Hello, Yesterday I was walking my dog on Marazion beach in Cornwall and she sniffed out this bone structure, none of us can decide what it was from, guesses are a cow hoof a giraffe hoof a seal flipper a crab claw and the st michaels mount giants foot! (Bless!) from a wide range of age people. I wish I had put something next to it now but it was bigger than my size 8 foot. What animal/mammal is it from? Thank you very much.
This is interesting, it is part of the flipper of a dolphin/whale. The single bone on the right of the picture is a humerus with the articulation for the shoulder facing you. The other two parallel bones on the left are the Ulna and Radius, they are both broken in half. Now a size 8 boot is about 30cm long so these are quite big. A Minke whale would be just a little bigger than this so my guess would be pilot whale.
