Canon royal de Turin
Dating the Third Dynasty is similarly challenging. Shaw gives the dates as being approximately from 2686 to 2613 BCE. The Turin King List suggests a total of 75 years for the third dynasty. Baines and Malek have placed the third dynasty as spanning the years 2650–2575 BCE, while Dodson and Hilton date the dynasty to 2584–2520 BCE. It is not uncommon for these estimates to differ by more than a century.
