Therizinosaurus

In 1948, several giant claw bones were found by a Soviet-Mongolian scientific team and because the shape of the claws is similar to the claws of some turtles, workers first thought they belonged to a giant turtle, so the specimen was named Therizinosaurus cheloniformis ("turtlelike scythe reptile").
