Thousands upon thousands of dinosaur bones/fossils have been found and not one instance where any human bones/fossils have been found with them or in the same layer. Unless you look for photoshop pics and weird youtube videos by messed up people.
There are examples of human foot prints in the same layer as dinosaur foot prints. And most certainly fossilized human remains have been found.
If you take the "catastrophic extinction event" that forms fossils. To get fossils requires lots of water, lots of dirt and to be compacted in a very short span of time. (That the objects buried don't have time to decay as they normally would have if they had not been buried in such a matter.)
A washing of an ocean over a basically flat land mass, would leave scattered pockets of plants and animals "mixed together"; yet only from a generalized place of their "original location". And obviously those of largest mass would settle to the bottom first. The fossils are formed and then there are earthquakes and volcanos that rearrange some of these rock layers.
In some rock layers, fossils aren't found at all. Which could have been land uninhabited (a desert maybe) or deposits of silt and smaller sand particles that eventually settles out after the larger things have already been deposited.
So if you have dinosaurs in one bio environment and humans pretty much living in a different place (Noah's flood implies human populations having been congregated in "cities".) You would not necessarily see large quantities of the two "mixed together". Once the initial wave of water had passed, what ever from which ever individual environment is deposited together. And smaller portions from one bio environment to another may be deposited on top of ones that first settled. This is why they find deposits of sea life in unexpected places.
Imagine if you were looking at North America in 1400 AD. You'd have pockets of human settlement within swaths of expansive forest. If you were to throw a giant wave over North American, you'd find large deposits of forest life with very few humans because the bulk of human populations don't generally live "in the wild". And like wise, where you'd find human deposits would be greater percentage of human remains.
This does not mean though that there were not humans who lived in the wild. (Or in the case of the sets of tracks found - humans who hunted dinosaurs.) So looking in a fossil deposit; you could expect to find 10 thousand dinosaur fossils in copious layers before you found one human mixed in with them.
Now also we need to take into consideration the size of the human population as opposed to the size of the animal populations. If you believe Genesis; we start with two humans. Of the animals created though; there were multiple individuals of a "kind" to populate the earth. So, their population numbers are going to expand that much faster, because there are more of them to begin with.
So thus one explanation as to why there are that many more fossilized animals than humans.
