Dragon's are large and in part being controlled by the magical ebb and flow of Nirn - to my understanding, and spotted with my opinion and speculation. We are seeing dragons being awakened by Alduin who is most powerful at this point because he was in Nord afterlife (didn't feel like misspelling it, lol) eating away and chowing down on powerful and epic souls. Numinex was captured and probably began to wither away some while trapped there with Olaf. As the Dovah are strongly tied to the magical nature of things, it only makes sense that as hte magical powers within and around Numinex began to wane, so too did his overall size. By the time of his death one could imagine he was half as powerful as he was at his peak, thusly he was half the size...

...or he was the dumb dragon and only half as smart, therefore his skull only had to be half as large. Just saying, he was caught in a silly trap!
