White rhino c.2001

A re-upload. These photos had been deleted in 'The Great Purge' but I've been thinking more about them recently. This animal had been at the zoo for many years, and one year we were told that DNA tests had come back, and instead of being worth $25,000, it was actually worth $250,000! My assumption was that it must have been a Northern White rhino, but I have never found evidence to back this up. I believe it's especially difficult to move towards a subspecies without even a horn. I have three questions: Does anyone know any definitive characteristics to differentiate the two subspecies of white rhino? (I'm unconvinced about hairiness of ears) Could this be a Northern white rhino? What's the bony growth on its shoulder bulk? I've seen mild keratotic changes in other rhinos but never anything like this. Perhaps a massively elongated spinous process?

      Somewhat reminiscent of Durer's rhino's horn.

      I'm not sure how much help it will be because a lot of the differences are via measurements and I gather much of the external stuff (e.g. hairiness) is open to opinion, but Darren Naish did a bit about them on Tetrapod Zoology in 2010 (with regards to Groves' splitting of them). I bolded the bits about external factors.
