canines. The park authorities found no trace of human attack on the elephant," the photos said.
The accident occurred in the South Luangwa National Park in Zambia earlier this month, it said.
Experts believe that the elephant was injured when the crocodile was chasing him, and then collapsed and fell on him as he tried to crawl towards the river.
Crocodiles usually attack small, sick or infected elephants.
