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?

Answer 1

Species don’t stay the same. They evolve and change over time.

That means that although there has been rainforest in Borneo for 130 million years, the plants and animals which make it up have changed over that time.

Some dinosaurs _have_ stayed around, and [evolved into birds](https://www.nhm.ac.uk/discover/why-are-birds-the-only-surviving-dinosaurs.html#:~:text=Birds%20evolved%20from%20a%20group,about%20150%20million%20years%20old.).
