The world's deepest dinosaur finding - 2256 metres below the seabed

While most nations excavate their skeletons using a toothbrush, the
Norwegians found one using a drill.
The somewhat rough uncovering of Norway's first dinosaur happened in the
North Sea, at an entire 2256 metres below the seabed. It had been there for
nearly 200 million years, ever since the time the North Sea wasn't a sea at
all, but an enormous alluvial plane.

It is merely a coincidence that the remains of the old dinosaur now see the
light of day again, or more precisely, parts of the dinosaur. The fossil is
in fact just a crushed knucklebone in a drilling core - a long cylinder of
rock drilled out from an exploration well at the Snorre offshore field.

Norway's first dinosaur fossil is a Plateosaurus, a species that could be
up to nine metres long and weigh up to four tons. It lived in Europe and on
Greenland 210 to 195 million years ago, at the end of the Triassic Period.

The Plateosaurus at the Snorre offshore field had a hollow grave. The
fossil, which was found 2256 metres below the seabed, represents the
world's deepest dinosaur finding. But it is by no means certain that the
record-breaking knucklebone is a rarity down there in the abyss.

In fact, the old North Sea land was once a huge area where big rivers
meandered through dry plains. Now the landscape has been compressed to form
a pattern of fossil alluvial sand between banks of red shale.
