First, warranty. Depending on your shop, that's a 50/50 proposition. They'll say you broke it, and its up to you to convince them otherwise. Good luck.
Hard to tell from the pics but its likely only the topless layer is broken as this seems to be the weakest link in the pigs' build. In this case, use marine epoxy to seal the wound and finish with stickers.
If the damage is deeper, you could probably see laminates peeling when flexed by hand. But I doubt this is the case, judging by your description. Have a technician take a look if you are not sure.
