Photo: First Dinosaur Tracks Found on Arabian Peninsula



Footprints recently discovered in Yemen (above, in an undated photo) suggest a herd of plant-eaters were on "leisurely stroll" about 150 million years ago, experts say.

The rare find may spark debate, since the two types of herbivorous dinosaurs that left the tracks—ornithopods and sauropods—were not thought to mingle.
