I live on the west coast of Sweden where I spend a lot of time in the archipelago. Last week I found a very strange bone among some stones on a small island. There were no other bones around indicating the species of the animal and I have never seen anything like it. My first thought was a jaw-bone but there are not even a hint of teeth and the angles as well as the “construction” are looks strange for a jaw bone as far as I can judge. On the rounded end there is some kind of “buildup” that could be interpreted as belonging to a kind of joint. This makes me think in terms of a hip or pelivis bone but after spending a lot of time on Google it does not make me any nearer a solution. Any help with the identification is appreciated! Measure in centimeters.
