A newly described dinosaur unearthed in Venezuela is a close relative of creatures that later evolved into giant meat-eaters such as Allosaurus and Tyrannosaurus rex. Langer et al. examined two lower leg bones from two different individuals of Tachiraptor admirabilis. The two bones were different enough from those of known species to mark the creature as new. T. admirabilis was a theropod, measuring 1.5 meters from nose to tail. The bones were found in an ancient flood plain, in sediments deposited 200.7 million years ago—less than 1 million years after the mass extinction that marked the end of the Triassic period and the beginning of the Jurassic.
