Rock or Animal Bone Fossil?

[peppzoe]

Hi Everyone ~

 

This rock/bone/mineral was found in Rock Creek on our private land in Wisconsin. The creek is located in a heavily wooded area where there's zero foot traffic & a very diverse wildlife population.  Bear, badgers, cougars, fisher cats, etc.  The water is shallow and has numerous sandy mounds & outcroppings, that are full of rocks & minerals, just as the  name implies.  This rock was in a pile of pitch black stones and caught my eye because of the rusty red color & unusual shape.

 

Historically speaking, millions of years ago, our land was part of a shallow inland sea.  According to an Ice Age map, during the Pliestocene Period,  much of the state was covered by the Wisconsinan Glacial Ice Sheet.  However, the location of our land was actually situated in what is identified as a "driftless area".

 

Thousands of years later, after the ice melted, Native Americans lived and hunted on these grounds.  A farmer up the road from us found several Native American artifacts ploughing his field, so I'm always digging and searching for relics of any kind.  

 

This rock (or bone) caught

my eye, because it was lying in a  pile of pitch black stones.  One side has a thick brown sandstone coat that measures up to 1.9cm (.75") in some places, while the other side has a thin layer of rusty red sandstone or sedimentary rock.  There's a lot of red granite on the land.  The rusty red color of this rock, is really close to the shade of numerous granite stone on the land.

 

There are small spots of chalky white substance that have the characteristics of bone under magnification, but they are so small that it's hard to tell.   Also, there's a small circle, and finger mark impression on the sandy side.  Actually the shape reminds me of a T-Bone steak.  

 

The measurements are approximately 16.5 cm (6.5") long by 10.16cm (4") wide, and has a thickness anywhere from .66cm (.25") to 1.9cm (.75").  

 

Any suggestions are greatly appreciated.  Thank you for your time!  My apologies for the long post.
