In 1986 I read in a geology book about East Anglia that an iguanodon had been dug up in Potton, the village where I lived. With the huge interest in Jurassic Park and dinosaurs I made it my business to find it. Bedford Museum had never heard of it. They suggested trying the Geological Museum in London. Before I went there I called in at the Sedgwick Museum in Cambridge. Within minutes I was staring at its teeth, bones, claws as well as a host of other fossils unearthed in Potton and other parishes in the second half of the 19th century. It was dug up in a search for coprolite, thought by some at the time to be fossilised dinosaur droppings. That made me want to find out more. Read on and find out what I discovered.
