Never ever let your carno loose on a parasaur when these guys are in the area!! These guys can throw mud/poop (can't really tell when it is covering my face) but if you tame them they can throw boulders.
When you tame a chocolate knuckle horse watch which attack you do. The rock throw does massive damage, but is really slow. The main attack has tremendous knockback and can be used to keep most things at bay whilst doing damage
When living near Chalicotherium spawn points, it is best to have a rex or strong dino on neutral following a random dino where you want it so if a Chalicotherium attacks, your base will be defended. If you are on a tame free world or dont want to risk your dinos, use torrents or xplants.
