My creature is a B.O.W, designed to be especially good at ambushing and to use its Jaws as it's main weapon. It's basic hunting strategy is similar to the spectral bat's, immobilizing prey and delivering a bite to the skull to kill it. Additionally, it also possesses a ranged blasting attack from its mouth (supplied by mechanical enhancements inside its chest, no need to enter in the dragon breath matter), but that's secondary. this image is merely illustrative of how I'd like the jaw to be able to move.

However, observing cases like crocodiles and the T-rex, it appears that their bite force seem to be linked to a lack of mobility in the skull,usually meaning lateral jaw articulation is minimal. The jaw being split also means each half of the lower jaw would need to have all the muscles necessary for the range of movement without being Able to rely on one another's.
Based on this, could the B.O.W keep the necessary bite force, while having a splitting lower jaw, by earth standards? Would it need something like the Dunkleosteus' plates near its head to accommodate such musculature?
Note: the creature is roughly 2m tall, weights around 200 kg and is a good climber, usually surprising prey by dropping on it. It's main target consists of humans (which is why it needs powerful bite). Going for the neck is a secondary strategy, should the head prove to be too heavily protected, but not its main strategy. The creature has an ideal bite force of around 5000 newtons (I planed to use bony plates as dentition, since they'd help minimize the contact surface and concentrate the force in a piercing/shearing activity), more that what's required to bite through a human skull through the temples. Ideally it needs to be able to keep its mouth properly shut when not in use. It's skeletal system is an endoskeleton.
