The loot is always pretty random, and it gets worse with later bosses. Sometimes you can beat the snakeskin boss a dozend times and get only stone plates, sometimes you get snakeskin and a fusion stone or silver key several times in a row.

I've got the feeling the "random" number generator used depends a lot from the system time. If I get a good loot from one boss, there seems to be a very good chance to get another good loot from the next one, with some luck the next two or even three. And if I get only crap, it seems like I better come back some time later instead of getting more crap. (Maybe this is limited to Android, which is known for its bad random number generator...)
