Trap Street and Dinomania

In 1820s Sussex, amateur geologist Gideon Mantell finds something nobody can explain. It looks like a huge tooth - but what kind of creature did it belong to? And how does it fit into the story of an earth created by God just 6,000 years ago? Based on the true story of one man's battle to be heard, this is the 19th century as you've never seen it - filled with scientific endeavour, bitter rivalry and terrible lizards. It's 1961 and the concrete's just been poured for a brand-new housing estate.
