Partial skeleton of a crocodile's head was found 14 feet below ground level in Morrelganj upazila of Bagerhat yesterday.
Workers found the skeleton while excavating an ancient pond named Dibraj Dighi in Panchakaron village of the upazila.
According to locals, the dighi (large pond) is one of the around 360 such ponds built in Bagerhat during the reign of Muslim ruler and preacher Khan Jahan Ali, who was known to have released crocodiles in the ponds.
The skeleton unearthed yesterday might be of a crocodile from that period, they also said.
Confirming the unearthing of the skeleton by workers, Panchakaron Union Parishad Chairman Abdur Razzak said it was handed over to the upazila nirbahi officer (UNO), who will send it to archaeology department.
UNO Kamruzzaman said the skeleton will soon be handed over to the Department of Archaeology.
