The lot was expected to net between $4 million and $6 million, according to Christie’s.
Instead, it sold for a jaw-dropping $12.4 million on Wednesday.
The 9-foot-long Deinonychus, which roamed western North America, was named for its distinctive and deadly claw on each foot, says the auction house. Deinonychus means “terrible claw” in ancient Greek.
“Shaped like a sickle and held up off the ground when not in use so as to maintain its lethal sharpness, this claw was used to disembowel its prey,” said Christie’s.
