But since we know that T-rex is the king of the dinosaurs, and that the lion is the king of the animals today. I have 2 questions.
1. Who would be the king of the animals in the Cenozoic Era? (I just realized that we live in this era, in the Quaternary Period while writing this question. So, no modern animals allowed)
2. And who would be the king of the animals in the Paleozoic Era?
I feel like the first question is kinda unorthodox because again, we still live in the Quaternary Period, which means that African lions live along with us in this period and Era.
