Worn molar fragment - woolly rhino?

[Sebassie]

I’ve found this worn down molar fragment on the Zandmotor beach in the Netherlands. This beach is known for Pleistocene mammal finds.
 

My first guess would be a partial molar from a very old woolly rhino, but it may be another species. I’m quite sure the animal that it came from must’ve reached old age due to the fact that the chewing surface seems so chewed down, not broken that way. Please let me know what you think!
