A 70% complete allosaurus skeleton achieved $1.1m at Aguttes auction house in Lyon, France on December 10.

Allosaurus was a powerful predator

The 135m-year-old specimen was the star of a natural history sale.

It was discovered in the Morrison Formation, a layer of fossil rich sedimentary rock that spans several western US states.

It stands at an impressive 2.5 metres tall and 7.5 metres long, with teeth a terrifying 7cm in length (around the size of a paring knife).
