elephant birds versus thunder birds

[GSP1954@aol.com]

Perhaps some of you folks down under can help out, eh? Am doing a skeletal 
restoration of Dromornis (in part after Murray & Megirian 1998), and want to 
scale it to the largest example known. Supposedly dromornithids are the 
largest birds, but so far have not come across that exceeds the 810 mm 
tibia-astragalus length cited by Monnier for Aepyornis (do not have access to 
Rich 1979 here at Hopkins). Measurements of a larger dromornithid would be 
appreciated.
