COVER Massive thumb (33 centimeters along outer arc) and smaller third claw from the hand of an ~11-meter-long dinosaur that was recently discovered in the remote Ténéré Desert of the Niger Republic. This sail-backed predator apparently used its long, narrow snout to capture fish along the banks of broad rivers around 100 million years ago. See page 1298.
