Wait hold up, I thought megalodon had the strongest bite force of any fish? It says here that Megalodon has a bite force of 110-180,000 N while here it says that Dunkleosteus has a bite force of about 6-7,000 N.

3.Name 3 transition fossils on the list and between which two groups of animals they are(sorry for the bad wording)

Actually, I think you're right. I just saw some articles at one point saying Dunkleosteus did, but it looks like they're pretty old so they probably aren't relevant. Nice catch

1. Isotelus
2. Dracorex, some think they are simply young Pachycephalosaurus
3. Archaeopteryx (dinosaurs to birds), Tiktaalik (fish to tetrapods), Messohippus? (hyracotherium to modern horses)
