Photo: Dinosaur "Dance Floor" Found in Arizona



Geologist Winston Seiler points to what he believes are dinosaur tracks, found recently in a remote site in Arizona.

The impressions once were thought to be potholes eroded by water, but Seiler and colleague Marjorie Chan claim in an October 2008 study that the holes are evidence of a dinosaur "dance floor" where several types of dinos congregated.
