The skeleton of a 22-metre-long dinosaur¹ (70 feet) fetched six million euros ($6.4 million) Saturday, learned from auction² houses Collin du Bocage and Barbarossa.

An anonymous³ collector snapped up the vegetarian⁴ apatosaurus, which was dug up in the United States, for 4.7 million euros rising to 6 million including costs.

The buyer pledged to allow it to be displayed in a museum.

The skeleton of the giant herbivore is made up of 75 to 80 percent of the original bones and is roughly 150 million years old.

The giant creature’s skeleton, which weighed around twenty tonnes during its lifetime, spent the summer in the orangerie of Dampierre-en-Yvelines, a chateau⁵ some 50 kilometres (30 miles) southwest of Paris, where the sale took place.

Its presale value at auction had been estimated at between three and five million euros.
