ELI5: Why have we found so many more dinosaur bones from hundreds of millions of years ago than our ancestors from over 40,000 years ago?

Ancestor's bones*** 

I'm not asking why we have found more than our ancestors found.

This is really interesting! Thanks for giving more than just the obvious answers and also points as to why it's not even really a factual question necessarily!

Dinosaurs were around for about 165 million years, and a lot of them were *huge*.

The genus *Homo* is only a few million years old, and *Homo Sapiens* have only been kicking around for about 200,000 years. Compared to dinosaurs we are tiny, and haven't been around for very long at all. Which makes our fossils a lot scarcer than theirs.
