Was just packing up to go into town on errands, but wanted to let you know you posted them right! They are terrific pictures and places, as usual!
I’d say the bones are somebody’s pelvis, but without scale and other hints, I have no idea what!
DING...DING...DING...We have a winner ladies and gentlemen. It's a cow's pelvis.
I found one of these at my granddad's place out in the country when I was a kid and, being a city kid, I had no idea what it was but it looked like a mask to me, so I carried it home with me, and my poor Mother, bless her heart, let me. Every kid in the neighborhood got to play with it for like a week before the novelty wore off. And yes, I was a strange kid! ;o)
