Well actually it was found 6 years ago, but sometimes you come across news that just make you smile . A 110 million old creature which was preserved not only as bones or flattened fossil, but 3D.National Geographic said:Some 110 million years ago, this armored plant-eater lumbered through what is now western Canada, until a flooded river swept it into open sea. The dinosaur’s undersea burial preserved its armor in exquisite detail. Its skull still bears tile-like plates and a gray patina of fossilized skins.
As a side note the fact this is a new species previously unknown to science just shows that we really don't have anything more than a little glimpse to the diversity that was Earth back in the day.
