Fascinating! Thank you!
The only other agent for specimen wear besides water transport that I can think of is digestion (though I think that usually results in detectable micro-pitting).

 

EDIT: The wear and polish exhibited on your specimens reminds me very much of the 'wave polishing' so familiar to me on small Calvert Cliffs sharks teeth (though that wear is post-depositional for the most part).

@ynot @Fossildude19 No worries, and thank you!

 

@Auspex Thanks for the suggestion, this was definitely pre-depositional wear as these pieces were all in-situ in the matrix blocks so it's interesting you mention the parallels to wave wear which backs up that they were exposed to a higher energy environment than just the calm pools. 

 

@doushantuo Thank you, and thanks for the PDF, I've been looking for a accessible copy of that paper for a while to try and see if I can determine the age of some of my micro mammals so it'll definitely come in handy.
