A single data-set was used for all the analyses in this work.
Taken with permission as XML from the web-site http://dinosauricon.com/
Edited to remove data formatting errors.
Updated with new genera to the end of 2001.
Updated with information discovered since data was published, e.g. better dating of some type specimens.
NOT edited to conform to my view of reality – e.g. Giraffatitan survives as a distinct genus.
