And no. Spinosaurus Aegypticus was not completely bipedal nor completely quadrupedal. It was semi-quadrupedal.

But really, it's your choice on which theory you like best, and you can go with any theory on spinosaur's legs. I personally prefer the semi-quadrupedal theory.

I mean, who wouldn't love a bipedal amphibious theropod with a thick sail that also went on all fours from time to time, especially in water?

Anyways, it really depends on how you view spinosaurus. You can view it as quadrupedal or bipedal all you want. It's your choice!
