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.
The beast probably lumbered along on two legs like a cross between TV dinosaur Barney and Jar Jar Binks of Star Wars fame. It was 16 feet tall and 36 feet long, weighing seven tons, with a duckbill on its head and a hump-like sail on its back. Throw in those killer claws, tufts of feathers here and there, and no teeth and try not to snicker.
And if that’s not enough, it ate like a giant vacuum cleaner.
That’s Deinocheirus mirificus (DY’-noh’-KY-ruhs mur-IHF’-ee-kuhs), which means “terrible hands that look peculiar.” Some 70 million years old, it’s an ancestral relative of the modern ostrich and belongs to the dinosaur family often called ostrich dinosaurs.
“Deinocheirus turned out to be one the weirdest dinosaurs beyond our imagination,” study lead author Yuong-Nam Lee, director of the Geological Museum in Daejeon, South Korea, said in an email.
Evolution isn’t always what we think When scientists in 1965 found the first forearm bones nearly 8 feet long many of them envisioned “a creature that would strike terror in people,” said University of Maryland dinosaur expert Thomas Holtz Jr, who wasn’t part of the study. “Now it’s a creature that would strike bemusement, amazement.” And yes, he said, “it’s pretty goofy.”
Lee figures the tilted wide hips and massive feet show that Deinocheirus was a slow mover and probably grew so big to escape from being regularly feasted on by bigger dinosaurs.
It had a beak that could eat plants, but it also had a massive tongue that created suction for vacuuming up food from the bottoms of streams, lakes and ponds, Lee wrote.
