Nigersaurus taqueti, a 110 million-year-old sauropod from the Sahara, recreated in the flesh by artist Tyler Keillor in collaboration with Paul Sereno at the University of Chicago. The flesh model stars in an exhibit at the National Geographic Museum at Explorers Hall through March 18, 2008.]]>

Nigersaurus taqueti, as it looked in the flesh. Paleontologist Paul Sereno’s research suggests the animal mowed down ferns and other plants with its lightweight skull and skeleton.]]>
Nigersaurus taqueti, in the flesh and without. A flesh model of the animal’s skull and neck as well as a life-sized, 30-foot-long (9 meters) reconstruction of the dinosaur will be on display at the National Geographic Museum at Explorers Hall through March 18, 2008.]]>
Nigersaurus taqueti grew to a length of some 30 feet (9 meters), with a hip height of 8 feet (2.4 meters) and a weight comparable to an elephant. Paleontologist Paul Sereno and his teams collected about 80 percent of a skeleton of
