Gideon Mantell, the palaeontologist who discovered the species, was born in Lewes.
Travelling through the Bronze Age (c.1400 – 1240BC), visitors will see one of Sussex’s most exciting archaeological discoveries of the last 50 years - a Middle Bronze Age Hoard complete with five Sussex Loops.
Through paintings and artefacts, exhibition, entitled The Sussex Archaeological Society: 175 Years of Collecting, will bring to life the stories of everyday people, sailors, prisoners and even one of America’s founding fathers.
Museums officer Emma O’Connor said the objects on display make memories of Sussex’s past tangible for our visitors.
“The exhibition is all about people, with both personal and collective stories to discover.”
