In a river 25km from beach.. Well it looks like a huge skull to me, its 60cm long. And I am probably wrong. How ever this river feels fossilferous. the area is registered as pachna formation (miocene 5-23million years)
I will attach also a photo of what looks like a piece of wood or bone. Its 1m long and it is found nearby the skull-like piece. They are too heavy to move but if u find any of those interesting I can go there and make more photos thanks
