• Published in a 1965 research article by Bullard et al, The Fit of the Continents Around the Atlantic in Royal Society of London Philosophical Transactions.

• Anteceded by numerous mappings of the apparent Atlantic fit of continents (notably Alfred Wegener's Origin of the Continents and Oceans) Bullard and his co-workers produced the first computer-generated map of the 1000 metre isobath fit, and in so doing contributed to the plate tectonic revolution.
