Made trips on the flop, lost to a turned fullhouse

$35+$3 satelite to Scandinavian Open. I didn't know much about villain, because he had just joined my table. In the previous hand he made a runner runner straight flush to stay alive (he flopped a low flush and faced a higher one but turn and river helped him).

I've only called the flop as I was almost sure he would bet quite a lot on turn when I check it. This was probably a mistake. A raise to 500 would probably win a hand for me and I wouldn't lose to his turned fullhouse. Any comments?
