Borealopelta

Borealopelta was a large armoured dinosaur. It was found in Alberta, Canada and is a nodosaurid ankylosaur. 

The osteoderms in its armour were in their life positions, with remains of their keratin sheaths and overlying skin. It may be the most complete ankylosaur ever found. Melanin found in its epidermis remains suggests it was camouflaged.Gabbott, Sarah 2017. Armoured tank-like dinosaur used camouflage to hide. BBC Science & Environment. Brown, Caleb M. et al 2017.

The report gives its estimated length as 5.5 metres and its estimated weight as about ~1,300 pbs.The discovery and work on Borealopelta.
