Mammal Tooth? And Unknown

[XceeD]

These fossils were given to me so I have no clue where they are from. It would be interesting to know what they are/what animal they came from. The tooth is a little over two inches in length. I have absolutely no idea what the second fossil is. Any help is appreciated and thank you to those who attempt to identify them.

The tooth appears to be a frament of a domestic pig tooth, the rear portion of m3.

Looks like a pretty good match, thanks for the help. Any idea what the 2nd fossil is?

The other one looks like it might be a crushed crinoid calyx, or maybe some other kind of echinoderm. The larger pentagon shaped piece is what leads me to believe this.

Other than that, it may be a crushed shell, maybe from a brachiopod.
