The 11ft tall and 20ft long fossil, nicknamed Apex, could fetch up to $6m as it’s celebrated as ‘one of the best unearthed’

The largest and most complete Stegosaurus fossil ever found is expected to fetch up to $6m (£4.7m) when it is sold as the star lot in Sotheby’s “geek week” auction this summer.
