Earth shattering dinosaur killer unearthed
Scientists have now discovered the ‘dinosaur extinction layer’ in Montana in the USA, which is a chocolate-coloured strip of rock containing millions of bones.

No one realised that over the millions of years since it hit, any traces would be covered in layers of rock.
