A dinosaur from the Jurassic period is headed to the auction block. This juvenile Ceratosaurus was discovered in Wyoming almost 30 years ago. It’s 6 feet tall and consists of 139 original fossil bone elements, including a nearly complete skull. Cassandra Hatton from Sotheby’s told reporters the specimen is "one of four ceratosaurus ever found, and the only juvenile amongst them." It’s expected to fetch $4 to $6 million at auction.
