As far as I know, sharks can't dislodge their jaws like that. Their detachable jaws serve as a projectile. They "throw" their teeth at their prey, then pull back.

Rocket launchers against a Vaxasaurian's predator can do a lot. You got range and power all in one.

Vestigial does not mean the feature was selected against. It just means it wasn't selected for. If a feature is selected against, it doesn't go past the odd individual who's born with it purely by chance. If a feature is selected for, it spreads across the population like wildfire. If it's neither, it just slowly fades away. Of course, luck is a big factor in this as well. A feature can be selected against and still create an entire lineage, if the individual gets lucky.
