A triceratops skeleton is expected to fetch 500,000 euros at an upcoming Christie’s auction in Paris, where giant shark teeth and a sabre-toothed tiger skull are also up for bids.

The skeleton of the three-horned dinosaur, from a private European collection, is the highlight of the April 16 auction. It will mark the first time that such a dinosaur specimen goes up for public sale since a T-Rex called “Sue” was sold in New York in October 1997.

The four-legged triceratops, which dates back between 65 and 67 million years, measures 7.5 metres in length and bears a large bony frill and three horns.

In what is said to be a historic sale, a 101-carat, near-flawless diamond will go under the hammer later this year in Hong Kong, media reported Wednesday.
