  • What's new in exploration

    Perry A. Fischer, Engineering Editor

    A team led by University of Chicago paleontologist Paul Sereno, a National Geographic Society Explorer-in-Residence, has made a remarkable fossil discovery: the skull of Sarcosuchus imperator, nicknamed SuperCroc. The behemoth’s skull was found in the Cretaceous El Rhaz formation in the Tenere Desert of Niger, a part of the Sahara. The giant African crocodile lived 110 million years ago. The monster’s skull was nearly 6 ft long, it measured up to 40-ft long and its torso was 5 ft in diameter. Weighing almost 18,000 pounds, it could easily chomp down small dinosaurs. SuperCroc was covered head to tail with bony-plate "scales," each one showing growth rings. Using these rings, the Sereno team estimated they grew throughout a 50 – 60 year lifespan.
