Eli5 how come we have so many fossils of specific animals?

I’ve heard that 99% of animals won’t fossilize and the ones that do are rare to even find, if that’s the case then how come we have so many examples of specific species even across the world from eachother when surely the fossil record should just be a jumbled mess of at least only quasi related species, is it that some species are lumped together due to similarities or what?

So there’s about 4,000 mostly..ish full skeletons of dinosaurs out there.

Dinos were on earth for 165 *million* years.

So that’s about one full fossil every 40,000 years that dinos existed.

Modern humans have existed for about 200,000 years.

So that would be like finding 5 human fossils. Total ove the entire time humans have been around.

Yeah, we have found a lot of fossils. But there were 100s of billions of not trillions of dinosaurs out there.

It *is* a jumbled mess. We have identified some 700 species of dinosaurs. There we’re likely millions of them.
