Union Square in Somerville in Middlesex County, Massachusetts — The American Northeast (New England)
A Moment In Time
Near this spot on April 17th, 1832, Jonathan W. Niles unearthed the first complete Anchisaurus skeleton. Niles, an employee of the Milk Row Bleachery, found the discovery while working to fill the Miller's River marsh (which now is the stretch of Somerville Ave between here and the Washington Street intersection). He is known for widely publicizing and leveraging the discovery for personal gain. Niles and his wife Helen moved in 1854 and showed the skeleton in their home at 91 Summer Street, Boston.
In 1867, Alfred Worchester, a student of Harvard Medical School, inspected the bones authenticity and concluded the find to be a hoax. Worchester stated that Niles had merely arranged the bones of a German Shepherd and a common horse together in a convincing manner. Before this accusation could be confirmed the Anchisaurus skeleton was destroyed in the Boston Fire of 1872, which also took the life of Jonathan Niles and his wife Helen.
