The pachyderm could not be saved despite all efforts by experts, Divisional Forest Officer (Baripada) Sanjay Swain said.
Veterinary surgeons and experts from Nandankanan Zoo in Bhubaneswar, Odisha University of Agriculture and Technology and Similipal Tiger Reserve tried their best to save the animal, he said.
The pachyderm was tranquilised and pulled out of the 30-feet deep well, in which it had fallen, with the help of a heavy crane near village Dubuasahi under Dukuda range of Baripada forest division yesterday, Swain said.
A postmortem on the elephant would be conducted tomorrow, he said.
