The names Eugongbusaurus and Proyandusaurus were created by Fabien Knoll in the 
abstracts of the 4th EWVP (Knoll, 1999), due to a mistake of the editors of the 
volume with an early version of Fabien´s abstract.

The status of the ?chinese fabrosaurids? (Agilisaurus, Gongbusaurus, 
Yandusaurus, Xiaosaurus) and any other dinosaur classed by any author as 
?fabrosaurids? (i.e. Fabrosaurus, Lesothosaurus, Pisanosaurus, Azendohsaurus, 
Galtonia, Technosaurus, Revueltosaurus, Lucianosaurus, Tatisaurus, Tawasaurus, 
Scutellosaurus, Alocodon, Nanosaurus, Trimucrodon, Echinodon, Taveirosaurus, 
?juvenil Scelidosaurus?, ?Lias Hypsilophodon?) has been revised in Knoll´s 
Thesis (Knoll, 2002), but the results had not been published yet.

Pete Buchholz:

The fact that the especies Y. multidens should be placed in its own genus has 
been published in papers of Buchholz (1997) and Knoll (1999, 2002).
