In January 1983, an amateur fossil hunter named William Walker came across an enormous claw sticking out of the side of a clay pit - Smokejacks Pit at Wallis Wood, Ockley near Dorking in Surrey (United Kingdom).
Many important fossils have been found in the sandstones and clays of the Weald, including, for example, Baryonyx.

Lurdusaurus was contemporaneous with the bizarre large theropod Suchomimus, which some believe to be synonymous with the slightly earlier Baryonyx from England, and with the sympatric Ouranosaurus, notable for its tall-spined vertebrae.
