Footprints in the sands of time


In the upper Jurassic the Yorkshire coast alternated between a vast delta and an aluvial plain. During one of the aluvial plain episodes a Dinosaur strode over a sandbank, little realising that 150 million years later the tracks of its passing would be revealed again.
The footprints were made in poorly sorted fluvial sand which was compacted under and around the footprints. The overlying argillaceous sandstone is being selectively eroded leading to the footprint trail we see today.
Five separate prints can be seen in this picture, each a metre apart.
