I am forever grateful to all the geologists and fossil-hunters who I have met during my life and have shared their knowledge and experience with me. In particular I owe a lot to the lecturers and technicians at the former Geology Department of the University of Hull and all the members of the Hull Geological Society; especially Felix Whitham for introducing me to the Yorkshire Chalk, Lynden Emery for introducing me to the Speeton Clay and Ron Harrison for his pioneering enthusiasm in urban geology.
