Thanks. Interestingly, this is the first large fossil like this that Suncor had run across, in all the digging they had done up in the oil sands. And as you can imagine, finding a land animal like this nodosaur in the middle of what would've been a shallow sea is extraordinarily unlikely. Other mining companies have found other fossils in similar formations, though usually of non-dinosaur marine reptiles (e.g. http://www.sciencemag.org/news/2016/10/ancient-sea-monster-b...).
