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

No. Flora is much more resilient than fauna, that’s why plants were on land before the animals followed them. Fauna are very sensitive to changes in environment, and a 10 km asteroid impact is definitely enough to kill any megafauna anywhere on Earth, and it did.
