Assuming the translated text is correct, you get to play them directly to the Bench. But it's not for free -- it ends your turn, which is a pretty hefty price to pay for just 2 Fossils, unless they end up being pretty good.
At the moment is does make Trainer Lock slightly more realistic -- with Kabutops Active and Omastar in the back, as long as you've got less Pokemon in play than your opponent you'll be blocking both Items and Supporters (although just Omastar alone is probably more realistic). Baby Aerodactyl can also be played directly and does 180 for [C][C][C] if you have no EX/GX in play, and yes, it's eligible for Triple Acceleration Energy because it's a Stage 1.
And that's before we even know what Fossils this set has in store for us!
