Armoured tank-like dino used camouflage to hide

The exquisite specimen is a type of amour-plated nodosaurid ankylosaur. It was camouflaged which suggests that, despite its tank-like appearance, it hid to avoid predation. That such a large creature needed camouflage indicates the presence of even larger, keen-eyed meat-eating theropod dinosaurs. A new species of dinosaur named Borealopelta markmitchelli has been discovered from an oil sand mine in Alberta, Canada, and is described this week in Current Biology.
