Reptile Mosasaur Tooth

Mosasaurs had long heads, strong and flexible necks and hydrofoil-like limbs. Their large jaws had stabbing teeth and had a hinge in the mid-lower jaw similar to modern day constrictor snakes. This enabled them to swallow huge prey. The teeth of mosasaur were deeply lodged into the jaw-bone. This tells us that there was huge power in the bite to necessitate such well-anchored teeth. 

Please note that every Mosasaurs tooth will be slightly different from the one shown in the images.
