Yes...The sheep have this wooly stuff covering them and whales are wet. Deer bone is found below and behind the antlers.
Seriously, density and shape are the main ways to tell older bones apart. That won't tell a wolf leg bone from a deer leg bone, or walrus from whale, without a lot of experience, but whalebone compared to deer should be obvious.
99% or more of all bone scales on knives and razors are cow bone. ("Buffalo" bone is a type of bovine called water buffalo in Europe. Mozzarella cheese comes from this cow).
