Ancient Creatures Scarier Than Dinosaurs

Are there many who know what was BEFORE the dinosaurs? What animals lived 100 million years before them? Or what fearsome beasts lived 50 million years after them?
We bet there are far fewer experts here.
But there must have been some creatures living on the planet at those times, right?
And some of those creatures were scarier than the dinosaurs. If not in size, then in appearance.

What ancient fish had a bite force twice stronger than a modern polar bear?
What ancient bird had a wingspan almost as large as an F16 fighter jet?
What monster had the body of a bull and the head of a boar?
And many more interesting things!
