RE: Dwarf quadruped dinosaurs

["Sebastian Apesteguia" <ninjasarg@hotmail.com>]

OK, my first attempt was to write 'no larger than elephant size', but 
watching the collections of the Lillo Institute, La Plata and Cinco Saltos 
materials you would easily realize that most saltasaurines, and especially 
Neuquensaurus, had humerii lenght ranging from 45 to 60 cm, and femora close 
to 1 m in length. Do you want them to reach 10 m? So add them a long tail 
and neck, but their bodies and their mass are between a horse and an 
elephant, no more. Actually even with tail and neck they probably not 
exceded 6 m. Believe me, thay are really small.

ps: Oh, by the way, argentinian horses, extant and fossils (Hippidion) are 
specially low, but this has probably nothing to do with sauropod history.
