The Apatosaurus skeleton will become the world's largest dinosaur ever to be auctioned when it goes under the hammer at Chateau de Dampierre-en-Yvelines on November 16, 2024. More than 20 meters long and composed of 75 to 80% of the original bones, the imposing specimen is the largest dinosaur ever auctioned, for an estimated price between 3 and 5 million euros.
