The largest piece of Mars ever found on Earth has sold for just over $5 million at a Sotheby's auction in New York.

The largest piece of Mars ever found on Earth was sold for just over $5 million at an auction of rare geological and archaeological objects in New York on Wednesday, while a juvenile dinosaur skeleton went for more than $30 million.

A rare Mars rock and a young dinosaur skeleton were sold at a New York auction. The Mars rock, found in the Sahara, fetched over $5 million. The dinosaur skeleton, a Ceratosaurus, sold for over $30 million.

The red, brown and gray hunk is about 70% larger than the next largest piece of Mars found on Earth and represents nearly 7% of all the Martian material currently on this planet, Sotheby’s says. It measures nearly 15 inches by 11 inches by 6 inches.

An auction in New York City featured rare geological artifacts, including the largest piece of Mars sold for $5.3 million and a juvenile dinosaur skeleton that fetched over $30 million, marking it as the third-highest amount paid for a dinosaur at auction.

An exceptionally rare Martian meteorite has been sold for £3.2 million at a Sotheby’s auction in New York after being discovered in the Sahara Desert. Weighing 24.5kg (54lb), the meteorite—named NWA 16788—is the largest known fragment from Mars ever found on Earth.
