Plesiosaurs were among the first fossil animals to reach the general public's consciousness through the publication of two imaginatively illustrated books by Thomas Hawkins, a noted collector of fossils: Memoirs of Ichthyosauri and Plesiosauri (1834) and The Book of the Great Sea-Dragons (1840). Using the historical models of his times, Hawkins regarded plesiosaurs as monstrous creations of Satan.
