This dinosaur met its death as it was trapped in a sticky lime lagoon. It lay motionless, as the salty low-oxygen water was lethal to any scavengers who may have disturbed its position.
The unique mud in which it lay could capture impressions with unusual detail. It recorded the imprints of soft bodied organisms such as jelly fish and even the movement, a trail, of a horseshoe crab. Because of this, after millions of years, we are able to see that the dinosaur had feathers. A bird!
The bird appears to be ‘spread eagled’, ‘ splayed’ and ‘flat like a roadkill.’*
The limestone is ideal for printmaking process, lithography. Being smooth and fine it is able to print great detail and breaks off from the quarry in thin white slabs.
