Sorry, typo. I know what detachable jaws are. Ones that are unhingeable and can widen to much greater than usual. I mean just because they usually eat things smaller doesn't mean they won't try to eat larger things. If their jaw got lodged on something large, opening it wider might be the only way out.

I don't. I just mean does thr need outweigh the cost. How much more could rocket launchers offer that Vaxasaurians don't already have through immense strenth and durability. Sure they can get range, but is it worth it from the payoff of the energy and maintenance of the cannon? The answer might be yes, but I feel the odds are weighed against it.

Actually both theories are valid. Because what good is increased chance of reproduction if a creature can't survive to reproductive age? If something is too energy costly and not needed for survival, than they are at a disadvantage as those with less energy expensiture can utilize ebergy for other more important areas. Vestigial things means the feature has been selected against, and the smaller)less functional it is, the less energy it spends. There is a blalance though, like you said if it's not detrimental. If it's not disadvantaging the creature in any way then it can remain even if it's non functional.
