I bought this bone fragment for $10 and it said that it came from a discovery of a badly degraded skull of a tyrannosaurus. It is from the Hell Creek Formation and I was wondering if anyone could confirm that it is from a tyrannosaurus, or from something else
My only direct experience with dinosaur bones was on a tour of the Gobi desert. We were told if you licked a rock and it stuck to your lip it was a dinosaur bone, if not it was a stone. So we spent the afternoon in the desert licking stones.
