In this photo taken Wednesday, Oct. 22, 2014, study lead author Lee Yuong-nam, director of the Geological Museum, speaks to the media about Deinocheirus mirificus during a news conference in Seoul, South Korea, Wednesday, Oct. 22, 2014. Nearly 50 years ago, scientists found bones of two large, powerful dinosaur arms in Mongolia and figured they had discovered a fearsome critter with killer claws. Now scientists have found the rest of the dinosaur and have new descriptions for it: goofy and weird. That's Deinocheirus mirificus, which means "terrible hands that look peculiar." It is newly reimagined after a full skeleton was found in Mongolia and described in a paper released Wednesday by the journal Nature. Some 70 million years old, it's an ancestral relative of the modern ostrich and belongs to the dinosaur family often called ostrich dinosaurs. (AP Photo/Lee Jin-man)
