I probably should have done Carcharodontotitan's requests first, but I'm still trying to get a composition that works right. Meanwhile, here's Zimices's request for Palaeophis vs Zygorhiza. The snake has coiled around the mother's calf, and she doesn't want her son to be devoured.
Very nice scene! But I don't think Palaeophis would have been able to coil itself around the calf. Besides, as this is only the calf, Palaeophis would have probably been much larger.
And maybe it's a subadult. Or a very big calf.
That could be of course, but remember even adult Zygorhiza's get only six meters in length at maximum, while Palaeophis might have been more than ten.
Nice, love the scene, although I don't made this request...
