Big John, largest known triceratops skeleton, goes on display before auction

Bones found in 2014 in what is now South Dakota described as miracle of nature and work of art'

In its time, approximately 66m years ago, the triceratops, with its massive collared skull and three attacking horns, was one of the most dangerous and daunting of dinosaurs.

Now the remains of one of the giants of the Cretaceous period, a herbivore despite its fearsome appearance, have gone on display in Paris before they are auctioned next month.
