Footprints of a Sauropod, the largest land animal in earth's history, are seen near the Madar village, about 50 km north of the Yemeni capital Sanaa May 22, 2008. Scientists have discovered the tracks of a herd of 11 long-necked sauropods walking along a coastal mudflat in what is now the Republic of Yemen, the first discovery of dinosaur footprints on the Arabian peninsula.
