Found these sticking out on the edge of a pond about a foot below the top of the ground. It appears to be the upper limbs, front and back, of a mammal. There are very robust.
sounds right....this area is now a suburban park but was either pasture/farmland or just open space as late as the 40's. So maybe a hog slaughter? There were a vertebra and one rib bone there also.
Look like pig bones, rear (ham) & front, (shoulder)
Below is shoulder bone (top in photo) I found with Knife remains, note hack marks,
Good Day, Herbie
