US geologists discover 'dinosaur dance floor'
(Agencies)
Updated: 2008-10-21 12:05  This undated photo released by the University of Utah shows a trackway, or set of prints made by the same dinosaur, as it walked through a wet, sandy oasis some 190 million years ago in what is now the Coyote Buttes North area straddling the Utah-Arizona border. University of Utah geologists published a new study published in the October issue of the science journal Palaios showing that numerous impressions at the site are dinosaur tracks, not erosion-caused potholes as was believed previously.
