'Size' isn't necessarily overall length; a heavier animal with a shorter 
length may be considered 'bigger' in some fashion.

Did anyone ever try to estimate the total length of Spinosaurus in 1915, and 
if so, what was the estimate at the time? It's only with hindsight (and 
better preserved close relatives) that we know what the spinosaur body plan 
was like.
