Did ancient wildfire end in barbecue?
Small pieces of large bones and petrified wood that show distinct signs of being burned may be evidence of a 74-million-year-old wildfire in central Wyoming.

Fossil Fingerprints: Rare earths tie bones to burial ground
The soil in which fossilization occurs leaves a chemical imprint on the bones, suggesting that scientists can use this soil signature to identify more precisely a fossil's original home.
