Spinosaurus Question

[Ravenstar <ravenstarstudios@charter.net>]

hey guys i have been looking at what I can find on the net about the 
Spinosaurus that was destroyed in ww2. most of it is art work and few pics 
of part of the back , neck and lower Jaw .
What i have always wondered is were there ever any leg or hip bones found to 
indecate that it was a Bipedal and not  quadrupedal?
just from what little I see  and I know th elay out of the bones were done 
in the early 20th century , it reminds me more of a Dimetrodon with a croc 
jaw.
just wondering.
