Child me hated this scene. There's no way a triceratops could take a dump that big, I would tell anyone who would listen. Finding out the real velociraptor was just a pissed off turkey didn't help things either.
I always assumed they'd drop perfectly spherical shit orbs, the kind of feces you'd expect an enormous rabbit or hamster to produce. But that's just me. I guess we'll never really know the truth.
