What type of animal bone + Native American Artifact maybe??

[Ethan J3]

Was looking for fossils in a creek in Florida, and I found a very strange piece of wood that I initially thought was a bone because it was dense/hard. I then noticed there were markings on it that looked unnatural. I’m guessing it could be something Native American but I also know nothing about Native American artifacts. Could someone help me. Also, could anyone id this leg bone and teeth? I’m guessing they are both mammals but I don’t know how to tell which is which, and I’m doubtful either of them are fossilized.

The first item is a piece of bone that has been chewed by a rodent.

Last item looks like part of a deer pelvis.

Hi,

 

I am OK with @Al Dente

 

@Fossildude19 it is an ischium, but knowing which animal it comes from depends on its size, but it is not indicated anywhere here and it does not seem big to me.
