Parasaurs aren't the best of choices for dinos. but if you stat them right there pretty good for raptors and dilos.the best way to stay them is 1k health 2k stamina 300 movement speed 1k weight and 250 melee damage. What ever level ups left I would evenly disburse them between health stamina and melee till melee is 300 then any level ups after melee is 300 they could go in movement speed
