No megalodon obviously, because it is too big for the aquarium to showcase it. (Sorry for that.)

I am between Hybodus and Helicoprion. But I am going for the devil horned shark.

No Xenacanthus >:(

Cretoxyrhina is the best extinct Shark, fight me

HYBODUS SWEEP

Helicoprion better

Wrong

Imagine only having one stupid set of teeth to go off of and not an entire skeleton
