Eli5: If the rainforest of Borneo is 130 million years old, why aren’t any surviving dinosaur species found there?

Question

If old rainforest ecosystems like these could withstand extinction events (ie. Asteroid impact), wouldnt the fauna living there survive too?

In: 575

Answer 1

Lets turn this question around. Imagine there’s a man living in the woods alone. He hunts, he fishes, he gathers berries, he makes clothes out of skins and plat fibers. A real survivor man. Now you go into the forest and shoot him in the head. Why is the forest still there?

Just because the forest is still there doesn’t mean that certain inhabitants have not been killed.

The changing conditions of the time favored smaller animals.
