Tracks discovered in Australia's Jurassic Park

SYDNEY - An "unprecedented" 21 different types of dinosaur tracks have been found on a stretch of Australia's remote coastline, scientists said on Monday, dubbing it the nation's Jurassic Park.

Paleontologists from the University of Queensland and James Cook University said it was the most diverse such discovery in the world, unearthed in rocks up to 140 millions years old in the Kimberley region of Western Australia.

Steve Salisbury, lead author of a paper on the findings published in the Memoir of the Society of Vertebrate Paleontology, said the tracks were "globally unparalleled".
