The unexpected discovery was made in the Hallowed Trunks Museum established by 19-century author Dionizas Poška in Šilalė District, Western Lithuania.
It has been thought for years that the bone similar to an old wooden board was part of a mammoth. It was found in local moors. But Professor Linas Daugnora from Klaipėda University and his German colleagues say they have identified that it is a fragment of a whale's jaw, the Lithuanian Television reports.
The bone is believed to have belonged to a blue whale. "The whole curiosity is that this jaw was dug out here, in Bijotai moor. If that's indeed the case, then I would say it's a sensation," Daugnora said.
In his words, if the fact that the bone was found in the local moor, 100 kilometers from the sea, is confirmed, it would be possible to claim that this area was covered with water in the past.
