Your teeth can fossilise while they're still in your mouth. We call it tartar.

I know there's some animal fossils in New Zealand that date back to its colonization by the ancestors of the Maori, so about the 1400s. Though I don't know if they are partially or fully fossilized.

Where are the bodies?

Another fun fact (dino facts are the best facts): There are more "dinosaur" species alive today than there are mammal species.
11,000 bird species alive today (approx)
6,000 mammal species alive today (approx)

The only interaction I've seen between a T-Rex and a collar is that one scene from The Lost World. Based on what I saw there, I have to assume that collars wouldn't really work for them.

Hi, I was just calling because I live down the street from you, and your daughter come to my house today and she kick my t-rex.

Your daughter come to my house today, And she come on my property and then she kick my t-rex. And now my t-rex needs operation.

From wikipedia: A fossil (from Classical Latin fossilis, lit. 'obtained by digging')[1] is any preserved remains, impression, or trace of any once-living thing from a past geological age.

Answer: yes. It does count. Specifically carbonization.

Personal take: when I think of a "fossil", I think of the stereotypical mineralized bones. Like the T-Rex in the museum of natural history that most people have seen from various movies and TV shows. Thinking of human and human predecessor bones as fossils is just weird to me.
